JNANARJANA 2K14, 6 th National Scinece Conference on “Beyond the frontiers in Science & Technology” OP-LS-01 IMPACT OF CIGARETTE SMOKE ON HUMAN PERIPHERAL BLOOD LYMPHOCYTES – EFFECT OF ASCORBIC ACID SUPPLEMENTATION AND ITS IMMUNOLOGICAL SIGNIFICANCE Anupama Singh, Uthayasuriya, Anjali , Bhavya and Sreepriya M * *Department of Microbiology & Biotechnology Bangalore University, Bangalore – 560 056 ABSTRACT Cigarette smoking has been implicated as a predisposing factor in several human diseases including cardiovascular disease, malignancy and other inflammatory diseases of the airway and lungs. Smoking is also reported to suppress the immune responses leading to the increased susceptibility of smokers (both active and passive) to microbial infections. Antioxidant supplementation in vivo has been found to negate cigarette smoke(CS) – induced pathological and biochemical changes in animal models. The current study was designed to understand the effects of supplementation of the antioxidant ascorbic acid to prevent cigarette smoke-induced cytotoxicity and alterations in cell morphology. As lymphocytes are the principal mediators of immune response, human peripheral blood lymphocytes were used as the model systems in the study. Cell viability was evaluated by MTT assay and cell morphology by phase contrast microscopy analysis. Results indicated that exposure of human peripheral blood lymphocytes to cigarette smoke for about 7.5 seconds resulted in severe cellular damage and cytotoxicity. Pretreatment of the cells with ascorbic acid at a concentration of 10μg/ml considerably protected against CS-induced cytotoxicity. Also, it was observed that post treatment of the cells with 10μg/ml of ascorbic acid after CS exposure did not protect the lymphocytes against damage and a higher concentration of 30μg/ml and above was required to observe the protective effects. Results implicate the immunosuppressive effects of CS in vitro and the beneficial effects of ascorbic acid supplementation to combat CS-induced damage in human peripheral blood lymphocytes and thereby its role in boosting up the immunity of an individual. Key words: Cigarette smoke, lymphocytes, ascorbic acid, MTT assay, cytotoxicity

JNANARJANA 2K14, 6 th National Scinece Conference on “Beyond the frontiers in Science & Technology” OP-LS-02 PROTEIN PROFILE AND PHYSICO-CHEMICAL PROPERTIES FO HONEY Jyothi S. C., Akshatha Avadhani, Surendra N. S. Department of Biological Sciences, Bangalore University, Bangalore. ABSTRACT Honey is the yellow color liquid produced by honeybees from the nectar of blossoms, sucking insects living on parts of plants. When the nectar is passed from bee to bee before being stored in the cells of the hive, more secretions from the salivary and hypo-pharyngeal glands of foraging bees are added enabling the nectar to ripen into honey. Honey is a complex mixture and presents very great variation in composition and characteristics due to its production by different bee species during different seasons with different floral composition by differing harvesting and post harvesting techniques, all of which greatly influence the quality of honey. The genus Apis includes 7 recognized species of honey bees of which 4 are major groups & the other 3 are minor species. The major species include 2 hive bees’ namely A. mellifera & A. cerana. The widely available and commercially used honey is obtained from A. cerana. The present study reveals that there is a significant variation with respect to physicochemical properties such as pH, total dissolved solids (TDS), conductivity, density, viscosity, moisture content, optical density (OD), total carbohydrates, total reducing sugars, glucose % by mass, fructose % by mass, laevulose/ dextrose ratio, protein content, catalase activity, total phenolics, flavonoids, ascorbic acid, acid value and protein profile of unprocessed hive honey. This when compared with commercial/branded honey samples also showed the significant variations. These variations are due to biotic and abiotic factors. The degrees of variation between the raw and commercial honey is due to processing of honey. The quality of commercial honey can be maintained by improved processing technology and variations, which are seen among the raw honey. The T-test values with respect to the various raw honey samples were obtained from the beekeepers in different natural geographical regions of Karnataka. The sensory characteristics of the honey, of different regions of Karnataka are described together with physico-chemical and protein profiling analysis. However, this kind of studies are further required in various The Oxford College of Science, Bangalore
17
JNANARJANA 2K14, 6 th National Scinece Conference on “Beyond the frontiers in Science & Technology” other parts of the state, in specific and at large, the nation. This helps to understand the physico-chemical properties, protein profile and other parameters of honey needed for further understanding.
OP-LS-03 ANTI-INVASIVE, ANTI-ANGIOGENIC AND PRO-APOPTOTIC POTENTIAL OF EMBELIN AGAINST HUMAN COLON CARCINOMA CELL LINE- HT-29. Sumalatha.K.R and M.Sreepriya* *Department of Microbiology and Biotechnology Bangalore University, JnanaBharathi Campus Bangalore 560 056, Karnataka, India ABSTRACT Colon cancer is the third most common cancer in men and the second in women worldwide. Decades of expensive and replicating research studies have had little impact on primary prevention. Our previous findings demonstrated the growth inhibitory effects of embelin in human colon cancer cell line HT-29. In the present study, we aimed to further examine the potential of embelin in controlling angiogenesis and tumor cell invasiveness, proliferation and pro-apoptotic potential against invasive human colon adenocarcinoma cell line HT-29. A battery of relevant and powerful short term in vitro assays were conducted to check for the effects of embelin on cell proliferation (Sulphorhodamine B assay , BrdU incorporation test), Pro apoptotic effects (TUNEL assay, COMET assay, Annexin-FITC labeling and DNA fragmentation assay) anti-invasive effect (Boyden chamber assay and scratch assay) and angiogenesis ( in vitro angiogenesis assay). Influence of embelin on the expression of p53, Caspase 3 and 9, Bcl2, XIAP and TNF-α was investigated by reverse transcription PCR. A significant decrease in cell proliferation was observed on embelin treated HT-29 cells coupled with a drastic reduction in the number of capillary like structures formation on matrigel coated plates implicating the effect of embelin on cell migration and invasion. Increased number of comets, phosphatidyl serine externalization, increased expression of

JNANARJANA 2K14, 6 th National Scinece Conference on “Beyond the frontiers in Science & Technology” p53, Caspase 3 and 9 with increased expression of Bcl2, XIAP and TNF-α was observed after treatment with embelin thereby confirming its proapoptotic effects. Conclusion: Embelin inhibits angiogenesis, cell invasion and proliferation. It was also observed that embelin is selectively cytotoxic on carcinoma cells as opposed to normal cells. This is hypothesized to be partly mediated by upregulation of the p53 signalling pathway and its inhibitory effects on XIAP. Current study supports its therapeutic use in the treatment of advanced and metastatic colon cancer. OP-LS-04 FABRICATION AND ANTIPSEUDOMONAL EVALUATION OF PLANT EXTRACT LOADED CHITOSAN SPONGES FOR PROSPECTIVE BIOMEDICAL APPLICATIONS Adheena K.S 1, Ibrahim V 1, Asha ninan 1, Jayachandran V.P 2 1. PG Department of microbiology, The Oxford College of Science. 2. Pushpagiri Research Centre, Pushpagiri Institute of Medical Sciences, Tiruvalla ABSTRACT Chitosan (CH) is a natural mucopolysaccharide of marine origin consists of a linear (1-4) linked 2-amino-2-deoxy-D glucan, can be chemically prepared from naturally occurring chitin by treatment with alkali at elevated temperature. CH is non-toxic, biodegradable and biocompatible polymer possessing antibacterial, heavy metal adsorption, antioxidation and film forming properties. The cationic properties of CH offer the added advantage of electrostatic interactions with other anionic polysaccharides. It complex with negatively charged moieties such as sodium carboxymethylcellulose, citrates, pectin, acacia, agar, sodium caprylate, stearic acid, gluteraldehyde, sodium tri-polyphosphate, lactic acid, malic acid and alginic acid. In addition CH acts as a penetration enhancer by opening the tight epithelial junctions and this property of CH underlines the futuristic applications in protein and vaccine delivery. The prime objective of this study is the development and characterization of CH sponge loaded with plant extracts as well as the evaluation of the antibacterial potential. Various Sponges were prepared by dissolving CH in (2%) acetic acid with different The Oxford College of Science, Bangalore
19
JNANARJANA 2K14, 6 th National Scinece Conference on “Beyond the frontiers in Science & Technology” concentrations of CH (4% 6% 10%). On freeze drying, using more concentrated CH enhanced pore density of the sponge. The sponge prepared was cross-linked with sodium triphosphate solution and the morphology of CH sponges were characterized under a scanning electron microscope (SEM).
The sponges were loaded with selected plant
extracts to study its antibacterial activity. The water sorption capacity was checked by weighing the CH sponge (W1) and then immersed in phosphate buffer (pH 7.4; immersion medium), sponge remnants were wiped off excess surface water using filer paper and weighed (W2) at different time intervals. The immersed sponges were dried at 60°C for 24h and kept in a desiccator for 48h prior to reweigh (W3). The water sorption was calculated using the following formula: %water sorption = (W2-W3)/W3x100. Aqueous extract of Punica granatum, was prepared using decoction method and on filteration, centrifugation the extract was dried using vacuum evaporator to obtain a residue of crude extract. The sustainable antibacterial activity of drug loaded sponge was assessed using agar diffusion method. Sustainable antibacterial activity of developed sponge was evident against Pseudomonas aeruginosa and can be utilized as a therapeutic strategy against bone infections after clinical trials. Key Words: Multiple drug resistant Pseudomonas aeruginosa (MDR PA), Punica granatum, CH-chitosan, SEM, FT-IR analysis.

Although the primary interest is in diseases caused by these interactions, it must also be appreciated that microorganisms play a critical role in human survival. The microbial flora in and on the The Oxford College of Science, Bangalore
20
JNANARJANA 2K14, 6 th National Scinece Conference on “Beyond the frontiers in Science & Technology” human body is in a continual state of flux determined by a variety of factors, such as age, diet, hormonal state, health, and personal hygiene. An understanding of medical microbiology requires knowledge not only of the different classes of microbes but also of their propensity for causing disease. Nosocomial infection is defined as an infection which develops 48 hours after hospital admission or within 48 hours after being discharged. The objectives were to assess the frequency of nosocomial infection in patients admitted to intensive care unit (ICU) and to determine the etiological factors in such patients. Bacteria were isolated from most of the samples. Relevant samples from patients suspected to have infection were cultured and sensitivity testing was performed according to standard procedures. Members of the family Enterobacteriaceae are among the most important bacterial human pathogens accounting for the majority of bacteria isolated from clinical sample. The most frequent site of infection was respiratory tract (23%) and urinary tract (23%). Pseudomonas (P.), Klebsiella (K.), Escherichia (E.) coli, Acinetobacter and Candida spp. were the commonest organisms. The isolation rate of Gram-positive bacteria was relatively low. Majority (> 50%) of the Gram-negative isolates were resistant to many of the antibiotics tested. Relatively low resistance was only observed against Tobramycin. Majority of Gram-negative isolates were resistant to Ceftizoxime and Ciprofloxacin. The high frequency of HAIs and antibiotic resistance rate, suggests that more strict infection control practices along with prescription of antibiotics after antibiotic susceptibility testing should be implemented to limit the emergence of antibiotic resistant organisms. Patients admitted in intensive care unit are at more risk of acquiring nosocomial infection from different sources. It is suggested that proper nursing care, sterilization and disinfection of instruments and equipment and careful handling of invasive procedures are the best tool to control these life threatening infections.

The current study aimed to isolate amylolytic and cellulolytic bacteria associated with the gut of Oryctes rhinoceros. These insects are major pests of coconut, oil and other palms but they contribute to important ecological functions such as nutrient cycling. Freshly cultured larvae of Oryctes rhinoceros were used to isolate and identify the micro organisms associated with them. The microbes were cultured from the gut of the samples on nutrient agar. Total of 9 bacterial colonies were isolated. DNA was extracted and nearly full-length bacterial 16S rDNA fragments were amplified by polymerase chain reaction (PCR) from each representative bacterial isolates. The PCR products were sequenced, and the sequences were aligned against those sequences found in the NCBI database using the BLAST (Basic Local Alignment and Search Tool) algorithm. The analysis revealed that the gut of larvae Oryctes rhinoceros contain a complex gut microbiota including Lysinibacillus sphaericus, Bacillus subtilis, Bacillus amyloliquifaciens, Bacillus megeterium, Bacillus methylotrophicus, Bacillus altitudinus, Bacillus tequilensis, Staphlococcus saprophyticus.

[email protected] ABSTRACT Polyhydroxyalkanoates (PHAs) are polyesters of hydroxyalkanoates synthesized by various bacteria as intracellular carbon and energy storage compounds and accumulated as granules in the cytoplasm of cells. PHA producing bacteria from activated sludge and soil were isolated, characterized and screened by Sudan Black staining method. All the potential PHA producers were isolated, out of which two of Bacillussp and one of Pseudomonas sp and it was confirmed by their morphological and biochemical characters. PHA was extracted directly with solvent chloroform and estimated spectrophotometrically. Optimization of PHA accumulation was carried out at deifferent temperature. The strain PHA-1 showed higher amount of PHA accumulation when compared to the other strainsi.e. 52 mg/ml. The world wide dependence on petroleum by products for the manufacturing of plastics, scarcity of space for disposal and growing environmental concerns over non biodegradable synthetic plastics have fuelled research towards development of eco friendly biopolymer material. Hence, attention has been laid on production of Polyhydroxybutyrate, one of the most extensively studied PHA, is an intracellular microbial thermo plastic that is widely produced by bacteria present in soil.

In recent years, natural compounds such as phenolic acids, flavonoids, triterpenes and alkaloids present in various plants, act as potential anti diabetic and anti-inflammatory agents. The main difficulties in using natural products as a source for pharmaceutical lead compounds involve separating the compounds from the crude extracts. In search for novel anti-inflammatory and antidiabetic plants are still intensifying. This study, confirms different plant species revealing anti-inflammatory and anti-diabetic capabilities along with their other medicinal activities. Peripheral inflammation involves an increase in cyclooxygenase-2 (COX-2)-mediated prostaglandin (PG) synthesis in the central nervous system (CNS), which contributes to allodynia and hyperalgesia. In the present study we have determined the changes in prostanoid tissue levels and in expression of terminal prostanoid synthases in both the CNS and inflamed peripheral tissue during carrageenan-induced paw inflammation in the rat. Prostanoid levels were measured by liquid chromatography-mass spectrometry and enzyme expression at the RNA level by quantitative PCR analysis during both the early (1-6 h) and late (12 and 24 h) phases of the inflammatory response. In the paw, the early phase was associated with increases in PGE2 and thromboxane (TX)B2 levels and with a peak of COX-2 expression that preceded that of microsomal prostaglandin-E2 synthase-1 (mPGES1). COX-2 and mPGES-1 remained elevated during the late phase, and PGE 2 continued to further increase through 24 h.. The results show that the carrageenan-induced edema in the paw elicits an early phase of COX-2 induction in the CNS leading to an increase The Oxford College of Science, Bangalore

OP-LS-09 PRODUCTION AND OPTIMIZATION OF CELLULASE ENZYME BY Aspergillus niger USING PINEAPPLE PEEL AS SUBSTRATE Abdul Nayeem, Atul Chandra, Ganesha R, Dhondup Namgyal, and Kiran Kumar S P.G. Department of Biotechnology, The Oxford College of Science, HSR Layout, Bangalore. ABSTRACT The bioconversion of agro-waste based lignocellulosic material to energy has gained much interest during the recent past. The enzymatic degradation of waste cellulose by fungal enzymes has been suggested as a feasible alternative for the conversion of lignocellulosic material into fermentable sugars and ethanol. Cellulose is the principal constituent of the cell wall of most terrestrial plants. Despite a worldwide and enormous utilization of natural cellulosic sources, there are still abundant quantities of cellulose-containing raw materials and waste products that are not exploited or which could be used more efficiently. Pineapple is a tropical plant and fruit. Its scientific name is Ananas comosus and it belongs to the family Bromeliaceae. The agro-waste can be effectively utilized for the production and characterization of cellulases by Aspergillus niger on pineapple agro-waste . Cellulase production from cellulosic pineapple waste using Aspergillus niger was assessed. The pineapple peel waste were dried, pre-treated with alkali and re-dried and then blended. The powdered waste was then used as substrate in separate shake flask which contain mineral salt medium MSM and inoculi of Aspergillus Niger. Fermentation were carried out in flask containing the MSM (Mineral Salt Medium), the waste substrate and the inoculumn at pH 5.0, 1% substrate concentration, 10% inoculum size (1 ml) and cultured on a rotary shaker (250 rpm) at 29±1˚C initially for 5 days to verify cellulase production by the organism from the waste substrate, the for 7 days, while varying different fermentation The Oxford College of Science, Bangalore

Cellulase activity and amount of glucose produced by the test organism’s i.e from the waste substrate were determined and compared. The amount of glucose produced was optimized by varying the fermentation parameters: Time, pH, Substrate concentration, Inoculum size and Temperature. The studies showed that 5gm substrate at 8th day of fermentation has higher specific activity of the enzyme and for pH, the optimum is pH 6 on 6 th day, inoculums size is 5ml and temperature is 45˚C. Though the present study is a small scale process, yet by using the optimum parameters, it revealed that the following study can help to enhance the production of cellulase. The study revealed that pineapple peel which is an examples of domestic and industrial agro-waste , produce large amounts of cellulase enzyme when hydrolysed by cellulolytic microorganisms and instead of being left behind for natural degradation can be utilized efficiently under the above mentioned conditions to produce enhanced amount of cellulase which has massive role in various industries.

ABSTRACT Environmental contamination of soil by trace metals is a serious problem worldwide due to their accumulation in food chain. Many plant species are sensitive to micro molar concentration of aluminum (Al) when present in acidic soil and it is one of the potential toxic metal for human health. Al induces the oxidative damage in the plants during accumulation. Plants exhibit some defence mechanism to overcome the stress due to metal exposure through their antioxidants. In this study, the effect of Al stress on growth and other related antioxidants and scavenging enzymes were investigated in Amaranthus tricolor L. Al induced growth retardation observed more in roots compared to shoots. The antioxidants and enzymes exhibited initial increase and subsequent decrease in response to Al stress.

[email protected] Plastics are synthetic substances produced by chemical reactions. The issue of plastic waste management is a complex process and there is no simple solution for reducing this waste. Plastic causes serious damage to the environment, both during its production and disposal. Biodegradation of plastic waste using microbial strain could offer a solution to this problem. Microorganisms have been a good resource for solution to this problem due to their diverse metabolic capability, adaptability to different environment and possibility of isolation using artificial growth media for utilization in situ. In the present study, potent microbial strains degrading plastics constituting poly vinyl chloride (PVC) and low density poly ethylene (LDPE) were isolated using soil burial technique. To increase the chances of isolating such strains which could have adapted to metabolize plastic constituting polymers, samples were collected from Mavalipura dumpsite, Bangalore that was rich in plastic waste. At the end of the study, Kingellasp.,Actinomycessp,,Alkaligens sp.,Methylobacillussp.was identified. The microbial species associated with PVC were Kingella sp., Actinomyces sp. and LDPE were Alcaligens sp., Methylo bacillus sp.The biodegradation of the respective plastics was analyzed for after 2 months, 3 months and 4 months of incubation in invitro condition.

Department of Studies and Research in Microbiology, Sahyadri Science College (Autonomous), Kuvempu University, Shivamogga-577203 ABSTRACT Actinomycetes are gram positive bacteria characterized by characterized by the formation of substrate and aerial mycelium on solid media, presence of spores and a high GC content of the DNA (60-70 mol %). In nature, biodegradation by actinomycetes plays an extremely useful role in waste removal and is an integral part of recycling of materials in nature. Actinomycetes decompose many substrates found in soil and act as scavenger which explains its potential to use diverse substrates by producing specific enzymes. 20 different Actinomycetes were isolated from the soil of Western Ghats. They were tested to produce enzymes such as cellulase, amylase, gelatinase, L-Asparginase, Pectinase, lecithinase, lipase, lysine decarboxylase, oxidase, catalase, caseinase. The specific substrates were given as the sole carbon source in respective medium. The utilization of substrates by the Actinomycetes isolates was tested using a simple sensitive agar plate with specific media. The positive result was shown by the presence of zones and the specific color produced by the colonies of isolates. It was found that Actinomycetes utilized almost all of the substrates. Maximum results were found in the utilization of cellulose, starch, casein, lipids, and gelatin. More than half of the isolates were able to utilize lysine, egg yolk and showed positive result. Very few isolates produced specific enzymes to utilize L-aspargine and pectin. The Oxford College of Science, Bangalore

The objective of our study is to analyse the prophage region, its annotated features, their role in virulence and host specificity in all these genomes. Over extensive studies these Prophages were found in mediating serovar based divergence in Salmonella species. After computational analysis of the Prophages, our study revealed that prophage regions are present along with Salmonella genome which were found to encode structural proteins as well as other proteins which contributes to Salmonella pathogenicity. Through computational analysis 52 nonredundant prophages like regions, among them some prophage elements like Gifsy_2, Entero_2 etc were found at multiple locus within Salmonella genome. Out of fifty two, 20 were serovar specific and 22 were found to be strain specific Prophages. 5 Prophages like entero_ES18, Salmon_1, Yersin_413C, Salmon_SPN3UB and Stx2_c_1717 were found to encode host specific proteins.

India has more diabetics than any other country in the world, according to the International Diabetes Foundation. The disease affects more than 62 million Indians, which is more than 7.1% of India's Adult Population. An estimate shows that nearly 1 million Indians die due to Diabetes every year. The average age on onset is 42.5 years. The high incidence is attributed to a combination of genetic susceptibility plus adoption of a high-calorie, low-activity lifestyle by India's growing middle class. The Part 1 study conducted in the year 2013 revealed that incidence of diseases like diabetes mellitus, cardiovascular disorders and arthritis is more prominent in urban population than in rural masses. A Part 2 study was conducted in the year 2014 to highlight on the link between the genetic and the lifestyle component in these diseases. Aspects such as stress levels, alcoholism and fitness were taken into consideration. The only chosen subjects were cases with familial diabetic history and the additional health complications they suffer were noted. It was seen that the genetic predisposition with modern lifestyle reduces the age of onset of the diseases in subsequent generations – a phenomenon termed as Genetic Anticipation.

P2 1Centre for Applied Genetics 2Department of Zoology, Bangalore University, Bangalore-560 056, Karnataka, India ABSTRACT Morphological study of termites is the most neglected criteria for assessing variation. In this study 33 samples were collected from different localities of Bangalore which revealed five widely distributed species Odontotermes ceylonicus (Wasmann), O. horni (Wasmann), O. obesus (Rambur), O. redemanni (Wasmann) and Trinervitermes biformis (Wasmann). The morphological data was subjected to different modes of statistical analysis. Manhattan distance was constructed by coding mean values of different traits among the studied populations. The Manhatten distance was compared with the dendrogram obtained by coding Tukey-Kramer test (post hoc test) results from McQuitty distance. According to Manhattan distance the similarity between the populations of the species was as expected. In this analysis O. redemanni and O. obesus shows 100% similarity because the traits by which the species are distinguished are not considered. The reason behind this is that not all the species in this study contains mandible and left madibular tooth. The Tukey-Kramer analysis O. redemanni and O. obesus show 50.31% of similarity which is an actual indication of correlation coefficient. The correlation coefficient values were significant enough even though the traits distinguishing the species were not considered. Due this reason for the present study involving post-hoc test followed by correlation coefficient distance method served more accurate results than Manhattan distance using the coded mean values.

Maximum biomass production was achieved using 7.5% cow urine as the growth enhanced more than double in comparison to normal Fogg's medium. The pH of both the medium was found to be between 7-8 which is found to be favorable for Chlorella growth. Various parameters such as lipid, protein and carbohydrate content was determined quantitatively and compared with normal grown cells. The lipid content was found to be 34.7 % when 10 % of cow urine was used and 22.7% for 7.5% of cow urine used, which is found to be much higher than the Chlorella sp. grown under normal Fogg’s media (7%). The protein content was also enhanced when cow urine was used to grow the algal cells (50.17%) in comparison to normal grown cells (38.24%). Carbohydrate content was reduced approximately to half in cow urine medium. The fatty acids produced were also shown to differ in its composition when characterized by GC-MS. The study confirms the use of Cow’s waste (cow urine) that is a rich source of carbon, nitrogen, phosphorus and other micronutrients as a favorable medium for cultivation of microalgae and bio-diesel production. Keywords: C. vulgaris, C. sorokiniana, C. heliozoae, C. lobophora and Chlorella pyrenoidosa, bio-diesel, cow waste, lipid content,

[email protected] ABSTRACT Pseudomonas aeruginosa is a gram negative bacterium whose preferred mechanism of metabolism is respiration. Thus it uses animals as host and its versatility enables it to infect damaged tissues or even human with reduced immunity. P. aeruginosa are much more complicated and can be life-threatening. Hence there is an immediate need for an efficient drug or agent that can act as a magic bullet for the treatment of MDR P. aeruginosa infections. Quercetin is a flavonoid it is found in fruits, vegetables, leaves and grains. So far there are no reports available on antiquorum sensing activity of Quercetin. Hence in the present investigation, we made an efficient attempt in evaluating the antiquorum sensing property of quercetin against MDR P. aeruginosa in a dose dependent manner. Antiquorum sensing activity of quercetin was studied by minimum inhibition concentration (MIC) assay, swarming motility assay, flask incubation assay, and agar well diffusion assay. MIC assay revealed that at160 µg/mL showed singnificant activitiy against MDR P. aeruginosa. Agar well diffusion method also supported the results of MIC assay by showing 16 mm zone of inhibition at same concentration. Swarming motility assay and flask incubation assay where in corroboration with MIC assay and agar well diffusion assay indicating that quercetin posseses potential antiquorum sensing activity against MDR P. aeruginosa. This investigation reveals that quercetin is a strong antiquorum sensing agent against P. aeruginaosa. Future investigation needs to be carried out to evaluate this property using in vivo models. Key Words: Pseudomonas aeruginosa, Quercetin, Multiple drugs Resistance (MDR), Minimum inhibition concentration (MIC) and Antiquorum sensing.

Raji Sukumar,Gayatri R.Iyer,Athulya Mohan,NijithaK., Naveen V. and Bushnin Patel. Department of Genetics,The Oxford college of Science,H.S.R. Layout, Bangalore ABSTRACT Oil spills have been recognized as one of the most serious current problem particularly in industrialized and developing countries. Inevitable spillages, which occur during routine operations of oil products, refining or as a consequence of acute accidents, lead hydrocarbons to reach the water table before becoming immobilized in the soil. This study, thus was aimed to assess the oil degrading potential of selected bacterial strain under in vitro conditions.The present study is carried out by isolation of oil degrading microbes from oil contaminated soil from the garages
of Bangalore and identification of the
enzymes needed for degradation and the isolation of the degradative plasmids from the micro organisms. Preliminary study was undertaken to determine the optimal conditions for the biodegradation of a crude oil. Among 28 oil-degrading bacterial cultures isolated from oil-contaminated soil samples, Bacillus sp, Pseudomonas sp were selected for the study based on the efficiency of crude oil utilization. Along with the selected individual strains, a mixed bacterial consortium prepared using the above strains were also used for degradation studies. The culture medium included essential nutrients with prime carbon source as the diesel oil.The mixed bacterial consortium showed more growth and degradation than did individual strains. Degradation activity was determined using DCPIP colorimetric analysis. 2,6-dichlorophenolindophenol is a chemical compound used as a redox dye. Oxidized DCPIP is blue in colour showing maximum absorption at 600nm. At 1% crude oil concentration, the mixed bacterial consortium degraded a maximum of 77% of the crude oil. Temperature of 35C and pH 7 were found to be optimum for maximum activity. Keywords: Bacteria ; oil Degradation; Hydrocarbons; DCPIP

Ramachandra Mohan Department of Zoology, Dayananda Sagar College of Biological Sciences, Kumaraswamy layout Bangalore: 560 078 Department of Zoology, Bangalore University, Bangalore: 560 056
ABSTRACT Histopathology of the Hypophysis and Ovary was observed during preparatory phase, the fish G. giuris on treatment with sublethal concentrations of Malathion ( 0.05 , 0.25 and 0.5 ppm) for 24, 48, 72 and 96 hrs intervals, histology represents a useful tool to assess the degree of pollution, particularly for sub-lethal and chronic effects. However, a standardized method for the description and assessment of histological changes, mainly for use in freshwater fish, is still lacking. In this paper, the present authors propose a standardized tool for the assessment of histological findings which can be applied to different organs. The results of the present study showed morphological changes in the cell structure. Investigation on Hypophysis and Ovary cells showed degranulation and hypertrophy of cells and nuclei after the fishes were exposed for 24 hrs Malathion treatment, these changes further intensified with 0.25 ppm treatment through the appearance of extensive intercellular spaces. In higher concentration of
Malathion
treatment with 0.5 ppm for 24 hrs, the cells showed various stages of degranulation which were distributed sparsely. A reduction in the number and diameter of the Hypophysis and Ovary cells indicates possible reduction in release of hormones. A higher concentration brings about rapid changes of Hypophysis and Ovary which indicating a possible reduction in the synthesis and release of hormones.

[email protected] ABSTRACT The actinomycete strain Streptomyces griseus isolated from soil is used for the production of streptomycin, a potent antibiotic drug which is of great commercial importance. The strain was identified by morphological features and several biochemical tests. Further they were grown as a pure culture in starch casein agar media. Mutation was done both by physical and chemical methods and it was found that the antimicrobial activity was increased by 10% for the mutated strain kept under UV light for 5minutes. Production was achieved by solid state fermentation using mousambi, pineapple and sugarcane waste as the substrate which are cheaply available. Purification was done by filtration with charcoal and acidified methanol followed by evaporation to produce antibiotic in powder form. High purity was obtained during analysis by High Pressure Liquid Chromatography (HPLC) and it is shown that the production increased by 24% with mousambi and 30% increase with pineapple while there is a 46.77% increase in production with sugarcane using the mutated sample. Hence it was concluded that mutation with UV light for 5mins and solid state fermentation using sugarcane as substrate yielded the best results. This paper also reviews the possible methods of increasing the production efficiency and cost effectiveness of streptomycin at the industrial scale.

[email protected] ABSTRACT Amylases (α-amylase, β-amylase and glucoamylase) are among the most important enzymes in present day biotechnology. Although amylases can be derived from several sources, microbial enzymes generally meet industrial demands. These enzymes, especially α-amylase have found wide applications in a number of industrial processes such as in the food, fermentation, textile and paper industries. Industrially important enzymes including amylases have traditionally been obtained from submerged fermentation (SmF) because of ease of handling and greater control of environmental factors such as temperature and pH.

47
JNANARJANA 2K14, 6 th National Scinece Conference on “Beyond the frontiers in Science & Technology” Solid state fermentation (SSF) constitutes an interesting alternative since the metabolites so produced are concentrated and purification procedures are less costly. Solid-state fermentation presents a series of advantages over submerged fermentations and these have been widely discussed in the literature. The culture conditions are more similar to natural habitat of filamentous fungi, so that they are able to grow and excrete large quantities of biomaterials. Products concentration after extraction is usually higher than those obtained by submerged fermentation and the quantity of liquid waste generated during the fermentation process is lower. SSF has gained renewed interest from researchers for enzymes production in view of its economic and engineering advantages and is often employed to produce amylases. Filamentous fungi have a number of properties which make them important both scientifically and industrially. They are also suitable microorganisms for SSF, especially because their morphology allows them to colonize and penetrate the solid substrate has been successfully used to express high levels of heterologous proteins and industrial enzymes. The present study was made to assess the effect of wheat bran and other environmental parameters such as pH, temperature, culture age etc. on the production of amylases, in particular, α-amylase. Aspergillus oryzae was collected from Dept. of Microbiology, The Oxford College of Science, Bangalore and pure culture was maintained on MRBA medium. Wheat bran was autoclaved and different ratios of minimal sat medium (1:1 and 1:5) were mixed and 1 ml of
A. oryzae spore suspension was inoculated into the flask
containing wheat bran and minimal salt medium. The production of α-amylase was determined at different time intervals of 48h, 72h, 96h and 120h and different inoculums size of 1 ml, 2 ml and 3 ml. The highest production of α-amylase was recorded at 120h with 1.0 ml inoculum. The effect of pH and temperature are being carried out.

Department of Biotechnology, The Oxford College of Science, HSR Layout, Bangalore. *Corresponding author:
[email protected] The discharge of heavy metals into aquatic ecosystems has become a matter of concern in India over the last few decades. These pollutants are introduced into the aquatic systems significantly as a result of various industrial operations. The pollutants of concern include lead, chromium, mercury, uranium, selenium, zinc, arsenic, cadmium, gold, silver, copper and nickel. These toxic materials may be derived from mining operations, refining ores, sludge disposal, fly ash from incinerators, the processing of radioactive materials, metal plating, or the manufacture of electrical equipment, paints, alloys, batteries, pesticides or preservatives. Heavy metals such as zinc, lead and chromium have a number of applications in basic engineering works, paper and pulp industries, leather tanning, organochemicals, petrochemicals fertilizers, etc. Major lead pollution is through automobiles and battery manufacturers. For zinc and chromium the major application is in fertilizer and leather tanning respectively. Over the few decades, several methods have been devised for the treatment and removal of heavy metals. Bioremediation consists of a group of applications, which involve the detoxification of hazardous substances instead of transferring them from one medium to another, by means of microbes and plants. This process is characterized as less disruptive and can be often carried out on site, eliminating the need to transport the toxic materials to treatment sites. The biosorption (sorption of metallic ions from solutions by live or dried biomass) offers an alternative to the remediation of industrial effluents as well as the recovery of metals contained in other media. Biosorbents are prepared from naturally abundant and/or waste biomass. Due to the high uptake capacity and very costeffective source of the raw material, biosorption is a progression towards a perspective method. The mechanism by which microorganisms take up metals is relatively unclear, but it has been demonstrated that both living and non-living biomass may be utilized in The Oxford College of Science, Bangalore

In the present study, soil samples were collected from Bellandur Lake, serially diluted and inoculated on Tryptone glucose extract agar plates with various concentrations of zinc ranging from 100 to 1000 mg/l. The minimum inhibition concentrations (MICs) revealed that four isolates were able to tolerate a high concentration of zinc (1000mg/l). The isolates were maintained by weekly subculturing on Tryptone glucose extract agar medium. All the isolates were inoculated to Tryptone glucose extract liquid medium and incubated on a rotary shaker at 280 C for 72 hours. The flasks were taken out after 72 hours of inoculation and were centrifuged at 10,000 rpm for 10 min at 4°C. After centrifugation the supernatant (three times washed with NaOH 1N) were digested with HNO 3 67% and H2O2 (30% v/v), and metal concentration was determined by atomic absorption spectrometry. The results showed that all the fungal isolates showed efficient Biosorption property. The isolate 8, showed maximum Biosorption compared to other isolates in the order 148>134>85>36 mg/l for the isolates Zn8>Zn4>Zn6>Zn1 respectively.

is
an
alternative
biofuel
which
is
produced
by
a
mono-alcoholic
transesterification process, in which triglycerides reacts with a mono-alcohol with the catalysis of alkali, acids, or enzymes. As known, biofuel can be produced from various plants. But their increased use for the production of biofuel may create an ecological imbalance and also affects the food security. This limits the use of plants and increases the use of microorganisms such as Microalgae in the biofuel production. Micro-algae are the fastest growing photosynthesizing unicellular organisms and can complete an entire growing cycle every few days. Some algae species have high Oil content and can produce up to 15,000 gallons of oil per acre per year under optimum conditions. Photosynthesis is the first step in the conversion of light to chemical energy and ultimately responsible for supporting all biofuel synthetic processes, converting solar energy into biomass, carbon storage products and hydrogen. Bio-Lipid oil can also be used to produce one of the lowest cost and most environmentally friendly fuels. Bio-diesel made from bio-lipid oil, from micro-algae, burns cleaner, produces less CO 2 than petroleum based diesel fuels, and it's renewable and sustainable. The algae used to produce the bio-lipid oil actually absorb CO2 from the atmosphere, thereby reducing dangerous, greenhouse gases that cause global warming. The aim of our project was to extract biodiesel from microalgae collected from the mass cultivation unit of Bangalore (GKVK) and from edible & non edible oils collected from oil The Oxford College of Science, Bangalore

PP-LS-15 SOLID WASTE TREATMENT AND ITS CONVERSION TO AN ECO-FRIENDLY PRODUCT BY EFFECTIVE MICROORGANISM (EM) TECHNOLOGY Madhumita Ghosh Dastidar, Shankar BS Department of Microbiology, Vijaya College, R.V.Road, Bangalore Email-
[email protected] ABSTRACT In a modern city life we have to deal with enormous wastes that generate everyday through industrial wastes and domestic wastes. The quantity of wastes generated due to urbanization pose a major problem of proper and adequate treatment and has an adverse effect on environment. Many scientific techniques have been discovered for proper waste management followed by its disposal. But today it is necessary to use such a method which can convert wastes to reusable products, thus aim to combat environmental pollution. The kitchen waste is one of the typical household generated waste shows a major impact on municipalities for the treatment. The waste management by Effective Microorganism (EM) technology has been adapted by many countries. The aim of this study is to find an easier solution to treat solid wastes by EM technology and conversion of the wastes to eco friendly products. This study has a number of applications including agriculture, livestock, gardening, landscaping, composting, bioremediation etc. The wastes have been successfully converted by EM methods. Also when analyzed the content of carbon, nitrogen and phosphorous of the wastes after EM treatment, it has been observed that these elements are increased which can be utilized as source biofertilizers.

[email protected] ABSTRACT Salon and spa are mushrooming everywhere and doing brisk business too. Salon waste products if disposed untreated causes adverse effects on health and surrounding environment which enhances the growth of various pathogens especially related to skin. The major health issues like skin rashes, eye irritations, scalp itching are caused by salon wastes like hair clippings, various chemicals, dyes and also used cotton, tissue paper etc. The aim of the experiments to analyze the indoor micro flora and also to find applications of salon wastes. We collected various samples like hair, nail scalp and skin swabs of salon worker and conducted various microbiological tests to analyze the internal environment of a salon. The industrial growth has accelerated the generation of various oily wastes especially from petrochemical, metallurgical industries and transportation and domestic sewage wastes. These wastes are major pollutant for aquatic environment. Industrial waste contain 75% free oil, 20% emulsified oil and 5% soluble oil. Separation of oil from surface of a large body of water is necessary otherwise aquatic life will be under threat. Everyday thousands of tons of hair are generated as wastes from salon which are thrown to landfills with no direct benefit. Moreover hair is a slow degradable product. Our aim is to find an effective means of utilizing the salon generated wastes hair to clear the oil spills. Human hair can adsorb various potential hazardous oils like crude oil, motor oil which upon spillage causes environmental pollution. We have tested the human hair oil adsorption capability by testing with various types of hair. The proportion of oil adsorption is quantified by considering various properties of oil adsorption. Finally we have converted the oil laden hair to an eco friendly bio-compost.

Department of Biotechnology, The Oxford College of Science, HSR Layout, Bangalore. ABSTRACT The toxicity to humans and other animals from antibiotics is generally considered to be low. However, prolonged use of certain antibiotics can decrease the number of gut flora, which can have a negative impact on health. The inevitable consequence of widespread and injudicious use of antibiotics has been the emergence of antibiotic-resistant pathogens, resulting in a serious threat to global public health. The resistance problem demands that a renewed effort be made to seek antibacterial agents effective against pathogenic bacteria resistant to current antibiotics. Possible strategies towards this objective include the increased sampling from diverse environments and identification of bioactive compounds produced by plants and other sources. Caesalpinia bonducella, commonly known as Gray Nicker, is a species of flowering plant of family Caesalpiniaceae, that has a pantropical distribution. C. bonducella Fruit is also known as a Fever Nut, due to its antipyretic properties. The seeds contain an alkaloid caesalpinine, bitter principles such as bonducin, saponins and mixed oils. These compounds render the herb its therapeutic properties. The plant treats skin diseases, ulcers and leprosy, gastrointestinal problems like, dysentery and diarrhea. C. bonducella seeds were collected from Junagadh forest, Gir area (Gujarat). C. bonducella seeds were crushed in a mixer & dry powder formed. The powder was subjected to soxhalet extraction. All the extracts at various concentrations were tested for antibacterial studies on various strain of microorganisms like Pseudomonas aeruginosa, Shigella dysentery, Proteus mirabilis, Staphylococcus aureus, Enterococcus faecalis. chloroform extract have showed good antibacterial activity against Shigella dysentery, Proteus mirabilis, pseudomonas aeruginosa, Enterococcus faecalis.

PP-LS-18 ELISA- BEST ADVANCED HANDY DETECTION TEST OF PICKING THE SPECIFIC PROGESTERONE METABOLITE IN FECAL SAMPLES OF WILD ASIAN ELEPHANTS! S.B.Chethna MSc. Biological Sciences, Bangalore University, Bangalore 560008 ABSTRACT Asian elephants (Elephas maximus) are prominent “flagship species”, are listed under the category of endangered species (EN-A2c, ver.3.2; IUCN Red list 2009) and there is need for their conservation. This requires understanding demographic and reproductive dynamics of species. Traditionally invasive blood sampling is carried out but this is restrictive for large animals and hence non- invasive methods are ideal to assess the reproductive cyclicity of elephants to detect the concentration of catabolised progesterone levels in female elephants. The diet and the ecological parameters are vital for normal progesterone synthesis. These are poly breeders and come into estrous about thrice a year due to longest estrous cycle of about 16 weeks. And only during estrus are the chances of pregnancy, which is directly proportional to progesterone levels. So assaying this technique by Enzyme linked immune sorbent assay (ELISA) is the latest and handy method. This advanced technique has ample advantages over Radio Imuno assay (RIA) and is highly specific and sensitive shows 90% binding to pick up this progesterone metabolite. The purpose of this study is to estimate the concentration of one of the progesterone metabolites i.e allopregnanolone (5α-P-3OH) in different fresh fecal samples of the random population subjected to a representative block of Asia. The results will help us out to predict the reproductive status for the localized population of female elephants, thereby helping to plan their breeding strategy. Keywords: Flagship, Non-invasive and reproductive cyclicity.

Stabilizers are complex polysaccharide which are added to food stuff like yogurt to enhance its texture, flavour. Lactic acid bacteria(LAB) are gram +ve, rod shaped bacteria which are mainly present in milk and its product like curd, yogurt etc. some of the species of LAB are considered to be Probiotic cultures. Soluble starch and stabilizer mainly contribute to firmness, viscosity, water holding capacity and protein stability in Yogurt. Soluble starch and Stabilizer were added to Yogurt with an aim to get Yogurt product with firmness, viscosity, flavour having considerable health benefits in condition like Antibiotic-associated diarrhoea(AAD), Pseudomembranous colitis etc. The objective of the work
was to observe the growth of lactic acid bacteria after
interaction of Soluble starch and Stabilizer. Different commercially available from of soluble starch were used out of which Curia-2 was screened and 1% concentration of Curia-2 was found to be the best and Sodium alginate was found to be the best out of different stabilizers used such as Pectin, Locust Bean Gum(LBG.)Raw milk sample used for Yogurt preparation contained 4% fat, 9.065% SNF, and 13.065% TS. Culture used for Yogurt preparation was Lactobacillus bulgaricus and Streptococcus thermophilus.The physicochemical characteristics of yogurt with interaction of soluble starch and stabilizer differ significantly In comparison with control sample. Addition of soluble starch and stabilizer enhances the consistency, firmness and adhesion of product.

In the present study, petroleum ether, chloroform, ethanol and aqueous extracts of Alstoniascholaris bark were screened for their bactericidal, fungicidal and anthelmintic properties. Antibacterial activity revealed that chloroform extract at the 20 mg/ml showed significant antibacterial effect. Nevertheless, petroleum ether, ethanol and aqueous extracts also showed antibacterial effect against E. coli and S. dyscentreae, but less effective than chloroform extract. All the extracts were not as potent as the standard drug ciprofloxacin. Fungicidal activity revealed that among all the test extracts, ethanol extract at 20 mg/ml showed significant fungicidal effect against Rhizopus. . Interestingly, petroleum ether and ethanol extracts at 20 mg/ml showed more significant fungicidal action when compared to standard drug sulphamethoxazole. Anthelmintic activity of A. scholaris extracts was carried out at four different concentrations viz., 2.5, 5.0, 10.0and 20.0 mg/ml to evaluate their effect in inducing paralysis and death in Pheretimaposthuma.

Sowmya Kumar * and M Sreepriya ** Department of Microbiology and Biotechnology, BangaloreUniversity, JB Campus Bangalore – 560 056 ABSTRACT Osteoporosis is a silently progressing metabolic bone disease, targeting mainly the women population. It is the major cause of morbidity, mortality and significantly affects the quality and life expectancy of elderly women. Ovarian hormone deficiency is the major risk factor for decreased bone mass and increased bone fragility in osteoporosis. HRT (Hormone replacement therapy) is considered as the mainstay treatment for osteoporosis but this is reported to increase the risk of breast cancer incidence. Other antiosteporotic drugs available in the market also causes an array of painful side effects. This has stimulated the interest in the clinical development of SERMs as antiosteoporotic agents. The aim of the present investigation is to study the effect of Formononetin and Biochanin-A on the proliferation of primary culture of osteoblasts isolated from the femur and on estrogen receptor positive human breast adenocarcinoma cell line MCF-7.

transportation, lack of proper storage condition in Indian situation. In India, losses of up to 40 percent of produce occur because of excessive fruit softening. Among all strategies available for minimizing the postharvest losses, genetics approach is the best way. Among genetic approaches, marker assisted breeding is the promising one as transgenic is not reasonable in India. With the objective of selecting tomato lines with high shelf life F 7 lines were derived from crosses between L121 × Vaibhav on the basis of shelf-life and fruit yield. L121 is (alc gene) showing high shelf-life; Vaibhav is having good agronomic cultivar released by the UAS Bangalore. We have obtained lines which showed high shelf-life more than 70 days and mean of F7lines were 45 days. These lines were evaluated at molecular level using SSR Markers and confirmed the presence of marker Tom184 and Tom144 which are linked to high shelf life in tomato. The tomato lines like RIL 7-3, RIL 34-2, RIL 110-2, RIL 182-4 have shown shelf life of 70 days. These lines with high shelf life can be

PP-LS-26 SCREENING OF Streptomyces Spp FOR LIPASE INHIBITORS Sukrutha Suresh, Venkata Krishna Bayineni, Gurmeet Singh and Ravi-Kumar Kadeppagari NanoBiosciences, Centre for Emerging Technologies, Jain University, Jain Global Campus, Jakkasandra post, Kanakapura Main Road, Ramanagara Dist., Karnataka, India, 562112 ABSTRACT Cases of obesity are increasing at alarming rate in our country due to the improved socioeconomic status of the people. Obesity is primarily related to the lipid metabolism and enzymes involved with this metabolism can be selectively targeted for developing antiobesity drugs. Orlistat is the only commercially available lipase inhibitor for treating obesity. However, it has adverse side effects like acute kidney injury, gastric problems and acute oxalate nephropathy. Hence there is a need for lipase inhibitors that has no or reduced side effects. One way of obtaining new inhibitors is by screening un-explored species. We have screened un-explored species of Streptomyces for lipase inhibitors since Streptomyces were shown to produce novel metabolites. The un-explored Streptomyces species like S.annulatus, S.albaduncus, S.clavifer, S.coelicolor, S.peuceticus etc. were screened for checking the lipase inhibition activity and S.abraviensis was used as a positive control while screening since it was already reported to produce lipase inhibitors, Ebelactones. The species of Streptomyces were grown on the medium containing soluble starch, glucose, soya bean meal , yeast extract, CaCO 3, NaCl, MgSO4 at 30°C and 140-150rpm for 5-7days. Biomass was separated from the medium by centrifugation and supernatant was used for estimating the extracellular lipase inhibition activity. In order to check intracellular lipase inhibition activity the biomass was macerated using appropriate volume of water and extracted by using equal volume of ethyl acetate. S. coelicolor showed lipase inhibition activity in the both extra and intracellular extracts. Inhibition activity was around 65100%. Other species didn’t show significant lipase inhibition activity.

ABSTRACT Candida species are the most common fungal pathogens isolated from the oral cavity. Their oral existence both as a commensal and an opportunist pathogen has intrigued clinicians and scientists for many decades, and recent investigations have revealed many attributes of this fungus contributing to its pathogenicity. . Many factors contribute to the development of oropharyngeal candidiasis (OPC) including malnutrition, poor oral hygiene, dental malocclusion, and immuno suppression . In addition, the advent of the human immunodeficiency virus infection and AIDS has resulted in a resurgence of oral Candida infections. Therefore, this review is an attempt at detailing the current knowledge on Candida and oral candidoses.Oral candidiasis, which is also called thrush, is a fungal infection of the mouth and/or throat. Till date, CD4 cell count and viral load are recognized and widely used as markers of HIV-related disease progression. However, laboratory parameters will only partially reflect disease stage and progression, the additional clinical marker will more accurately represent the patient’s overall disease status.Considering the individual significance of CD4 cell count and oral lesions in assessing the disease status, it was thought worthwhile to correlate the two parameters, viz. CD4 cell count and oral lesions, in HIV/AIDS patients. This study was undertaken to assess the efficacy of oral changes as an indicator of disease status in HIV/AIDS. The study included 205 subjects were used for this study. Two samples (blood and oral wash) were collected from each subject. Each specimen was processed using standard microbiological techniques and emergent Candida isolates were identified with CHROMagarTM Candida and germ tube test.

PP-LS-28 PROTECTIVE EFFECTS OF RESVERATROL AGAINST Β-ADRENERGIC AGONIST INDUCED MYOCARDIAL STRESS IN DIABETIC RATS Uma .S and Sreepriya M * *Department of Microbiology and Biotechnology, Bangalore University, Jnana Bharathi Campus, Bangalore – 560 056 ABSTRACT India is notoriously known as the diabetes capital of the world. Diabetes superimposed with macrovascular cardiac complications is the major cause of morbidity and mortality worldwide. Till today its management remains a clinical challenge and a problem of great importance. Despite understanding the mechanisms contributing to the development of cardiovascular diseases in diabetic patients, currently available conventional treatments for preventing the same are severely limited. Hence there is increased interest and renewed research focus on investigating the potential of natural products in the prevention of cardiovascular disease during diabetic conditions through novel strategies. Phytoalexins are chemcial substances produced by plants as a defensive response against infection by pathogenic microorganisms such as fungi. Resveratrol ( 3,4,5 trihydroxystilbene) is a naturally occurring phytoalexin reported to possess antidiabetic and cardioprotective The Oxford College of Science, Bangalore

Scientific studies implicating the effects of resveratrol in preventing the cardiovascular complications during diabetic conditions are lacking. Hence the present investigation was carried out to study the effects of resveratrol supplementation (5mg/kg body wt/day orally for 21 days) to combat myocardial stress induced by isoproterenol (150 mg/kg body wt single i.p) in diabetic rats. Biochemical and pathological analysis were performed to evaluate the same. In vitro studies were carried out on cardiomyocytes to complement the in vivo findings. Results confirm the protective effects of resveratrol treatment in abrogating isoproterenol-induced cardiac damage during diabetogenic conditions both in vivo and in vitro. PP-LS-29 Couroupita guianensis FLOWER EXTRACT (NAGALINGA PUSHPA): A POTENTIAL NATURAL REMEDIES FOR DENTAL CARIES Umesh R, Vijaya R, Bhanuprakash K S, and Dr. Sangita Roy. Department of Biochemistry, The Oxford College of Science, Bangalore, Karnataka. Dental caries are one of the most common chronic infectious diseases in the world. Bacterial plaque accumulated on dental surfaces and composed of native oral flora are the primary etiologic agent of dental caries. It is a major health problem and comprises 6090% children and vast majority of adult. Herbal remedies have a long history of use for gum and tooth problems such as dental caries. In vitro studies indicate that a variety of common oral bacteria are especially sensitive to the antimicrobial activities of many plant extract. Couroupita guianensis, commonly named as Cannonball tree, belong to the family Lecythidaceae is an indigenous tropical rainforest tree of South America and India. The antimicrobial, anti-inflammatory properties of the flower of Couroupita guianensis (nagalinga pushpa) have already been reported. In Ayurveda, nagalinga flower extracts were used as a pain reliever for dental diseases, but there is no such report of its role in dental caries and other periodontal diseases. This study is aimed to elucidate the function of Couroupita guianensis flower as a potential candidate for in vitro treatment of dental caries and a future natural medicine for dental caries.

All these 55 isolates were tested for resistance against 5 different metal salts i.e. Cadmium acetate, Ferrous sulfate, Mercuric chloride, Lead acetate and Zinc sulfate at 0.1% concentration. All the 55 isolates (100%) showed complete resistance to Ferrous sulfate. Similarly 51 isolates (93%) showed complete resistance to Zinc and 4 (7%) isolates showed 8 mm diameter of zone of inhibition. When resistance against Lead was checked 44 (80%) isolates showed complete resistance and 11 (20%) isolates showed 10 mm diameter of zone of inhibition. Among 55 isolates, 3 (5%) isolates showed complete resistance to Cadmium; 6 (11%) isolates showed 10 mm diameter of zone of inhibition against Cadmium, the rest 46 (84%) isolates showed diameter of zone of inhibition between 10-41 mm. Five (9%) out of 55 isolates showed 11 mm diameter of zone of inhibition against Mercuric chloride and the rest 50 (90%) isolates showed 12-40 mm diameter of zone of inhibition. The isolates JUHc1 and JUHd5 showed 10 mm diameter of zone of inhibition against Cadmium and Mercury, while complete resistance was shown against Lead, Ferrous and Zinc. Hence these two isolates have been selected for further studies. Keywords: Heavy metal, resistant, Bacteria

Rubella is normally a self limiting febrile illness without significant long term morbidity. Infection during pregnancy, may lead to miscarriage, fetal death or the birth of an infant with congenital rubella syndrome (CRS).It is estimated that worldwide more than 100 000 children with CRS are born each year.single blood sample was taken from 120 females of reproducing age (15-40) years visiting RIMS hospital over a period of one month. All the sera was examined by Sandwich enzyme linked immunosorbant assay (ELISA) for rubella specific IgG and IgM and Chemiluminescence technique and compared the techniques for its efficiency. A questionnaire was used to collect demographic data including age, sex, previous history, previous vaccination and knowledge about rubella. Among 120 females tested for rubella infection, 95 of them was found positive for rubella IgG, representing the high level of exposure to this infection. Around 43 females were positive for IgM, representing the recent infection. And 20 of pregnant females were found to be IgM positive in the first trimester and thus a high risk of CRS. This pilot study done in one month in 120 females represent most of the district of Jharkhand. It was found that the percentage of IgG positive females were more in Jharkhand compared to Delhi and Kashmir based on the article referred. This shows low immunization coverage rate in Jharkhand.

Dyeing component has been extracted from the bark of Swietenia macrophylla for its application on natural textile substrates viz., cotton, silk and wool. Color values and color co-ordinates were examined. The extracted dye showed excellent wash, rub and perspiration fastness and good light fastness on all the substrates. The dye was tested for some of the eco-parameters using atomic absorption spectrophotometer and Gas Chromatography/Mass Spectra. The test results were compared with the set standards to determine the eco-friendliness of natural dye. Their concentrations were much below than the stipulated limits. Dyed samples were also tested for antimicrobial activity against grampositive and gram-negative bacteria and are found to possess antibacterial activity. The dye may be considered as an eco-friendly alternative for dyeing natural textile fabrics. Key words: antimicrobial activity, dyeing, heavy metal, Swietenia macrophylla, textile.

ANTIDERMATOPHYTIC PROPERTIES OF TURMERIC OIL, AND CURCUMA LONGA PREPARATIONS Suhasini Badigar Department of Microbiology, the Oxford College of Collge ABSTRACT Curcuma longa L. or turmeric of the family Zingiberaceae is widely used in Thai traditional medicines for the treatment of rash, itching, tinea, and ringworm. Previous studies on turmeric oil reported effective antifungal activity against dermatophytes, a group of fungi that causes skin diseases. In this study, turmeric creams containing 6 and 10% w/w turmeric oil were prepared and tested against clinical strains of dermatophytes using broth dilution technique. Minimum fungicidal concentrations of 6 and 10% w/w turmeric creams were found to be 312 μg/mL. Ar-turmerone, a major compound separated from turmeric oil, promoted more effective antidermatophytic activity with the MICs of 1.56–6.25 μg/mL, compared to 3.90–7.81 μg/mL of standard ketoconazole. The results indicated that 6% w/w turmeric oil in the cream was suitable to be formulated as antidermatophytic preparation. Further research should be done on long-term chemical and antifungal stabilities of the preparation.
