What Is A Bacteria

1. What is a bacteria? Bacteria are unicellular microorganisms that have a size of some micrometers in length (between 0.5 and 5 mm, usually) and various forms, including spheres, rods and propellers. Bacteria are prokaryotes, and therefore, unlike eukaryotic cells (animals, plants, etc.), have no nucleus or internal organelles. Generally have a cell wall composed of peptidoglycan. Many bacteria have flagella or other systems of movement and are mobile. The study of bacteria is responsible bacteriology, a branch of microbiology. Bacteria are the most abundant organisms on the planet. Are ubiquitous, found in all habitats on earth, growing in soil, acidic hot springs. Around the world are using antibiotics to treat bacterial infections. Antibiotics are effective against bacteria and to inhibit the formation of the cell wall or stop other processes in its life cycle. They are also used extensively in agriculture and livestock in the absence of disease, which causes is widespread bacterial resistance to antibiotics. In industry, bacteria are important in processes such as wastewater treatment, production of cheese, yogurt, butter, vinegar, etc., and in the manufacture of drugs and other chemicals.

2. What kind of bacteria is “Lactobacillus casei “? Probiotic bacteria Lactobacillus casei, Lactobacillus genus of anaerobic microorganism that is found in the gut and in the mouth. It is a producer of lactic acid bacteria are used in the dairy industry in the development of probiotic dairy foods (containing live microorganisms that exert important physiological effects if taken in adequate amounts). This particular strain of lactobacillus was found to be very resistant to very broad ranges of pH and temperature, is also a complement to the growth L. acidophilus, a producer of the enzyme amylase (a digestive enzyme-carbohydrate in milk). It is known that improves digestion, tolerance to milk and prevents diarrhea. [1] For this reason it is used in the preparation of various functional foods. Effects on the body: The bacteria must resist the action of gastric juice, bile and duodenal and reach the intestinal tract intact where they develop immunomodulatory actions. Experiments were performed to detect these bacteria survive passage through the intestinal tract and has been seen that there is a high percentage of survival. Other studies have shown that consumption of milk with these bacteria does not change the system of immunoprotective consumers.
