Bacillus coagulans (Bacillus coagulans) rod-shaped, rounded at both ends, was Gram-positive bacteria, catalase-positive, spore-side life, no flagella. The optimum growth temperature is 45 ~ 50 ℃, the optimum pH value of 6.6 to 7.0. Which can break down carbohydrates to generate L- lactic acid, a lactic acid bacteria, spores of known lactic acid bacteria, lactic acid bacteria are capable of sporulation. Bacillus coagulans addition to Lactobacillus and Bifidobacterium and the same health benefits, but also with acid, heat, salt, easy to cultivate and preserve the characteristics of the US Food and Drug Administration (FDA) and the Association of American Feed Control Officials column microorganisms can be used to secure the feed list. Bacillus coagulans by 90 ℃, 60min heat treatment and 120 ℃, 60min dry heat, its viable count fell by only one order of magnitude; placing acidic solution pH greater than 2.42, the store a year later, the survival rate is still up to 105; Bacillus coagulans in 1% ~ 7% NaCl solution can survive 4 Week or more, its 8% NaCl solution can survive a month. However, Bacillus coagulans at low pH conditions, its resistance will decrease. For example, under acidic conditions (pH4.0), Bacillus coagulans spores little heat tolerance, and growth was inhibited. Bacillus coagulans spores orally into the stomach, in the gastric environment begin germination and growth, spore coat expansion increases spore shape, increasing the water content, the spores from clothes to grow protrusions. When entering the duodenum, the spores have germinated vegetative cells, and then into the small intestine, and began large population doubling time of 30min. ;
Bacillus coagulans physiological functions following main points:
(1) Bacillus coagulans facultative anaerobes, will consume free oxygen into the intestinal tract and intestinal breeding beneficial anaerobic lactic acid bacteria and bifidobacteria growth, thereby regulating the balance of flora in the gut microflora improve the body's immunity and resistance to disease, reduce the incidence of intestinal diseases.（2) Bacillus coagulans reproduction in the gut secrete amylases and proteases, help digestion and absorption of nutrients; which produces a vitamin, amino acid, short chain fatty acids and other substances capable of increasing the speed of intestinal motility, improve digestive function, promote digestion and absorption of feed, lower feed conversion. Lactic acid (3) Bacillus coagulans produced antimicrobial coagulin and a variety of enzymes can inhibit harmful bacteria, there is catharsis, diarrhea, effectively improve weaning due to stress, allergic reactions caused by diarrhea flora. (4) without any side effects, safe to use, in addition to Bacillus coagulans in the metabolic process to produce antibacterial substances - coagulation factors, inflammation of the gastrointestinal tract and therefore have a therapeutic effect
