One. Morphological characteristics of bacterial genera Bacillus families, for Gram-positive bacteria, cell size 0.8μm × (1.5 ~ 3.5) μm: cell morphology and arrangement of rod-shaped, solitary. Intracellular free poly -β- hydroxybutyrate (PHB) granules, spores in raw form for nearly oval, slightly swollen cysts. Cultural characteristics: colonies on broth was flat, jagged, white, rough surface folds, 24h after the colony diameter of 3mm. II. 1. governance mechanism bacteria bacteria, pathogenic microorganisms antagonistic Viable into the intestine, staphylococcus, yeast-like bacteria pathogen antagonism, while Bifidobacterium, Lactobacillus, Bacteroides, digestive chain promote the growth of cocci, and thus adjust the flora therapeutic purposes. 2. encourage the body to produce antimicrobial substances to kill pathogens. 3. Biological Bacillus wins oxygen for aerobic bacteria, in the growth process requires a lot of oxygen, into the animal intestines, consume a large amount of free oxygen, this oxygen wins biological effects intestinal hypoxia, advantageous for mass anaerobic growth of bacteria, resulting in intestinal hypoxia, intestinal Bifidobacterium, Lactobacillus, Bacteroides, anaerobic digestion Streptococcus healthy growth and reproduction promoted; Staphylococcus aureus, Candida albicans, yeast pathogens like bacteria there antagonism. Through this dual role intestinal flora can be adjusted to maintain the body's intestinal microflora balance, and thus achieve bowel disease treatment and prevention purposes. Third, the quality criteria 1. Ingredients: Bacillus carrier (corn, wheat bran, calcium carbonate, proteins) 2. Product Features: pure strain, strain energy is strong, high temperature, acid, breed quickly, adaptable. 3. Technical indicators as follows: Bacillus effective viable count (one hundred million / g) 300 200 100 bacteria ≤2% rate product fineness Bacillus rate ≥98% ≥60 mesh product moisture ≤8% four. A major role in promoting the normal physiology of intestinal anaerobic growth, adjust the intestinal flora and restore bowel function; 2, have effects on intestinal bacterial infections, acute enteritis for light or heavy, light and general type of , have a significant effect of acute dysentery; 3, can produce anti-active substances, and has a unique mechanism of action of biological oxygen wins, can inhibit the growth of pathogenic bacteria to multiply. . Five. Consumption usage 25kg / bag, kraft paper bag; store in a cool dry place, shelf life of 18 months. As soon as possible after opening, with the need to tie the bags back, pay attention to moisture.
