Bacillus cereus, also known as cactus, is a gram-positive bacterium and a β -hemolytic rod-shaped bacterium. Often found in soil and food, some strains can cause food poisoning; Other strains are beneficial to other animals. Bacillus cereus is facultative anaerobic. Like other Bacillus, it produces defensive endospore.
The cell morphology and arrangement of Bacillus licheniformis are rod-shaped and solitary, which can regulate flora imbalance to achieve therapeutic purposes, promote the body to produce antibacterial active substances and kill pathogenic bacteria. Can produce anti-active substances, has a unique biological hypoxia mechanism, and can inhibit the growth and reproduction of pathogenic bacteria.
2, the effect is different
After Bacillus cereus enters the intestine, it consumes too much oxygen in the intestine, creating an anaerobic environment, promoting the growth of anaerobic bacteria, adjusting the imbalance of intestinal flora, improving the microecological environment, and achieving the purpose of being suitable for the survival of beneficial anaerobic bacteria and inhibiting harmful aerobic bacteria.
After entering the intestine, Bacillus licheniformis has antagonistic effect on staphylococcus, yeast-like bacteria and other pathogenic bacteria, but it has promoting effect on Bifidobacterium, Lactobacillus, Bacteroides and Streptococcus pepticus, thus regulating flora imbalance and achieving the purpose of treatment. At the same time, it can promote the body to produce antibacterial active substances and kill pathogenic bacteria. In addition, the biological effect of hypoxia is beneficial to the growth of anaerobic bacteria.
3. Different applicable objects
Bacillus licheniformis is suitable for intestinal flora imbalance caused by bacteria that need health care and cultured animals. It has obvious effect on poultry animals such as chicken, duck and goose. Bacillus subtilis prepared by pigs, cattle, sheep and other animals has better use effect.
Bacillus cereus can produce antibacterial substances, inhibit the reproduction of harmful microorganisms, degrade nutrients in the soil and improve the ecological environment. Can produce bacterial protease; It can be used for degumming hemp and is a bacterium to measure the antibacterial activity of various antibiotics. It can be used for gelatin liquefaction, milk peptization, nitrate reduction and starch hydrolysis.
