Feed Additive

Clostridium butyricum also known as butyricicoccus, Clostridium butyricum, butyricicoccus. Was first discovered and reported in 1933 by Dr. Miyazaki, Chiba Medical University, Japan, and is therefore also known as Miyazawa. Taxonomically assigned to the genus Clostridium as a gram positive anaerobe. In 1935, Dr. kingi miyairi, Russian Institute of Microbiology, isolated Clostridium butyricum from human feces and soil, and subsequently found that its anaerobic cultured filtrate contained less fatty acids and had an extremely strong whole gut effect, which inhibited pathogenic bacteria in the gut and promoted the growth of beneficial bacteria such as Bifidobacterium and Lactobacillus in the gut, Clostridium butyricum was introduced and colonized in China by the Russian Institute of Microbiology, Institute of Microbiology, Heilongjiang Academy of Sciences in 1992, making a significant contribution to the development of microbial beneficial bacteria in China.

Lactobacillus acidophilus belongs to an important class of members in the family of lactic acid bacteria, gram-positive, non bacillus, and its morphology is in the form of chain rod or ball rod, and its optimal growth temperature is 37-42 ◦ C, and its optimal pH is 6.8. L. acidophilus as early as the 1970s, North Carolina State University first isolated the lactobacillusacidophilusncfm from human feces, and it was the only strain of L. acidophilus that had been genetically sequenced and annotated. L. acidophilus, one of the widely studied and developed probiotics in the current lactic acid bacteria family, is regarded as the third-generation acid milk starter species and an important microorganism in the human body. L. acidophilus is not only in the stomach, it is also the main probiotic in the small intestine of humans.

Lactobacillus plantarum, as one of the probiotics released by the Ministry of health, can effectively tolerate the human digestive system, survive in large quantities in the intestine, regulate the balance of intestinal flora and promote human digestion and absorption; At the same time, Lactobacillus plantarum also has prebiotic and health care functions such as reducing cholesterol, preventing cardiovascular diseases, controlling body weight, enhancing human immunity, preventing cancer and inhibiting tumor growth.

Bacillus lateralis feed additive strain is a natural strain approved by the microbial testing center of the Ministry of agriculture. It has the characteristics of rapid reproduction, strong vitality, safety and non toxicity. Bacillus lateralis belongs to the genus Bacillus. Gram staining is positive and can be negative. The spores are oval, lateral, mesophytic or near mesophytic. The sporangium is expanded, and one side of the free spore is thicker than the other side (canoe shape). aerobic bacteria. Protein, various sugars and starch can be used to decompose tryptophan to form indole. This product can also be used in aquaculture. Lateral spores have a strong inhibitory effect on Vibrio, Escherichia coli, rod and other harmful bacteria in aquaculture; It can decompose the residual bait, feces, organic matter, water quality, and improve the turbidity problem caused by harmful cyanobacteria flooding.

Bacillus subtilis belongs to the genus Bacillus. It is a kind of Gram-positive bacteria with thermophilic, aerobic and endogenous stress resistant spores. It is widely distributed in soil and rotten organic matter. As a typical representative of Gram-positive bacteria, the research on its physiology, biochemistry, genetics and molecular biology has a history of more than 50 years. Bacillus subtilis is one of the commonly used host bacteria in transgenic technology. Other commonly used host bacteria include Escherichia coli, yeast and Agrobacterium. Bacillus subtilis is also a probiotic, which has been applied in many fields as a probiotic. In the food industry, Bacillus subtilis can be used as a fermentation strain of food products because it can produce antibiotics with certain antibacterial effect in the growth process of , and studies have proved that Bacillus subtilis does not produce substances harmful to human body; In agriculture, Bacillus subtilis has been widely used as an effective biocontrol bacterium, which can not only inhibit the growth of pathogens, but also promote the increase of crop yield; At present, Bacillus subtilis can also be used in feed, medicine (new drug or antigen delivery system), aquaculture, washing, textile and leather industries. Bacillus subtilis can also be used as a micro ecological agent in a variety of fields.
