What is Enterococcus faecalis?
what is enterococcus faecalis?
Enterococcus faecalis is a facultative anaerobic lactic acid bacteria. The "Catalogue of Feed Additives (2013)" defines Enterococcus faecalis as a bacterial species that can be added to the feed. It can form a biofilm in the animal intestine and attach to the animal intestine. mucosa, and develop, grow and reproduce. Enterococcus faecalis can soften the fiber in the feed and improve the conversion rate of the feed. Some scholars have found that adding Enterococcus faecalis and cellulase to corn stalk silage can significantly improve the color, odor and texture of silage, increase the dry matter disappearance rate by 8%, and increase ammonia nitrogen and total nitrogen. The mass ratio was reduced by 33%, the mass fraction of butyric acid was reduced by 82%, and the contents of neutral detergent fiber and acid detergent fiber were decreased by 10% and 7% respectively, which significantly improved the feed quality.
Enterococcus faecalis can produce a variety of antibacterial substances, which have a good inhibitory effect on pathogenic bacteria such as Salmonella, Escherichia coli and Staphylococcus aureus. Studies have shown that Enterococcus faecalis can produce volgamycin, which can effectively inhibit the growth and reproduction of Listeria and Staphylococcus aureus and spoilage microorganisms.
Enterococcus faecalis can tolerate low pH, and has high tolerance to gastric juice, intestinal juice, and bile salts. Enterococcus faecalis can proliferate in large quantities after entering the intestinal tract, inhibit the growth of harmful microorganisms, regulate the intestinal microecological balance, and reduce the occurrence of intestinal diseases.
Enterococcus faecalis can increase the activity of digestive enzymes such as protease, amylase, lipase and cellulase in the digestive tract of animals. These enzymes can promote the decomposition of protein, fat and complex carbohydrates in the feed, and finally generate monomers and energy. Supply the growth and development of the body, thereby improving the digestion and absorption rate of feed and promoting the growth of animals;
Enterococcus faecalis also produces vitamins, amino acids, growth-promoting factors and other nutrients during the growth and reproduction process, which promotes the absorption of iron, calcium, zinc and other mineral elements, and supplements the body’s nutritional elements; The fiber softens and improves the feed conversion rate. Enterococcus can improve the immunity of animals and enhance their ability to resist pathogenic infection.
Enterococcus faecalis can form a biofilm in the animal intestine and attach to the animal intestinal mucosa, and develop, grow and reproduce to form a lactic acid bacteria barrier to resist the invasion of foreign bacteria, viruses, mycotoxins and other harmful substances, and has an immune barrier effect.
Enterococcus faecalis is prepared into a microbial preparation, which can be directly fed to breeding animals, which is beneficial to improve the microecological balance in the intestinal tract and prevent the intestinal flora flora disorder of animals. Decompose protein into small peptides, synthesize B vitamins, etc. Enterococcus faecalis can also enhance the activity of macrophages, promote the immune response of animals, and increase antibody levels. Enterococcus faecalis can form a biofilm in the animal intestine and attach to the animal intestinal mucosa, and develop, grow and reproduce, and can form a lactic acid bacteria barrier to resist the side effects of foreign bacteria, viruses and mycotoxins, while Bacillus and yeast, etc. They are all passing bacteria and do not have this function.
Enterococcus faecalis can decompose some proteins into amides and amino acids, and convert most of the nitrogen-free extracts of carbohydrates into L-type lactic acid. Enterococcus faecalis can also soften the fiber in the feed and improve the conversion rate of the feed. Enterococcus faecalis can produce a variety of antibacterial substances, and these antibacterial substances have a good inhibitory effect on common pathogenic bacteria in animals.
