Problems solved by technology

However, the generation time of these probiotic strains of lactic acid bacteria is about 40-60 minutes, such as the most common Lactobacillus, etc., the generation time is longer, and the competition ability with pathogenic bacteria in the intestinal tract is not strong; the lactic acid produced by Lactobacillus 50% is L-type lactic acid and 50% is D-type lactic acid. L-type lactic acid is also called natural lactic acid, which can be absorbed and utilized by animals, while D-type lactic acid can only be absorbed but not utilized. Therefore, the absorbed D-type lactic acid The energy will be wasted; among the three probiotic strains, spores are the most stable in a dry environment and are not easily affected by the external environment, while the stability of lactic acid bacteria and yeast is much worse, and special methods must be used to protect them. to improve its stability

Embodiment Construction

[0008] The Enterococcus faecium of the invention is spherical or oval, arranged in chains, and has no spores. No flagella. In the early stage of culture (2~4h), a capsule of hyaluronic acid is formed, with pili, containing type-specific M protein. Easily stained by common basic dyes, Gram stain positive. The cultivation requirements are high, and blood, serum, glucose, etc. need to be supplemented. It is easy to form long chains in serum broth, and a flocculent precipitate is formed at the bottom of the tube. On the blood agar plate, different strains showed different hemolysis.

[0009] Biochemical characteristics: Enterococcus faecium decomposes glucose, produces acid but not gas, and is not dissolved by bile.

[0010] The following tests illustrate the benefits of Enterococcus faecium as a feed additive:

[0011] (1) Enterococcus faecium of the present invention can produce fungicides: when Enterococcus faecium and Escherichia coli are mixed and cultured in test tubes,...

Abstract

The invention relates to enterococcus faecium Anp01 belonging to enterococcus. The enterococcus faecium Anp01 is preserved in China Center for Type Culture Collection (CCTCC) on January 19th, 2009, and the preservation NO is M209019. The enterococcus faecium Anp01 is used as a feed additive for improving the organism immunity. The enterococcus faecium Anp01 (CCTCC M209019) belongs to normal intestinal bacteria having no toxicity and intestinal pathogenicity to human beings and animals. The feed additive prepared by using the enterococcus faecium Anp01 can not generate any toxin even under abnormal conditions, can not generate potential hazards when the immunity function of host animals is low, and is a pure natural feed additive without any external drug resistance.

Description

technical field [0001] The invention relates to an Enterococcus faecium Anp01 (Enterococcus faecium Anp01) of the genus Enterococcus, which was preserved in the China Type Culture Collection Center on January 19, 2009, CCTCC NO: M209019, which is used as a feed additive to improve body immunity. Background technique [0002] With the development of science and technology, people pay more and more attention to the improvement of the body's immunity. As a preparation that can significantly improve the body's immune function, probiotics have received widespread attention and active research from international medical institutions. Probiotics are also a good feed additive, and can act as an immune activator, stimulating animals to produce interferon, increasing the concentration of immunoglobulin and the activity of macrophages, stimulating Enhancement of the body's immunity. After oral administration of probiotics to animals, the composition of the intestinal flora can be adj...
