Abstract

The invention relates to enterococcus faecium for feeding as well as a freeze-drying fungicide and applications thereof, and discloses enterococcus faecium LAB12 CGMCC (China General Microbiological Culture Collection Center) No.4847 which is grampositive cocci, has no spores, grows well on an MRS agar plate, forms a round bacterial colony with the diameter of 0.5-1mm within 48 hours and is used for feeding, and the bacterial colony is round, smooth and upheaved, and is a shape of grey white dewdrop; the enterococcus faecium grows in a facultative anaerobic condition; the growth temperature range is 10 DEG C-45 DEG C; the optimum growth temperature is 30 DEG C-40 DEG C; and the growth pH value is 4-10, and the optimum pH value is 6.0. The freeze-drying fungicide formed by the bacterial strain is nontoxic and harmless, is gastric juice resistant, is cholate resistant, has a high inhibitory effect for multiple harmful bacteria, has a long quality guarantee period, can be widely applied to birds and livestock breeding to strengthen the animal disease-resistant capability, and is expected to be the substitution of antibiotics for feeding.

Description

technical field

[0001] The invention belongs to microbial strains, in particular to an Enterococcus faecium strain and its freeze-dried bacterial preparation and its application in the preparation of feed and feed additives. Background technique

[0002] Enterococcus faecium belongs to the genus Enterococcus and is part of the normal flora in the intestinal tract of humans and animals. Enterococcus faecium has strong adhesion to the intestinal mucosa of animals, and can form a protective physiological barrier on the intestinal mucosa of animals to prevent the colonization and invasion of pathogenic bacteria. Enterococcus faecium can also produce vitamins, amino acids, growth-promoting factors, lactic acid and acetic acid and other nutrients needed for animal growth; at the same time, it can produce lactosin, idamicin, acidophilus and bacitracin to inhibit the growth of pathogenic bacteria reproductive substance. As a feed probiotic, Enterococcus faecium can be applied to a...
