Lactobacillus plantarum HEW-A490 and application thereof

Abstract

The invention provides newly-separated Lactobacillus plantarum HEW-A490. The Lactobacillus plantarum HEW-A490 has the advantages that the Lactobacillus plantarum HEW-A490 is evident in probiotic performance and stress resistance, the probiotics prepared by the Lactobacillus plantarum HEW-A490 can fast activate and proliferate after entering the intestines of animals and can form a beneficial dominant bacterial community to maintain intestinal track balance, animal feed utilization efficiency can be increased, cost can be saved, the steady state of the digestive tract internal environments in the animals is improved, nutrition absorption is promoted, animal growth is promoted, economic benefits are increased, the Lactobacillus plantarum HEW-A490 is promising in application prospect, and the like.

Description

technical field

[0001] The invention relates to probiotics for animal husbandry, in particular to a strain of Lactobacillus plantarum HEW-A490 and its application. Background technique

[0002] Lactobacillus plantarum (Lactobacillus plantarum) is a normal intestinal flora of humans and animals, widely present in traditional fermented foods. Many studies have proved that Lactobacillus plantarum can inhibit the growth and reproduction of pathogenic bacteria, promote the body's digestion and absorption of nutrients, and improve the body's Immunity and other aspects have important biological functions. Lactobacillus plantarum inhibits the growth of pathogenic bacteria by competing with the ability of pathogenic bacteria to limit nutrients, regulates the composition of intestinal microecology, and forms a biological barrier. At the same time, through the effects of the metabolites lactic acid, bacteriocin, and diacetyl produced by its metabolism on other bacteria, adjust the rel...
