Abstract

Disclosed are a lactic acid bacterium and application thereof. The lactic acid bacterium is capable of suppressing growth of mildew in fermented feed, reducing the content of aflatoxin B1 and improving the quality of the fermented feed. The technical scheme includes that the lactic acid bacterium is lactobacillus plantarum M-9 which is preserved in the China General Microbiological Culture Collection Center on 29th October, 2012, and the preservation number of the lactobacillus plantarum M-9 is CGMCC No.6740. The invention further discloses a method for preparing and using the lactic acid bacterium.

Description

technical field [0001] The invention relates to a lactic acid bacterium for fermented feed, in particular to a lactic acid bacterium for reducing aflatoxin B1 in fermented feed which can inhibit the growth of mold in fermented feed, reduce the content of aflatoxin and improve the quality of fermented feed and its application. Background technique [0002] Aflatoxin (Aflatoxin, AFT) is a kind of fungal secondary metabolites with similar structure and physical and chemical properties, which are B1, B2, G1, G2, M1 and M2, etc. Among all aflatoxins, B1 is the most toxic And the chemical properties are the most stable, it has strong carcinogenicity, mutagenicity and teratogenicity, and is an internationally recognized class A carcinogen. Aflatoxins can be produced during crop growth, feed processing, storage and transportation. Feed mold and the resulting toxin poisoning are common problems worldwide. Experiments have shown that after animals ingest AFB1, aflatoxin B1 and its me...
