Application of loigolactobacillus coryniformis subsp.coryniformis in efficient degradation of aflatoxin

Abstract

The present disclosure discloses an application of Loigolactobacillus coryniformis subsp. coryniformis in the efficient degradation of aflatoxin. The method is as follows: Loigolactobacillus coryniformis subsp. coryniformis 523L5 is inoculated into LB broth containing Aflatoxin B1, and Aflatoxin B1 is degraded by dark reaction at 25-55° C. and pH 3.0-9.0. The Loigolactobacillus coryniformis subsp. coryniformis 523L5 has good growth performance, high acid production ability, strong salt tolerance and acid tolerance, and may tolerate about 7% salinity. It may grow under the condition of pH 4.5 and has good fermentation performance. The fermentation broth can efficiently degrade Aflatoxin B1 under acidic (pH 5.0-7.0) and high temperature (50-55° C.) conditions, and the highest degradation rate can reach 88.13% at 40° C. and pH 7.0.
