Abstract

The invention discloses a bacillus siamensis WF2019 strain for degrading aflatoxin B1 and an application of the bacillus siamensis WF2019 strain. The bacillus siamensis WF2019 strain capable of efficiently degrading the aflatoxin B1 is successfully separated and obtained, is preserved in Guangdong Microbial Culture Collection Center on June 18th, 2019, and has preservation number of GDMCC NO:60700. The strain can efficiently degrade the aflatoxin B1, and the degradation rate is as high as 98.9%; the environment adaptability is good, the high-temperature resistance is remarkable, and the degradation performance is still remarkable at the temperature of 60 DEG C; meanwhile, fermentation liquor or intracellular substances of the strain can also degrade the aflatoxin B1 and can be applied to detoxification of agricultural products polluted by the aflatoxin B1; in addition, the strain is pollution-free and nuisanceless in the using process. Therefore, the strain is an ideal agricultural product detoxification microorganism, and has good promotion and application prospects in the detoxification aspect of the aflatoxin B1 in the field of feed processing or food processing.

Description

technical field

[0001] The invention belongs to the technical field of aflatoxin detoxification. More specifically, it relates to a Bacillus siamese WF2019 strain for degrading aflatoxin B1 and its application. Background technique

[0002] Aflatoxin B1 (AFB1) is mainly a mycotoxin produced by Aspergillus parasiticus and Aspergillus flavus, and is currently the most toxic, teratogenic and carcinogenic mycotoxin. At present, AFB1 pollution widely exists in various agricultural products, such as grain crops, food, feed, etc., causing huge economic losses and seriously threatening the health of humans and livestock. In my country, AFB1 pollution is very serious. From January 2015 to April 2019, there were 646 incidents of food mycotoxins exceeding the standard reported in my country, of which AFB1 exceeded the standard incidents accounted for 71%; Toxins accounted for 29.04%, of which AFB1 exceeded the standard events accounted for 97.53%. It can be seen that it is urgent to ...
