Description

technical field

[0001] The invention belongs to the field of microorganisms, and in particular relates to a biocontrol strain of Serratia marcescens which can efficiently inhibit the synthesis of aflatoxin by Aspergillus flavus and its application. Background technique

[0002] Aspergillus flavus is a pathogenic fungus that can produce a class of strong carcinogenic and highly toxic mycotoxins - aflatoxins, including B, G and M groups, of which B1 is the most common and the most toxic. It can widely pollute peanuts, corn and other food crops, seriously threaten the health of people and livestock, and cause great economic losses. Therefore, it is urgent to strengthen the prevention and control of Aspergillus flavus and toxin pollution.

[0003] At present, in the control of Aspergillus flavus, there are three control methods: physical, chemical and biological. However, chemical control is not only costly, but also easy to pollute the environment. While preventing and contro...
