Abrégé

The present disclosure belongs to the technical field of microorganisms, and specifically relates to a non-toxin-producing Aspergillus flavus strain, a microbial inoculant, a preparation, and use. The present disclosure provides a non-toxin-producing Aspergillus flavus strain EXY1A109 with a deposit number of CCTCC No: M20221465. The strain can effectively inhibit the production of aflatoxin B1, aflatoxin B2, aflatoxin G1, and aflatoxin G2 by a toxin-producing Aspergillus flavus strain. The results of examples show that when an Aspergillus flavus strain EXY1A109 spore suspension and a strain CGMCC 3.4408 spore suspension are mixed in an equal volume, the Aspergillus flavus strain EXY1A109 spore suspension and the strain CGMCC 3.4408 spore suspension each have a concentration of 1×106, and the strain EXY1A109 has a toxin-producing inhibition rate of 99.71% against the strain CGMCC 3.4408. This Aspergillus flavus strain shows a desirable application effect.
