Beschreibung
Zusammenfassung:	The invention discloses Bacillus subtilis for efficiently degrading aflatoxin and application thereof, and belongs to the field of biotechnology. The Bacillus subtilis is named ASAG212, and was preserved in the China General Microbiological Culture Collection Center with the preservation number of CGMCC No. 18367. The optimum degradation conditions are as follows: the initial concentration of Bacillus subtilis is 109 CFU/mL, the pH value is 7.2-7.6, the culture temperature is 35-40 DEG C, and the rotational speed is 120 rpm-180 rpm. 10 ug/mL of aflatoxin B1 is degrade into a non-toxic productwithin 4 hours by the strain of the invention, and the degradation rate reaches more than 90%. The invention also provides a bacterial preparation containing the strain and for degrading aflatoxin andan application of the bacterial preparation. The preparation method of the bacterial preparation used by the invention is simple, and the bacterial preparation does not contain antibiotic components,has no toxic or side effec
