Beschreibung
Zusammenfassung:	The invention relates to a Bacillus subtilis ANSB 060CGMCC No.3440 used for degrading aflatoxins, and culture method and application thereof. The invention also provides a method for degrading aflatoxins B1, G1 and M1 by fermentation liquor of the strain. By the method, the Bacillus subtilis is reacted with the aflatoxin B1 for 2 hours, has a degradation rate of over 70 percent on the aflatoxin B1, and has the degradation rate of over 80 percent after the reaction performed for 12 hours; and the Bacillus subtilis has the degradation rates of over 80 percent and over 60 percent on the aflatoxin G1 and aflatoxin M1 respectively. The Bacillus subtilis has high detoxification activity, strong specificity, mild action effect, and no damage to nutrient in feeds, and is suitable for removing theaflatoxins in the feeds.
