Beschreibung
Zusammenfassung:	The invention relates to a bacillus subtilis ANSB01G CGMCC No. 4297 for simultaneously degrading zearalenone and cellulose and a culturing method thereof. The invention also relates to a method for degrading the zearalenone and the cellulose by using a fermentation liquor of a bacterial strain; by using the method, the degradation rate of the zearalenone can reach 83% while the zearalenone reactswith the bacillus subtilis for 72 hours; and the enzyme activity of the cellulose of the fermentation liquor of the bacillus subtilis is 198.9 U/g. The bacillus subtilis provided by the invention hasthe advantages of high activity, strong specificity, mild action effect and no damage to nutrition constituents in a feed during degrading the zearalenone; moreover, by using the bacillus subtilis, the cellulose can be also degraded to increase the feed conversion rate.
