The invention discloses a cellulosimicrobium funkei stain SLAQ001. The cellulosimicrobium funkei stain SLAQ001 is preserved in China Center for Type Culture Collection (CCTCC) and the preservation number is CCTCC NO:M2013564. The invention further discloses an application of the cellulosimicrobium funkei stain SLAQ001 to degrading aflatoxin B1. The cellulosimicrobium funkei stain SLAQ001 has a very good degradation capability on the aflatoxin B1 and can resist a gastrointestinal tract environment of an animal body to express the detoxification effect in the animal body, so that the cellulosimicrobium funkei stain SLAQ001 is suitable for removing the aflatoxin B1 in the production of an animal husbandry. The cellulosimicrobium funkei stain can be used for drenching poultries and is used for reducing the toxin on the poultries by the aflatoxin B1 and remitting the damages, caused by the aflatoxin B1, to livers of the poultries.
