Coumarin was used for primary screening of AFB1 degrading bacteria.
The culture supernatant of Bacillus licheniformis CFR1 had the better AFB1 degrading ability.
The degraded products were different from AFB1 chemically and lost its fluorescence and mutagenic properties.
B. licheniformis CFR1 might be an excellent candidate for bioremediation and detoxification of AFB1.
