Biological Degradation of Aflatoxin B₁ by Cell-Free Extracts of Bacillus velezensis DY3108 with Broad PH Stability and Excellent Thermostability.

ABSTRACT: (1) Background: Aflatoxin contamination in food and grain poses serious problems both for economic development and public health protection, thus leading to a focus on an effective approach to control it; (2) Methods: Aflatoxin B₁ (AFB₁) degrading bacteria were isolated using a medium containing coumarin as the sole carbon source, and the biodegradation of AFB₁ by the isolate was examined by high performance liquid chromatography, and liquid chromatography mass spectrometry; (3) Results: a bacterial strain exhibiting strong AFB₁ degradation activity (91.5%) was isolated and identified as Bacillusvelezensis DY3108. The AFB₁ degrading activity was predominantly attributed to the cell-free supernatant of strain DY3108. Besides, it was heat-stable and resistant to prot
