Aflatoxin B1 (AFB1) is a highly toxic and carcinogenic mycotoxin that poses a serious threat to food safety and human health. This study aimed to investigate the degradation characteristics of Aflatoxin B1 (AFB1) by the laboratory-preserved strain Bacillus aerius CGMCC No.31025 and to identify its degradation products. Through various treatments of fermentation broth, studies on active components, and analysis on physicochemical properties of active substances, the primary active components of B. aerius CGMCC No.31025 degrading AFB1 were determined using high-performance liquid chromatography (HPLC). The degradation products were separated and identified via ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). Results indicated that the primary active component responsible for AFB1 degradation by B. aerius CGMCC No.31025 was the fermentation supernatant, which exhibited high thermal stability for its effective active substances. Protein inactivation treatments indicated that the active component degrading the toxin in the fermentation supernatant might be an enzyme or other active protein. UPLC-MS/MS analysis identified multiple degradation products, which were predicted to result primarily from hydroxylation, reduction and dealkylation of functional groups in the parent AFB1 structure. This study provides potential microbial strains and technical support for the biological removal of AFB1 contamination in food and feed.
