Mass spectral analysis of Lac 2-mediated aflatoxin B1 degradation. NSI-MS experiments were performed using a Full MS in the positive ion mode. (A) Lac 2-mediated AFB1 degradation process over a period of 60 h. Samples were periodically taken for UHPLC-MS/MS. AFB1 and the product at the retention time of 5.349 min and 3.913 min, respectively. (B) Mass spectrum of AFB1 (C17H12O6). (C) Mass spectrum of the product from Lac 2-mediated AFB1 degradation (C17H12O7).
