چکیده انگلیسی
Four products were identified by liquid chromatography/time-of-flight mass spectrometry (LC/TOF-MS) for the degradation of aflatoxin B1 (AFB1) is by salt tolerant Candida versatilis CGMCC 3790 (C. versatilis CGMCC 3790), includingâ
¡(C14H10O4), â
¢ (C14H12O3), â
£ (C13H12O2), â
¤ (C11H10O4), which were not toxic. Based on these products, it is speculated that AFB1 degradation has two pathways. The degradation ratio of active cell component (69.40%) and intracellular component (64.99%) was significantly higher than extracellular component (29.61%), suggesting that the AFB1 removal mainly resulted from biodegradation. The optimal degradation conditions of AFB1 (20â¯ng/mL) were: incubated at pH 5.0, 25â¯Â°C for 60â¯min in liquid medium system. The degradation ratio was ranged from 41.23%â¼100% at 10.26â¼130.44â¯ng/g in an actual system. This is the first report revealing that a salt tolerant yeast could effectively degrade AFB1. Therefore, Candida versatilis CGMCC 3790 might be an excellent candidate for bioremediation and detoxification for oriental fermentation condiment process.
