Microbial degradation is an effective and attractive method for eliminating aflatoxin B1 (AFB1), which severely toxic to humans animals. In this study, Aspergillus niger RAF106 could effectively degrade AFB1 when cultivated in Sabouraud dextrose broth (SDB) with contents of ranging from 0.1 4 μg/mL. Treatment yeast extract as a nitrogen source stimulated the degradation, but treatment NaNO3 NaNO2 sources lactose sucrose carbon suppressed degradation. Moreover, A. still degraded at initial pH...
Although (−)-epigallocatechin-3-gallate (EGCG) exhibits various bioactivities, its low bioavailability and toxicity at high concentrations limit application. Microbial biotransformation of EGCG could improve but the interplay between EGCG-transforming microbes was little known. Here, 50 g/L or less completely degraded 48 h when co-incubated with Aspergillus niger RAF106 in potato dextrose broth. The degradation accompanied by an unchanged radical-scavenging activity increase production...
Biotransformation of green tea catechins mediated by microbes and/or enzymes could increase their bioavailability and improve health benefits, but the regulatory mechanism remains unclear. Here, Aspergillus niger RAF106 isolated from Pu-erh was proved to be capable degrading gradually ester-catechins into non-ester-catechins with higher gallic acid (GA) in aqueous solution only containing catechins, products displayed similar radical-scavenging activity vitro control. Meanwhile, degradation...
