Characterization and mechanism of simultaneous degradation of aflatoxin B₁ and zearalenone by an edible fungus of Agrocybe cylindracea GC-Ac2.

ABSTRACT: Contamination with multiple mycotoxins is a major issue for global food safety and trade. This study focused on the degradation of aflatoxin B₁ (AFB₁) and zearalenone (ZEN) by 8 types of edible fungi belonging to 6 species, inclulding Agaricus bisporus, Agrocybe cylindracea, Cyclocybe cylindracea, Cyclocybe aegerita, Hypsizygus marmoreus and Lentinula edodes. Among these fungi, Agrocybe cylindracea strain GC-Ac2 was shown to be the most efficient in the degradation of AFB₁ and ZEN. Under optimal degradation conditions (pH 6.0 and 37.4°C for 37.9 h), the degradation rate of both AFB₁ and ZEN reached over 96%. Through the analysis of functional detoxification components, it was found that the removal
