摘　　要：全世界约25%的谷物供应受真菌毒素污染,给食品和饲料工业带来巨大经济损失,严重威胁着人类健康。因此,如何高效去除黄曲霉毒素(aflatoxin,AF)成为当今亟待解决的重大问题。生物法由于具有无污染、特异性高、温和、环保等特点被广泛关注。该文对生物法降解AF进行了阐述,重点介绍了微生物和昆虫对AFB1的降解作用,并从降解酶、挥发性有机化合物及AFB1生物合成相关基因的表达论述了AFB1的降解机制,展望了生物法降解AFB1的存在问题及应用前景,为后续生物法降解AF提供理论依据。About 25%cereals in the world are contaminated with mycotoxins produced by variety of toxigenic fungi,which has brought huge economic losses to the development of food and feed industry,and even threatened human health.Therefore,how to remove effectively aflatoxin(AF)has become an urgent problem to be solved in the world.Recently,the biological method has been widely concerned because of its characteristics of pollution-free,high specificity,mild and environmental protection.This review focuses on the degradation of AFB1 by microorganisms and insects,and the degradation mechanism of AFB1 from degradation enzymes,volatile organic compounds and the expression of biosynthesis related genes is also elaborated.The existing problems and application prospects of biodegradation of AFB1 are prospected,providing theoretical basis for the subsequent biodegradation of AFB1.
