摘　　要：脱氧雪腐镰刀菌烯醇(DON)作为分布最为广泛的镰刀菌毒素之一,不但给全球粮食产业造成巨大损失,而且也严重威胁食品安全,利用微生物代谢来降解原料中DON已成为目前研究的热点。本文主要介绍现已发现的生物降解、转化与吸收途径,包括3C—OH氧化、开环氧化、水合作用、糖苷化、3C-异构化、结合与吸收等作用机制,以期从原理上了解DON的各种生物降解途径,为研究生物学方法控制粮食与饲料中DON含量提供一定参考。As one of the most widely distributed Fusarium mycotoxin,deoxynivalenol（DON） not only results in the enormous loss of global food industry,but also lead to serious threat for food safety.The appropriate application of microbial degradation metabolism of DON in raw materials has become a hot topic.In this paper,biodegradation,transformation and absorption pathways including 3C—OH oxidation,de-epoxidation,hydration,glycosylation,3C-epimerization,binding and absorption and other mechanisms are summarized,which will provide the better understanding of biodegradation,transformation or absorption mechanisms of DON,and theoretical basis for the control of DON in food and feed through microbiological strategies.
