摘要: 脱氧雪腐镰刀菌烯醇(deoxynivalenol,DON)是目前粮食作物中由于霉变产生的分布最为广泛、影响较大的单端孢霉烯族化合物之一。DON在植物、微生物作用下会转化形成各种隐蔽型毒素,且这些生物转化往往并不彻底,使中毒症状更加复杂,从而增加了粮食及其副产品的风险。本文主要综述各类生物对DON的转化模式及其对所形成的隐蔽型毒素类型、分布及毒性作用的影响,以期为今后DON及其隐蔽型毒素的降解研究提供参考。

Abstract: Deoxynivalenol (DON) is one of the most widely distributed and most important trichothecenes in moldy grains. DON is metabolized by plants and microorganisms into various masked mycotoxins, and these transformations are usually incomplete, resulting in complex poisoning symptoms and thereby increasing the safety risk of cereal crops and their by-products. This paper mainly reviews the transformation patterns of DON by various organisms and their effects on the type, distribution and toxicity of its masked forms, which is expect to provide reference for future research on the degradation of DON and its masked forms.

Key words: deoxynivalenol; plant transformation; microbial degradation; metabolism; masked mycotoxins
