摘要:

脱氧雪腐镰刀菌烯醇是镰刀菌产生的次级代谢产物,广泛存在于受污染的农作物和饲料中,不仅给农业经济造成重大损失,也给人类和动物健康带来潜在威胁。传统控制脱氧雪腐镰刀菌烯醇的方法主要有物理法和化学法,但上述两种方法都具有局限性。近年来,利用微生物生物转化方法进行脱毒展现出良好的应用前景。本文概述了脱氧雪腐镰刀菌烯醇的化学性质、毒性作用以及生物脱毒方面的研究进展,为研究生物学方法控制粮食与饲料中脱氧雪腐镰刀菌烯醇含量提供参考。

Abstract:

Deoxynivalenol (DON), a secondary metabolite produced by Fusarium, is widely found in polluted grains
and animal feeds, which can cause severe losses to the global agricultural economy as well as potential threats to human
and animal health. The physical and chemical treatments mainly used to control DON are limited by their disadvantages.
Recently, the microbial biotransformation method has shown a promising future in DON control in cereals. This paper
outlines the basic chemical properties and toxicity of DON and recent progress in developing biological detoxification
methods, with the aim of providing theoretical basis for the microbial control of DON in foods and feeds.

Key words: deoxynivalenol, toxicity, adsorption, biodegradation, degradation mechanism
