呕吐毒素降解微生物的研究进展

Research Progress on Microbial Degradation of Deoxynivalenol

呕吐毒素在玉米、小麦和大麦等谷物和禽畜饲料中检出率很高,是污染最严重的霉菌毒素之一,严重危害食品安全。因此,如何高效安全地去除呕吐毒素成为研究的热点。相比传统的物理和化学处理方法,生物降解法因具有高效、对环境友好和特异性强等优势而广受关注。作者概述了生物降解呕吐毒素的方法,重点总结了降解菌株的种类、降解酶及其基因,并且阐述了其在实际应用中的局限和前景。

Deoxynivalenol has a high detectable rate in corn,wheat,barley and livestock feed.It is one of the most contaminated mycotoxin and harmful to food safety.Therefore,how to remove deoxynivalenol efficiently and safely has become a research hotspot.Compared with the traditional physical and chemical treatment methods,biodegradation has attracted much attention due to its high efficiency,environmental friendliness and high specificity.This paper summarizes the methods of biodegradation of deoxynivalenol,the species,enzymes and genes of biodegradation strains.The limitations and prospects in practical application are also discussed.
