脱氧雪腐镰刀菌烯醇生物脱毒的研究进展

脱氧雪腐镰刀茵烯醇作为谷物及其制品中最常见的真菌毒素之一,严重威胁着人类和动物的健康。由于物理、化学脱毒方法存在着营养成分流失、脱毒不彻底等问题,而不能被广泛应用。微生物通过酶促反应将毒素转化成低毒或者无毒物质的生物脱毒方法不仅避免了这些缺点,还具有条件温和、安全环保的优点,是一种理想的脱毒方法。对近年来国内外脱氧雪腐镰刀茵烯醇的生物脱毒研究进展进行了概述,并对脱毒菌株、脱毒酶、脱毒方式及脱毒产物等研究内容作了重点介绍,旨在为脱氧雪腐镰刀菌烯醇的生物脱毒研究提供参考。

Research Advancement on Biological Detoxification of Deoxynivalenol

Deoxynivalenol (DON) is one of the most common mycotoxins of grains and their subsequent products, posing considerable health risk to humans and animals. Though many physical or chemical approaches are available for mycotoxins detoxification, most of them are not widely available due to some drawbacks of destruction of nutrients and incomplete detoxification involved in detoxification process. Microbiological detoxification is the way by which toxin was catalyzed into less or no toxic substances by bacterial enzymes of microorganisms. Microbiological detoxification is considered as a desired detoxification strategy, because it not only overcomes the above shortcomings, but also has the advantages of mild reaction condition, safety and environmental friendliness. In this paper, it describes the summarization of DON biological detoxification research progress at home and abroad, especially the contents of species of microorganisms, enzymes, pathways and products involved in DON biological detoxification process, with an aim to provide a theoretical reference for the study of DON biological detoxification.
