摘　　要：玉米赤霉烯酮是由镰刀菌属真菌产生的一种真菌毒素,也是粮食及其加工制品中最常见的真菌毒素之一,严重威胁着人类的健康和动物的生产性能。真菌毒素的脱毒方法主要有物理、化学和生物法,目前由于物理和化学脱毒方法存在着脱毒效果不彻底、成本高、营养成分损失、化学试剂残留等缺点,限制了其应用。生物法具有反应条件温和、专一性好、去毒性效率高、无化学试剂残留、不破坏营养等优点,是一种理想的脱毒方法。对近年来国内外玉米赤霉烯酮的生物脱毒研究进行了概述,并对已发现具有降解玉米赤霉烯酮能力的菌株、脱毒方式及脱毒产物的毒性等研究内容作了重点介绍,旨在为玉米赤霉烯酮的生物脱毒研究提供参考。Zearalenone(ZEN)is a secondary meatabolite mainly produced by Fusarium species,and one of the most common mycotoxins of grains.Its subsequent products pose considerable risk to humans and animals.Most of physical or chemical approaches are not widely available due to disadvantages of destruction of nutrients,incomplete detoxification,chemical residues and expensive cost involved in detoxification process.Microbiological detoxification would be the ideal way by which toxin was catalyzed into relatively less or even no toxic substances by microbial enzymes.Recent advances in biological detoxification of ZEN were summarized,including the species of microorganisms,enzymes,pathways and products involved in biological detoxification process,with an aim to provide a theoretical reference for further research on biological detoxification of ZEN.
