摘　　要： 玉米赤霉烯酮是一种由镰刀菌产生的具有雌激素作用的真菌毒素,是世界上污染范围最广的一种镰刀菌素。由于物理、化学脱毒法存在较大弊端,生物去毒方法因其特异性、高效性及环境友好而日益被科学界所关注。目前玉米赤霉烯酮生物降解主要是微生物降解作用,本文紧跟国内外玉米赤霉烯酮的生物降解情况,文章介绍了降解菌株的种类,降解能力和最佳降解条件,包括降解产物毒性,降解酶基因的发掘,以及降解菌株和酶的应用方向及前景。 Zearalenone is an estrogenic mycotoxin produced by several fusarium species that occurs to pollution on a worldwide basis in cereal grains and animal feeds. Zearalenone degradation strategies include： physical, chemical and biological method. More and more concerns are being focused on the development of biotechnological strategies for zearalenone detoxification because physical and chemical strategies serious of disadvantagesfor mycotoxins detoxification, while biological method has advantages of specificity, efficient and environmental soundness. Now biodegradation is mainly used on microbiological deterioration. In this paper, we closely keep up with the domestic and overseas zearalenone biodegradation ; describes the kind of degrading bacteria, degradability and optimum degradation conditions; introduce the toxicity of degradation product, degradation enzyme gene excavation, as well as the direction of application of strain and enzyme and their prospects.
