伏马毒素削减方法研究进展

摘要

Fumonisin (FB)is a kind of water soluble secondary metabolites produced from genus fusari-um under a certain temperature and humidity condition.It not only greatly pollutes grain crops which will cause reduction of output but cause huge damage to humans and animals.Recently,degradation of FB has become a research hotspot.Although the traditional physical and chemical methods can reduce part of fumonisins the degradation is not complete,the nutritional components are damaged and some uncertainty is introduced,while the reactions by biological methods are mild,high efficiency and friendly to environ-ment.Now,the research on degradation of FB has reached molecular levels.Correlative degrading bacte-ria have been filtrated and some degrading genes have been cloned.The research progress in degradation of FB was summarized.The advice for degradation of FB was proposed.%伏马毒素（Fumonisins，FB）是镰刀菌属（Fusarium spp．）在一定温度和湿度条件下产生的水溶性次级代谢产物。它不仅污染粮食作物造成粮食减产，还对人畜的健康造成巨大损害，近年来关于 FB 削减已成为研究热点。传统的物理、化学方法虽能一定程度削减 FB，但削减不彻底，破坏营养成分，引入不确定因素，而生物方法反应温和，效率高，环境友好。目前，国际上对 FB 的削减研究已进入分子水平，已筛选到相关的降解菌，降解基因也已被克隆。综述了 FB 削减方法的研究进展，提出 FB 削减的有关建议。
