玉米赤霉烯酮是一种有毒的真菌次生代谢产物,是世界上污染粮食范围最广泛的真菌毒素之一,它不仅具有生殖毒性,还具有细胞毒性、免疫毒性以及致癌作用。传统控制玉米赤霉烯酮的方法主要有物理法和化学法,但上述两种方法都具有局限性,近年来,采用拮抗酵母菌控制谷物中玉米赤霉烯酮展现出良好的应用前景。本文对拮抗酵母菌控制玉米赤霉烯酮的机制研究进行了综述,包括酵母菌细胞壁对玉米赤霉烯酮的吸附作用,酵母菌对玉米赤霉烯酮的降解作用,进一步探讨了相关作用对粮食污染生防效果的影响。
Zearalenone is a toxic fungal secondary metabolite, and is one of the mycotoxins that can contaminate foods widely. It not only has reproductive toxicity, but also has cytotoxicity, immune toxicity and carcinogenic effects. Even though physical and chemical treatments are commonly used to control zearalenone, their application is limited because of their disadvantages. Controlling zearalenone in cereals with antagonistic yeasts has represented a promising future. In this article, we present the progress in controlling zearalenone with antagonistic yeast, including the effect of yeast cell wall adsorption on zearalenone and the mechanisms of zearalenone degradation by antagonistic yeasts, and discuss the interaction and its effect on the biocontrol activity against food pollution.
