摘要
白僵菌素(beauvericin,BEA)和恩镰孢菌素(enniatins,ENNs)是由镰刀菌属的多种真菌产生的六酯肽类真菌毒素,该类毒素对上皮细胞、免疫细胞、卵巢细胞等具有很强的毒性作用。本文主要针对能产生BEA和ENNs的重要产毒镰刀菌的形态学特征、分子遗传学特征以及影响BEA和ENNs产生的环境条件如温度、底物等因素进行概述。重点阐述了产毒镰刀菌在两类毒素合成酶的基因水平和氨基酸水平的差异及影响产毒等主要因素,为BEA和ENNs及其产毒镰刀菌的预防和控制提供理论依据。
Beauvericin(BEA) and enniatins(ENNs) are a group of hexadepsipeptides mycotoxins produced by several species of Fusarium, which show strong toxic effects on epithelial cells, immune cells and ovarian cells. The morphology and the molecular genetic characteristics of toxin-producing Fusarium species are introduced, as well as the environmental conditions, such as temperature and substrate, which can influence BEA and ENNs production. The differences in genetic level and the amino acid level about synthetase of two types of mycotoxins, and their influencing factors about mycotoxin-producing Fusarium species are expounded emphatically. It will provide a theoretical basis for the prevention and control of two types of mycotoxin and mycotoxin-producing Fusarium species.
