中文摘要：本研究将一株梨孢镰刀菌在不同浓度的硒合成培养基中培养，旨在研究硒对该菌株产生T-2毒素的影响。结果发现，T-2毒素在发酵产品中的产量受培养基中硒的影响，且20 mg/L的硒浓度抑制发酵产品中梨孢镰刀菌产生T-2毒素的效果最好。
外文摘要：The objective of this study was to investigate the effects of selenium on the production of T-2 toxin by a Fusarium poae strain cultured in a synthetic medium containing different concentrations of selenium. The T-2 toxin contents in fermentative products were evaluated by a high performance liquid chromatography (HPLC). The results showed that the production of T-2 toxin was correlated with the concentration of selenium added to the medium. In all three treatments, the addition of 1 mg/L selenium to the medium resulted in a lower toxin yield than the control (0 mg/L); the yield of the toxin began to increase when selenium concentration was 10 mg/L, while it decreased again at 20 mg/L. In summary, T-2 toxin yield in the fermentative product was affected by the addition of selenium to the medium, and a selenium concentration of 20 mg/L produced the maximum inhibitory effect of T-2 toxin yield in the fermentative product of F. poae.
