| 摘 要： | 在氧化乐果和葡萄糖共基质条件下,曲霉G21优先利用葡萄糖作为碳源,葡萄糖耗尽后开始快速降解氧化乐果,高浓度氧化乐果抑制了曲霉G21的生物降解活性.GC-MS分析表明,曲霉G21降解氧化乐果的主要中间产物为O,O,S-三甲基磷酸酯,氧化乐果降解率提高不会导致该有毒中间产物的累积效应.

| Abstract: | The characteristics and intermediate product of the degradation of omethoate by Aspegillus were studied. Under the condition of glucose and omethoate as co-substrate, Aspergillus G21 first utilized glucose as carbon source, and after glucose was used up, it degraded and utilized omethate rapidly. High concentration of omethoate inhabited its biodegradation ability. GC/MS analysis showed that O,O,S-trimethyl phosphorothioate (TEP) was the main intermediate product in the degradation of omethoate by Aspegillus, and improving the degradation rate of omethoate would not lead to the accumulation effect of the toxic intermediate product. |
