摘　　要：分离出1株能以拟除虫菊酯类杀虫剂为唯一碳源和能源的降解菌w10j15,经鉴定为阴沟肠杆菌(Enterobactercloa-cap).在30℃、pH7.0基础培养基发酵液中,该菌对100mg·L-1的联苯菊酯、甲氰菊酯和氯氰菊酯的降解率分别为52.43%、50.76%和56.89%,对有机磷农药也有一定的降解力,对甲胺磷、敌敌畏和毒死蜱的降解率分别为21.00%、11.99%和12.05%.A bacterial strain named as w10j15, which could use synthetic pyrethroid insecticides as sole carbon and energy sources, was isolated, and has been identified as Enterobacter cloacap. At the condition of 30 ℃, pH7.0, the removal rates of bifenthrin, fenpropathrin and cypermethrin with the content of 100 mg·L-1 were 52.43%, 50.76% and 56.89%, respectively. The strain could also degradate organophosphorus pesticides, the degradation rates of methamidophos, dichlorvos and chlorpyrifos were 21.00%, 11.99% and 12.05%, respectively.
