Isolation, screening and identification of synthetic pyrethroid insecticides-degrading strains |
| |
| Abstract: | 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. |
