| Abstract: | Objective ] The aim was to screen one efficient imazethapyr-degrading bacterium. Method ] Some imazethapyr-degrading bacterium strains which were collected from Harbin suburb of Heilongjiang were isolated, screened and identified. Result] Three degradation strains were selected, containing CX-white, CX-red and CX-yellow. The degradation rates of CX-white, CX-red and CX-yellow were 58.98%, 38.82% and 13.19%, respectively. Using the DNA-Extracted kit, the DNA of CX-white were extracted and amplified by PCR. The CX- white which could degrade imazethapyr efficiently belonged to Bacillus sp. Conclusion] The research results lay theoretical basis for field application and industrial production of imazethapyr-degrading bacterium. |
