Abstract:
In this paper, a high performance liquid chromatography method was established for determination of the degradation rates of chlorimuron-ethyl.The biodegradation of herbicide chlorimuron-ethyl in the soil by different strains was researched systematically.The results showed that the degradation rates of herbicide chlorimuron-ethyl by Aspergillus niger, Penicillium, F8 and F31 were significantly different in the soil.The herbicide chlorimuron-ethyl could bedegraded effectively by all these four strains.The degradation ability was Aspergillus niger＞F31＞ Penicillium＞F8.The degradation rates of herbicide chlorimuron-ethyl by Aspergillus niger respectively mixed with Penicillium, F8 amd F31 were significantly different With the increase of proportion of Aspergillus niger, herbicide degradation ability was significantly enhanced. The F31 and Aspergillus nige blend was the best combination and the degradation rate reached 86.43%. On the basis of binary mixture, addition of a small amount of Penicillium could further improve the ability of degradation.
