Abstract:

Endosulfan, a chlorinated pesticide of the cyclodiene group, is used extensively for the protection of cotton, tea and sugarcane crops. Endosulfan residue has led to the contamination of soil and water environments. It is also a serious threat to human and animal health. The toxicity, application situation and residue of endosulfan were introduced briefly. The residue causes were analyzed too. The degradation of pesticides in soil by microorganism was an effective method. The types of microorganism which degraded endosulfan, the mechanism of degradation were summarized in this paper. To realize a practical application of endosulfan-degrading microorganisms on fields, isolation of highly efficient degrading microorganisms, construction of genetically engineered microorganisms, environmental microbial ecosystem of degrading microorganisms should be enhanced.
