微生物降解磺酰脲类除草剂的研究进展

Research Progress on Bioremediation of Sulfonylurea Herbicides

磺酰脲类除草剂具有高效和高选择性等优点,但其微量残留在土壤环境中就会对敏感作物会产生药害。因此,解决其残留问题便成为当今的研究热点。其中微生物降解是磺酰脲类除草剂降解的最有效方法之一。本文综述了降解磺酰脲类除草剂微生物种类、降解机理及研究现状,并展望了微生物降解磺酰脲类除草剂修复污染土壤的前景。

Sulfonylurea herbicides were of residue in the soil environment would lem was crucial. Microbial degradation highly efficiency and strong selective, but a small amount injury sensitive crops. So how to solve the residual prob- was one of effective methods for the degradation of Sul- fonylurea Herbicides. This paper reviewed the types of microbial degradation, mechanism and the status of sulfonylurea herbicides, and finally prospect microbial of sulfonylurea herbicides on remediation of contaminated soil. degradation degradation
