摘　　要：磺酰胺类抗生素由于其增强病原细菌的抗性并促进抗生素抗性传播的能力而引起越来越多的关注。在自然和工程生态系统中,生物降解在磺酰胺消散中都起着重要作用。本文概述了不同系统中磺酰胺生物降解,并总结了相关的磺酰胺降解物种和代谢途径。且从原位降解物以及磺酰胺生物降解的代谢途径和功能基因从微生物降解的角度出发展开综述研究,总结出目前降解SAs最有效的方法。Sulfonamides have attracted more and more attention because of their ability to enhance the resistance of pathogenic bacteria and promote the spread of antibiotic resistance.Biodegradation plays an important role in the dissipation of sulfonamide in both natural and engineered ecosystems.The biodegradation of sulfonamide in different systems was summarized,and the related sulfonamide degradation species and metabolic pathways were summarized.In addition,the metabolic pathways and functional genes of in situ degradation and sulfonamide biodegradation were reviewed from the perspective of microbial degradation,and the most effective degradation methods of SAs were summarized.
