磺胺甲基异恶唑的好氧生物降解研究现状

磺胺甲基异恶唑是广泛应用的抗生素,属于药品及个人护理品（Pharmaceutical and Personal Care Products,PPCPs）污染物的典型代表物质.近年来,该物质在环境中的检出率逐渐增加,成为了一种新兴污染物,对人体及生态环境造成危害.磺胺甲基异恶唑具有难于生物降解的特性,然而目前在好氧条件下,利用生物方法处理该物质已初见成效,它将成为今后的研究热点.本文对磺胺甲基异恶唑的好氧生物降解研究现状进行了系统的综述,包括具有降解该物质能力的微生物类群、该物质好氧降解的影响因素及降解产物分析,在此基础上提出了磺胺甲基异恶唑好氧生物降解未来进一步研究的方面.

Advances in Aerobic Biodegradation of Sulfamethoxazole

Sulfamethoxazole（SMX）, a kind of widely used antibiotics, has become One of the representative substances of PPCPs. In recent years, the ubiquitous occurrence of SMX in the environment with the detected frequency is increasing. SMX is anew emerging pollutant, which has effect on human and environment. SMX is hard to be degraded by microorganism, however, in aerobic condition, biological treatment method has given initial results. It will be a hot area of research for SMX removal. This paper mainly reviews the advances in aerobic biodegradation of SMX, including family and group of microbes with degradation a- bility, the influential factors for biodegradation, and identification of SMX biodegradation products. And on this basis, the trends of the research are analyzed.
