环境雌激素的微生物代谢

The microbial degradation of environmental estrogens

摘要:

环境雌激素作为一类重要的新型环境污染物，可通过干扰生物体的内分泌系统危害生物体健康。微生物降解是去除环境雌激素与进行环境修复的主要手段。本文归纳整理了目前研究较深入的雌激素降解微生物，类比阐述了其预测的降解通路与降解机制，并对后续环境雌激素降解研究的主要内容与方向进行了展望。

Abstract:

Environmental estrogens, the major components in the new kinds of environment pollutants, threaten the health of human and animals by its effect on the functions of endocrine system. Microbial degradation is considered as the efficient method in the removal of estrogenic chemicals and the remediation of polluted environment. This paper discusses the well-studied estrogen-degrading microorganisms, compares their degradation products and pathways, then summarizes the proposed microbial degradation mechanisms of estrogens, and finally forecasts the potential research interests in the biodegradation of environmental estrogen.
