细菌降解邻苯二甲酸酯的研究进展

Advances in biodegradation of phthalates esters

摘要:

邻苯二甲酸酯 (Phthalates esters, PAEs) 是一类混合在塑料中以增强其可塑性和多功能性的有机化合物。同时，PAEs也是一种典型环境内分泌干扰物，长期生产和使用塑料制品已对环境和生物体乃至人类身体健康造成危害。研究发现微生物降解已成为削减环境中PAEs的主要途径。文中对近年来国内外在PAEs的结构及分类、毒理学效应、在环境中的污染状况、细菌降解的菌株多样性、降解途径及分子机制等方面的相关研究进行了总结与回顾，以期对解决PAEs的污染问题提供参考。

Abstract:

Phthalates esters (PAEs) are important organic compounds used as plasticizers to enhance their plasticity and versatility. At the same time, PAEs are also typical environmental endocrine disruptors. Long-term production and use of plastic products have caused harm to the environment and organisms, as well as human health. Previous studies found that biodegradation has become a main pathway to reduce PAEs in the environment. This article reviews PAEs’ structural characteristics and classifications, toxicology, pollution in the environment, summarizes the diversity of PAEs-degrading bacterial species, and explores the possible mechanisms of bacterial PAEs degradation. The article may provide some reference in solving the problem of PAEs pollution.
