摘要

在土壤和水环境中存在大量微生物，附着在其表面的胞外聚合物（extracellular polymeric substances，EPS）在重金属及有机污染物等的迁移和转化中发挥着重要作用。以保护水土环境、提升污染水土修复效率的科学和工程问题为目标，针对近年来国内外对EPS的组成和结构、影响微生物EPS分泌的因素、EPS的提取方法以及其生物降解性等方面的研究成果进行了综合评述，系统分析了EPS参与土壤和水环境中金属及有毒有机物质生物降解和去除的微观机制，进而针对现有研究中存在的问题，对EPS在土壤和水环境中的进一步研究空间，特别是如何提高理解EPS的生物和化学修复工程意义提出展望。

Abstract

There are a large number of microorganisms in the soil and water environment. The extracellular polymeric substances (EPS) attached on their surfaces play an important role in the migration and transformation of heavy metals and organic contaminants. This paper aims at protecting the water and soil environment

improving the level of problem-solving of science and engineering in remediation efficiency of contaminated water and soil. Various studies conducted so far about composition and structure of EPS

factors affecting the EPS secretion of microorganism

the EPS extraction methods and biodegradability of EPS were reviewed. The microscopic mechanism of EPS in biodegradation and removal of metals and toxic organic substances in soil and water environment was systematically analyzed. The further perspectives of EPS research in soil and water environment are proposed in considering the current problems and issues in the related studies

and particularly in supporting bio-chemical remediation engineering of contaminants using the EPS scientific understanding.
