摘要
黏土矿物作为土壤的关键组分,与微生物通过多种机制发生相互作用,包括酶催化驱动的矿物氧化还原反应,以及通过胞外聚合物(EPS)介导的矿物表面吸附等。本文探讨了矿物类型、微生物群落、作用时间以及pH、温度、水分和养分等土壤条件对微生物与黏土矿物相互作用的影响。在应用层面,微生物-矿物复合体系在重金属吸附、固定及有机污染物降解中有着关键作用。近年来,关于微生物与黏土矿物相互作用机制及其在生态修复中的应用研究已取得显著进展,但在污染物复合污染修复机制等方面仍需突破,以进一步推动绿色修复技术的发展。
Abstract
As a key component of soil, clay minerals interact with microorganisms through various mechanisms, including enzyme-catalyzed redox reactions of minerals and mineral surface adsorption medi- ated by extracellular polymeric substances (EPS). This paper examines the influence of factors such as mineral types, microbial species, interaction duration, and soil conditions ( e. g. , pH, temperature, moisture, and nutrients ) on the interactions between microorganisms and clay minerals. At the application level, microbe-mineral composite systems play a crucial role in heavy metal adsorption, im- mobilization, and organic pollutant degradation. This literature review indicates that significant advance- ments have been made in recent years regarding the understanding of microbial-clay mineral interactions and their applications in ecological remediation. However, critical challenges such as the remediation mechanisms for mixed contaminant systems remain to be addressed to further advance the development of green remediation technologies.
