Abstract

Many studies have used microbial fuel cell (MFC) to enhance biological reactions to improve the removal of pollutants, but the mechanisms of enhancement are unclear. The fundamental difference between biological reactions in MFC and traditional biological reactions lies in the presence of the electric field. This review analyzes the current research status of the mechanism of electron transfer by electro-active bacteria (EABs) in MFC system and the modulation effect of electric field on microorganisms, and summarizes the research progress on the enhancement mechanisms of nitrogen removal by MFC with a focus on biocathode denitrification. In addition, constructive suggestions on how to further clarifying the enhancement mechanism of MFC on biological responses have been also put forward. This review provides the theoretical basis for further investigation of the mechanisms of enhancement of other biological reactions by MFC.

微生物燃料电池对生物反应的电场效应：综述

许多研究利用微生物燃料电池（MFC）来增强生物反应，以提高污染物的去除率，但增强机制尚不清楚。MFC 中的生物反应与传统生物反应的根本区别在于电场的存在。本综述分析了电活性细菌（EABs）在 MFC 系统中的电子传递机理和电场对微生物的调控作用的研究现状，总结了 MFC 脱氮强化机理的研究进展，重点介绍了生物阴极脱氮。此外，还就如何进一步阐明 MFC 对生物反应的增强机制提出了建设性建议。本综述为进一步研究 MFC 对其他生物反应的增强机制提供了理论依据。
