Redox mediators (RM) are natural or artificial compounds used by microorganisms as electron acceptors and electron donors during electron transfer. Evidence collected in the last years indicates that the application of RM in bioelectrochemical systems (BES) enhanced the electron transfer from microorganisms to anodes and from cathodes to microorganisms. This review summarizes the results of using soluble or immobilized RM in BES to produce electricity and for the treatment of contaminants from wastewater effluents. In addition, future research focused on biohydrogen production, recovery or removal metals, and the use of humic substances (HS) extracted from natural environment is proposed.
氧化还原介质（RM）是微生物在电子转移过程中用作电子受体和电子供体的天然或人工化合物。近年来收集的证据表明，在生物电化学系统（BES）中应用 RM 可增强微生物向阳极和阴极向微生物的电子转移。本综述总结了在 BES 中使用可溶性或固定化 RM 来发电以及处理废水流出物中的污染物的结果。此外，还提出了未来专注于生物制氢、回收或去除金属以及利用从自然环境中提取的腐殖物质（HS）的研究。
