摘　　要：微生物燃料电池(Microbial fuel cell,MFC)是未来理想的发电装置,而铁还原菌是目前MFC研究中重要的产电微生物.自然界中并无微生物产电的直接进化压力,而MFC电极与自然界中Fe(III)氧化物同为难溶性胞外电子受体,研究表明,铁还原菌对二者的还原有相似机制.基于铁还原菌的MFC具有无需外加介体,可利用多种有机电子供体作为燃料,能量转化率高等优点.本文分析了铁还原菌还原电极和还原Fe(III)氧化物机制的相似性,对近年来基于各种铁还原菌的MFC研究进展进行分述和总结,提出了铁还原菌MFC的发展趋势和研究方向.Fe （Ⅲ）-reducing bacteria （FRB） are important electrogenic microorganisms in microbial fuel cells （MFCs）. There has been no known evolutionary pressure on the microorganisms to produce electricity. Therefore, it is assumed that the ability of electrogenic microorganisms to produce electricity is related to their capacity to transfer electrons onto natural extracel- lular electron acceptors, such as Fe（Ⅲ） oxides. An electrode of MFC and Fe（Ⅲ）-oxide in nature are both the extracellular insoluble electron acceptors for FRB. The similar metabolisms between electron transfer to an electrode and reducing insoluble Fe（Ⅲ）-oxide by FRB have been analyzed. This article summarizes the information on the recent development of FRB-based MFCs, and points out that the MFCs based on FRB have a good prospect, because of their high efficiency of energy conversion and needlessness of exotic mediator.
