Dissimilatory metal-reducing bacteria (DMRB) are a class of bacteria that couple the oxidation of organic matter to the reduction of a metal species in the process of anaerobic respiration.〔Lovley, D. R. (1991). Dissimilatory Fe (III) and Mn (IV) reduction. Microbiological reviews, 55(2), 259.〕 Species that typically use ferric iron as an electron acceptor are also known as dissimilatory iron-reducing bacteria (DIRB). Some species of DMRB produce compounds that act as electron shuttles, enabling them to perform metal reduction from a distance. In natural systems, secondary minerals may form as a byproduct of bacterial metal reduction.〔Lovley, D. R., Stolz, J. F., Nord, G. L., & Phillips, E. J. (1987). Anaerobic production of magnetite by a dissimilatory iron-reducing microorganism. Nature, 330(6145), 252-254〕 Known species of DMRB include: * ''Shewanella spp.'' * ''Geothrix fermentans'' * ''Geobacter spp.'' ==References== 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dissimilatory metal-reducing bacteria」の詳細全文を読む スポンサード リンク
