The objective of this study was to examine diverse metal-reduction and biomineralization by metal-reducing bacteria (MRB) enriched from marine sediments of the Ulleung Basin, East Sea. Microbial diversity of the MRB was identified by 16S rRNA gene analysis. Microbial metal reduction was studied using diverse redox-sensitive metals [Mn(IV), Fe(III), Se(VI), Au(III)] as electron acceptors and various electron donors (acetate, formate, glucose, lactate, and pyruvate) at 8°C or 25°C. XRD and SEM/TEM-EDS were used to analyze mineralogical, chemical, and morphological characteristics of the minerals formed by bacteria. The MRB including Shewanella sp., Clostridium sp., Vibrio sp. and others, formed rhodochrosite (MnCO3), and magnetite (Fe3O4)/siderite (FeCO3) by Mn(IV) and Fe(III) reduction processes, respectively. They also reduced Se(VI) and Au(III) into Se(0) and Au(0), respectively. These results imply that the MRB are able to reduce various redox-sensitive metals and they may influence biomineralization and cycle of metals and organic matter in subsurface environments.
