Many iron (Fe) redox processes that were previously assumed to be purely abiotic, such as
photochemical Fe reactions, are now known to also be microbially mediated. Owing to this …

The multi‐heme, outer membrane c‐type cytochrome (c‐C yt) OmcB of G eobacter
sulfurreducens was previously proposed to mediate electron transfer across the outer …

The naturally widespread process of electron transfer from metal reducing bacteria to
extracellular solid metal oxides entails unique biomolecular machinery optimized for long …

Microbe-mineral interactions occur in diverse modern environments, from the deep sea and
subsurface rocks to soils and surface aquatic environments. They may have played a central …

The biochemical and molecular mechanisms used by alkaliphilic bacterial communities to
reduce metals in the environment are currently unknown. We demonstrate that an …

The porin-cytochrome (Pcc) protein complex is responsible for trans-outer membrane
electron transfer during extracellular reduction of Fe (III) by the dissimilatory metal-reducing …

Iron oxyhydroxides (FeOOH) are common crystalline forms of iron that play a critical role in
technology and the natural environment via a variety of important reduction-oxidation …

Bioelectrochemical systems (BESs) share the principle of the microbially catalyzed anodic
substrate oxidation. Creating an electrode interface to promote extracellular electron transfer …

The ability of dissimilatory metal-reducing microorganisms (DMRM) to conduct extracellular
electron transfer with conductive cellular components grants them great potential for …

Microorganisms overcome the considerable hurdle of respiring extracellular solid substrates
by deploying large multiheme cytochrome complexes that form 20 nanometer conduits to …
