The mineral-respiring bacterium Shewanella oneidensis uses a protein complex, MtrCAB,
composed of two decaheme cytochromes, MtrC and MtrA, brought together inside a …

A number of species of Gram-negative bacteria can use insoluble minerals of Fe (III) and Mn
(IV) as extracellular respiratory electron acceptors. In some species of Shewanella, deca …

Shewanella oneidensis MR-1 is purported to express outer membrane cytochromes (eg,
MtrC and OmcA) that transfer electrons directly to Fe (III) in a mineral during anaerobic …

The biochemical mechanisms by which microbes interact with extracellular soluble metal
ions and insoluble redox-active minerals have been the focus of intense research over the …

The purified outer membrane bacterial protein OmcA binds densely to the surface of
hematite (Fe2O3), permitting direct electron transfer to this solid mineral to reduce Fe (III) …

Many subsurface microorganisms couple their metabolism to the reduction or oxidation of
extracellular substrates. For example, anaerobic mineral-respiring bacteria can use external …

Dissimilatory microbial reduction of insoluble Fe (III) oxides is a geochemically and
ecologically important process which involves the transfer of cellular, respiratory electrons …

Some bacterial species are able to utilize extracellular mineral forms of iron and manganese
as respiratory electron acceptors. In Shewanella oneidensis this involves decaheme …

Using a series of multiheme cytochromes, the metal-reducing bacterium Shewanella
oneidensis MR-1 can perform extracellular electron transfer (EET) to respire redox-active …

Mechanisms by which dissimilatory iron-reducing bacteria utilize iron and manganese oxide
minerals as terminal electron acceptors for respiration are poorly understood. In the absence …
