The Geobacteraceae group of bacteria possesses a natural ability to link cytoplasmic
metabolism with redox chemistry at their external surface. Although this capability likely …

Reaching a depth of 713 m below the surface, the Soudan Underground Iron Mine (Soudan,
MN, USA) transects a massive Archaean (2.7 Ga) banded iron formation, providing a …

Abstract Multiple Fe (III)-reducing Geobacter species including the model Geobacter
sulfurreducens are thought to be incapable of carbon dioxide fixation. The discovery of the …

Geobacter sulfurreducens is capable of anaerobic respiration with Fe (III) as a terminal
electron acceptor via a membrane-bound Fe (III) reductase activity associated with a large …

A 9.6 kDa periplasmic c-type cytochrome, designated PpcA, was purified from the Fe (III)-
reducing bacterium Geobacter sulfurreducens and characterized. The purified protein is …

To investigate electron transport in the dissimilatory iron-reducing isolate Geobacter
metallireducens strain GS-15, assays for redox enzymes and characterizations of …

Geobacteracea are distinct for their ability to reduce insoluble oxidants including minerals
and electrodes without apparent reliance on soluble extracellular electron transfer (ET) …

Direct interspecies electron transfer (DIET) may be most important in methanogenic
environments, but mechanistic studies of DIET to date have primarily focused on cocultures …

Nanoscale magnetite can facilitate microbial extracellular electron transfer that plays an
important role in biogeochemical cycles, bioremediation and several bioenergy strategies …

Geobacter species specialize in making electrical contacts with extracellular electron
acceptors and other organisms. This permits Geobacter species to fill important niches in a …
