Novel Mode of Microbial Energy Metabolism: Organic Carbon Oxidation Coupled to Dissimilatory Reduction of Iron or Manganese
TLDR
This is the first demonstration that microorganisms can completely oxidize organic compounds with Fe(III) or Mn(IV) as the sole electron acceptor and that oxidation of organic matter coupled to dissimilatory Fe( III), Mn( IV), or Mn (IV) reduction can yield energy for microbial growth. Expand
Dissimilatory Fe(III) and Mn(IV) reduction.
TLDR
The physiological characteristics of Geobacter species appear to explain why they have consistently been found to be the predominant Fe(III)- and Mn(IV)-reducing microorganisms in a variety of sedimentary environments. Expand
Electricity Production by Geobacter sulfurreducens Attached to Electrodes
TLDR
The results suggest that the effectiveness of microbial fuel cells can be increased with organisms such as G. sulfurreducens that can attach to electrodes and remain viable for long periods of time while completely oxidizing organic substrates with quantitative transfer of electrons to an electrode. Expand
Humic substances as electron acceptors for microbial respiration
HUMIC substances are heterogeneous high-molecular-weight organic materials which are ubiquitous in terrestrial and aquatic environments. They are resistant to microbial degradation1 and thus are not… Expand
Organic Matter Mineralization with Reduction of Ferric Iron in Anaerobic Sediments
TLDR
Results indicate that iron reduction can outcompete methanogenic food chains for sediment organic matter when amorphous ferric oxyhydroxides are available in anaerobic sediments, and the transfer of electrons from organic matter to ferric iron can be a major pathway for organic matter decomposition. Expand
Rapid Assay for Microbially Reducible Ferric Iron in Aquatic Sediments
TLDR
A newly developed chemical assay for microbially reducible iron based on the reduction of poorly crystalline ferric iron by hydroxylamine under acidic conditions provides a correction for the high concentrations of solid ferrous iron which may also be extracted from sediments with acid. Expand
Electrode-Reducing Microorganisms That Harvest Energy from Marine Sediments
TLDR
A specific enrichment of microorganisms of the family Geobacteraceae is reported on energy-harvesting anodes, and it is shown that these microorganisms can conserve energy to support their growth by oxidizing organic compounds with an electrode serving as the sole electron acceptor. Expand
Microbial reduction of uranium
REDUCTION of the soluble, oxidized form of uranium, U(VI), to insoluble U(IV) is an important mechanism for the immobilization of uranium in aquatic sediments and for the formation of some uranium… Expand
Extracellular electron transfer via microbial nanowires
TLDR
Results indicate that the pili of G. sulfurreducens might serve as biological nanowires, transferring electrons from the cell surface to the surface of Fe(iii) oxides, indicating possibilities for other unique cell-surface and cell–cell interactions, and for bioengineering of novel conductive materials. Expand
Electricity generation by direct oxidation of glucose in mediatorless microbial fuel cells
TLDR
A novel microorganism is reported on, Rhodoferax ferrireducens, that can oxidize glucose to CO2 and quantitatively transfer electrons to graphite electrodes without the need for an electron-shuttling mediator, which results in stable, long-term power production. Expand
