The complete genome sequence of Geobacter sulfurreducens, a δ-proteobacterium, reveals unsuspected capabilities, including evidence of aerobic metabolism, one-carbon and complex carbon metabolism, motility, and chemotactic behavior. These characteristics, coupled with the possession of many two-component sensors and many c-type cytochromes, reveal an ability to create alternative, redundant, electron transport networks and offer insights into the process of metal ion reduction in subsurface… Expand
Geobacter sulfurreducens Can Grow with Oxygen as a Terminal Electron Acceptor
ABSTRACT Geobacter sulfurreducens, previously classified as a strict anaerobe, tolerated exposure to atmospheric oxygen for at least 24 h and grew with oxygen as the sole electron acceptor atExpand
The anoxic ferric microbial community contains abundant numbers of Geobacteraceae and Rhodoferrix species , dissimilatory iron-reducing bacteria capable of extracellular electron transfers
We have created a dynamic genome-scale metabolic model of Geobacter sulfurreducens and Rhodoferax ferrireducens, the two primary iron-reducers in uranium-contaminated grounds, in order to understandExpand
Diversity of promoter elements in a Geobacter sulfurreducens mutant adapted to disruption in electron transfer
TLDR
DNA sequences of upstream regions of coregulated operons in the adapted mutant are divergent, suggesting the presence of recognition sites for different transcriptional regulators and indicating that adaptation of the omcB mutant to growth on soluble Fe(III) has shifted the relevant expression networks involved to a more diverse molecular basis.

The genome of Desulfotalea psychrophila, a sulfate-reducing bacterium from permanently cold Arctic sediments.
TLDR
The genome sequence of D. psychrophila strain LSv54 is described, which consists of a 3 523 383 bp circular chromosome with 3118 predicted genes and two plasmids of 121 586 bp and 14 663 bp, which encodes more than 30 two-component regulatory systems. Expand
The electrifying physiology of Geobacter bacteria, 30 years on.
TLDR
A historical account of the environmental research that has set the foundation for numerous physiological studies and the laboratory tools that had provided novel insights into the role of Geobacter in the functioning of microbial communities from pristine and contaminated environments is provided. Expand
The RpoS sigma factor in the dissimilatory Fe(III)-reducing bacterium Geobacter sulfurreducens.
TLDR
This study suggests that RpoS plays a role in regulating metabolism of Geobacter under suboptimal conditions in subsurface environments. Expand
The hidden chemolithoautotrophic metabolism of Geobacter sulfurreducens uncovered by adaptation to formate
TLDR
Results demonstrate that G. sulfurreducens after adaptation reduced CO2 via the roTCA cycle can be harnessed for biotechnological applications and suggests hidden ecological functions for Geobacter. Expand
Studies of multi-heme cytochromes from Geobacter sulfurreducens
TLDR
The Geobacteraceae family predominates in the reduction of uranium in subsurface environments; its genome contains a large number of cytochromes c that function in metal reduction pathways, and the complete genome sequence of this organism has been determined. Expand
Characterization of Metabolism in the Fe(III)-Reducing Organism Geobacter sulfurreducens by Constraint-Based Modeling
TLDR
The results demonstrate that iterative modeling coupled with experimentation can accelerate the understanding of the physiology of poorly studied but environmentally relevant organisms and may help optimize their practical applications. Expand
The Geoglobus acetivorans Genome: Fe(III) Reduction, Acetate Utilization, Autotrophic Growth, and Degradation of Aromatic Compounds in a Hyperthermophilic Archaeon
TLDR
Genome analysis revealed pathways enabling oxidation of molecular hydrogen, proteinaceous substrates, fatty acids, aromatic compounds, n-alkanes, and organic acids through anaerobic respiration linked to Fe(III) reduction, suggesting that Geoglobus species could play an important role in microbial communities of deep-sea hydrothermal vents as lithoautotrophic producers.

Genome sequence of the dissimilatory metal ion–reducing bacterium Shewanella oneidensis
TLDR
This genome sequence represents a critical step in the elucidation of the pathways for reduction (and bioremediation) of pollutants such as uranium (U) and chromium (Cr), and offers a starting point for defining this organism's complex electron transport systems and metal ion–reducing capabilities.

Geobacter sulfurreducens sp. nov., a hydrogen- and acetate-oxidizing dissimilatory metal-reducing microorganism
TLDR
The ability to utilize either hydrogen or acetate as the sole electron donor for Fe(III) reduction makes strain PCA a unique addition to the relatively small group of respiratory metal-reducing microorganisms available in pure culture. Expand
The ‘strict’ anaerobe Desulfovibrio gigas contains a membrane‐bound oxygen‐reducing respiratory chain
TLDR
This report shows that membranes from Desulfovibrio gigas grown in fumarate/sulfate contain a respiratory chain fully competent to reduce dioxygen to water, showing that the relationships between oxygen and anaerobes are much more complex than originally thought. Expand

Enrichment of Members of the Family Geobacteraceae Associated with Stimulation of Dissimilatory Metal Reduction in Uranium-Contaminated Aquifer Sediments
TLDR
Stimulating microbial reduction of soluble U(VI) to insoluble U(IV) shows promise as a strategy for immobilizing uranium in uranium-contaminated subsurface environments and suggests that Geobacteraceae will be responsible for much of the Fe(III) and U( VI) reduction during uranium bioremediation in these sediments.

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
