Engineering Geobacter pili to produce metal:organic filaments

Biosensors and Bioelectronics, 2023
The organized self-assembly of conductive biological structures holds promise for creating new bioelectronic devices. In particular, Geobacter sulfurreducens type IVa pili have proven to be a versatile material for fabricating protein nanowire-based devices.

Influence of Anode Potentials on Current Generation and Extracellular Electron Transfer Paths of Geobacter Species

International Journal of Molecular Sciences, 2017
Geobacter species are capable of utilizing solid-state compounds, including anodic electrodes, as electron acceptors of respiration via extracellular electron transfer (EET) and have attracted considerable attention for their crucial role as biocatalysts

Desiccation Response of Geobacter sulfurreducens

ASME 2007 Summer Bioengineering Conference, 2007
Geobacter sulfurreducens is an electricity producing bacteria. It is used in bacterial fuel cells, microbial-based sensors, and catalytic surfaces for bioremediation. Further development of such applications requires stabilization and preservation of the bacteria as thin films on surfaces.

Proteins involved in electron transfer to Fe(III) and Mn(IV) oxides by Geobacter sulfurreducens and Geobacter uraniireducens

Microbiology, 2013
Whole-genome microarray analysis of Geobacter sulfurreducens grown on insoluble Fe(III) oxide or Mn(IV) oxide versus soluble Fe(III) citrate revealed significantly different expression patterns. The most upregulated genes, omcS and omcT, encode cell-surface c-type cytochromes, OmcS being required for Fe(III) and Mn(IV) oxide reduction.

Comprehensive genomic revision of the genus Geobacter, with the reclassification of Geobacter soli (Zhou et al. 2014) as a later heterotypic synonym of Geobacter anodireducens (Sun et al. 2014)

International Journal of Systematic and Evolutionary Microbiology
The taxonomy of Geobacter species has traditionally relied on 16S rRNA gene phylogenies, which often lack the resolution needed to distinguish closely related taxa. In this study, we employed an integrative phylogenomic approach combining 16S rRNA gene analysis, core genome phylogeny and ...

On Electron Transport through Geobacter Biofilms

ChemSusChem, 2012
AbstractGeobacter spp. can form a biofilm that is more than 20 μm thick on an anode surface by utilizing the anode as a terminal respiratory electron acceptor. Just how microbes transport electrons through a thick biofilm and across the biofilm/anode interface, and what determines the upper limit to biofilm thickness and catalytic activity (i.e ...

Anaerobic Degradation of Chloroanilines by Geobacter sp. KT5

Current Microbiology, 2019
A chloroaniline-degrading bacterial strain isolated from polluted sediment in the Mekong River was identified as Geobacter sp. KT5. The obtained isolate was found to utilize a wide range of trichloroanilines (TCAs), dichloroanilines (DCAs), monochloroanilines (MACs), and aniline as sources of carbon and energy.

The hydrogenases of Geobacter sulfurreducens: a comparative genomic perspective

Microbiology, 2005
The hydrogenase content of the genome of Geobacter sulfurreducens, a member of the family Geobacteraceae within the delta-subdivision of the Proteobacteria, was examined and found to be distinct from that of Desulfovibrio species, another family of delta-Proteobacteria on which extensive research concerning hydrogen metabolism has been conducted.

The electrifying physiology of Geobacter bacteria, 30 years on

2019
The family Geobacteraceae, with its only valid genus Geobacter, comprises deltaproteobacteria ubiquitous in soil, sediments, and subsurface environments where metal reduction is an active process. Research for almost three decades has provided novel insights into environmental processes and biogeochemical reactions not previously known to be carried ...
