Transcriptomic, Proteomic, and Bioelectrochemical Characterization of an Exoelectrogen Geobacter soli Grown With Different Electron Acceptors

Frontiers in Microbiology, 2018
The ability of Geobacter species to transfer electrons outside cells enables them to play an important role in biogeochemical and bioenergy processes.

Microbial electrocatalysis with Geobacter sulfurreducens biofilm on stainless steel cathodes [PDF]

, 2008
Stainless steel and graphite electrodes were individually addressed and polarized at−0.60V vs. Ag/AgCl in reactors filled with a growth medium that contained 25mM fumarate as the electron acceptor and no electron donor, in order to force the microbial ...

The genome of Geobacter bemidjiensis, exemplar for the subsurface clade of Geobacter species that predominate in Fe(III)-reducing subsurface environments.

BMC Genomics, 2010
Background Geobacter species in a phylogenetic cluster known as subsurface clade 1 are often the predominant microorganisms in subsurface environments in which Fe(III) reduction is the primary electron-accepting process.

Geobacter abundance in soil regulate by pH and iron-bearing minerals

Frontiers in Ecology and Evolution
As an electrogenic bacterium, Geobacter plays a crucial role in the geochemical cycles of arable soil. However, little is known about the existence of Geobacter and its impact factors in paddy soil and purple soil.

Effect of the semi-conductive properties of the passive layer on the current provided by stainless steel microbial cathodes [PDF]

, 2011
Geobacter sulfur reducens biofilms were formed under constant polarisation at −0.6 V vs. Ag/AgCl on stainless steel cathodes to catalyse the reduction of fumarate.

Geomonas oryzae gen. nov., sp. nov., Geomonas edaphica sp. nov., Geomonas ferrireducens sp. nov., Geomonas terrae sp. nov., Four Ferric-Reducing Bacteria Isolated From Paddy Soil, and Reclassification of Three Species of the Genus Geobacter as Members of the Genus Geomonas gen. nov.

Frontiers in Microbiology, 2019
In paddy soil, bacteria from the family Geobacteraceae have been shown to strongly contribute to the biogeochemical cycle. However, no Geobacteraceae species with validly published names have been isolated from paddy soil.

Forming electrochemically active biofilms from garden compost under chronoamperometry [PDF]

, 2008
Dimensionally stable anodes (DSA) were polarized at different constant potential values for several days in garden compost. After an initial lag period ranging from 1 to 10.5 days, the current increased fast and then stabilized for days.

Fluctuations in species-level protein expression occur during element and nutrient cycling in the subsurface. [PDF]

PLoS ONE, 2013
While microbial activities in environmental systems play a key role in the utilization and cycling of essential elements and compounds, microbial activity and growth frequently fluctuates in response to environmental stimuli and perturbations.

Ultra microelectrodes increase the current density provided by electroactive biofilms by improving their electron transport ability [PDF]

, 2012
Electroactive biofilms were formed from garden compost leachate on platinum wires under constant polarisation at -0.2 V vs. SCE and temperature controlled at 40 C.
