The Restorative Effects of Electron Mediators on the Formation of Electroactive Biofilms in Geobacter sulfurreducens [PDF]

Microorganisms
Electroactive biofilms (EABs) are essential for the performance of bioelectrochemical systems (BESs), but their formation in Geobacter, critically on conductive pili and exopolysaccharides, limits application under conditions where these components are ...

Quantification of microaerobic growth of Geobacter sulfurreducens. [PDF]

PLoS ONE, 2020
Geobacter sulfurreducens was originally considered a strict anaerobe. However, this bacterium was later shown to not only tolerate exposure to oxygen but also to use it as terminal electron acceptor.

Quantification of microaerobic growth of Geobacter sulfurreducens [PDF]

PLOS ONE, 2019
AbstractGeobacter sulfurreducenswas originally considered a strict anaerobe. However, this bacterium was later shown to not only tolerate exposure to oxygen but also to use it as terminal electron acceptor. Research performed has so far only revealed the general ability ofG.

Adaptive Evolution of Geobacter sulfurreducens in Coculture with Pseudomonas aeruginosa [PDF]

mBio, 2020
Interactions between microorganisms in mixed communities are highly complex, being either syntrophic, neutral, predatory, or competitive. Evolutionary changes can occur in the interaction dynamics between community members as they adapt to coexistence ...

Genome-wide analysis of the RpoN regulon in Geobacter sulfurreducens [PDF]

BMC Genomics, 2009
Background The role of the RNA polymerase sigma factor RpoN in regulation of gene expression in Geobacter sulfurreducens was investigated to better understand transcriptional regulatory networks as part of an effort to develop regulatory modules for ...

Importance of c-Type cytochromes for U(VI) reduction by Geobacter sulfurreducens [PDF]

BMC Microbiology, 2007
Background In order to study the mechanism of U(VI) reduction, the effect of deleting c-type cytochrome genes on the capacity of Geobacter sulfurreducens to reduce U(VI) with acetate serving as the electron donor was investigated.

Strategies for Reducing the Start-up Operation of Microbial Electrochemical Treatments of Urban Wastewater [PDF]

Energies, 2015
Microbial electrochemical technologies (METs) constitute the core of a number of emerging technologies with a high potential for treating urban wastewater due to a fascinating reaction mechanism—the electron transfer between bacteria and electrodes to ...

Anode biofilm transcriptomics reveals outer surface components essential for high density current production in Geobacter sulfurreducens fuel cells.

PLoS ONE, 2009
The mechanisms by which Geobacter sulfurreducens transfers electrons through relatively thick (>50 microm) biofilms to electrodes acting as a sole electron acceptor were investigated. Biofilms of Geobacter sulfurreducens were grown either in flow-through

Metabolic Profiling of Geobacter sulfurreducens during Industrial Bioprocess Scale-Up [PDF]

Applied and environmental microbiology, 2015
During the industrial scale-up of bioprocesses it is important to establish that the biological system has not changed significantly when moving from small laboratory-scale shake flasks or culturing bottles to an industrially relevant production level ...
