Genome-Based Taxonomic Rearrangement of the Order Geobacterales Including the Description of Geomonas azotofigens sp. nov. and Geomonas diazotrophica sp. nov.

Frontiers in Microbiology, 2021
Geobacterales is a recently proposed order comprising members who originally belonged to the well-known family Geobacteraceae, which is a key group in terrestrial ecosystems involved in biogeochemical cycles and has been widely investigated in ...

Adaptive Evolution of Geobacter sulfurreducens in Coculture with Pseudomonas aeruginosa

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 ...

The relay network of Geobacter biofilms [PDF]

Energy & Environmental Science, 2016
The finding of cytochrome complexes in the external matrix of electricity producing biofilms supports the proposal of a new functional model, in which electrons expelled by cells are conducted to the collecting electrode along a redox network interconnected by semiconducting pilus fibres.

Design Principles for a New Form of Bioelectrical Nanonetwork Based on Cellular Nanowires

Journal of Sensor and Actuator Networks
Nanotechnology continues to advance rapidly, revealing previously unexplored directions in nanoscale communications. Biological and electromagnetic nanonetworks—established communication paradigms at the nanoscale—have shifted interest toward the middle ...

Formation of nanoscale elemental silver particles via enzymatic reduction by Geobacter sulfurreducens

, 2008
Geobacter sulfurreducens reduced Ag(I) (as insoluble AgCl or Ag+ ions), via a mechanism involving c-type cytochromes, precipitating extracellular nanoscale Ag(0). These results extend the range of metals known to be reduced by Geobacter species and offer

Quantification of microaerobic growth of Geobacter sulfurreducens

PLOS ONE, 2019
Abstract 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.

Rational engineering of Geobacter sulfurreducens electron transfer components: a foundation for building improved Geobacter-based bioelectrochemical technologies [PDF]

Frontiers in Microbiology, 2015
Multiheme cytochromes have been implicated in Geobacter sulfurreducens extracellular electron transfer (EET). These proteins are potential targets to improve EET and enhance bioremediation and electrical current production by G. sulfurreducens. However, the functional characterization of multiheme cytochromes is particularly complex due to the co ...

Proteogenomic monitoring of Geobacter physiology during stimulated uranium bioremediation [PDF]

, 2009
Implementation of uranium bioremediation requires methods for monitoring the membership and activities of the subsurface microbial communities that are responsible for reduction of soluble U(VI) to insoluble U(IV).

Biochemical Capacitance of Geobacter Sulfurreducens Biofilms

ChemSusChem, 2015
AbstractAn electrical model able to decouple the electron pathway from microbial cell machinery impedance terms is introduced. In this context, capacitance characteristics of the biofilm are clearly resolved. In other words, the model allows separating, according to the advantage of frequency and spectroscopic response approach, the different terms ...
