Computational and Experimental Analysis of Redundancy in the Central Metabolism of Geobacter sulfurreducens

PLoS Computational Biology, 2005
Previous model-based analysis of the metabolic network of Geobacter sulfurreducens suggested the existence of several redundant pathways. Here, we identified eight sets of redundant pathways that included redundancy for the assimilation of acetate, and for the conversion of pyruvate into acetyl-CoA.

Lack of physiological evidence for cytochrome filaments functioning as conduits for extracellular electron transfer

mBio
Extracellular cytochrome filaments are proposed to serve as conduits for long-range extracellular electron transfer. The primary functional physiological evidence has been the reported inhibition of Geobacter sulfurreducens Fe(III) oxide reduction when ...

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

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.

Plugging in or Going Wireless:Strategies for Interspecies Electron Transfer [PDF]

, 2014
Interspecies exchange of electrons enables a diversity of microbial communities to gain energy from reactions that no one microbe can catalyze. The first recognized strategies for interspecies electron transfer were those that relied on chemical ...
