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 (Gs) extracellular electron transfer (EET). These proteins are potential targets to improve EET and enhance bioremediation and electrical current production by Gs.

Methane production by Methanothrix thermoacetophila via direct interspecies electron transfer with Geobacter metallireducens

bioRxiv, 2023
Methanothrix is widely distributed in natural and artificial anoxic environments and plays a major role in global methane emissions. It is one of only two genera that can form methane from acetate dismutation and through participation in direct ...

Cytochromes in Extracellular Electron Transfer in Geobacter

Applied and Environmental Microbiology, 2021
Extracellular electron transfer (EET) is an important biological process in microbial physiology as found in dissimilatory metal oxidation/reduction and interspecies electron transfer in syntrophy in natural environments.

Microbial Reduction of Antimony(V)-Bearing Ferrihydrite by Geobacter sulfurreducens

Applied and Environmental Microbiology, 2023
Antimony is an emerging contaminant that shares chemical characteristics with arsenic. Metal-reducing bacteria (such as Geobacter sulfurreducens) can cause the mobilization of arsenic from Fe(III) minerals under anaerobic conditions, causing widespread ...

Structure of Geobacter OmcZ filaments suggests extracellular cytochrome polymers evolved independently multiple times

bioRxiv, 2022
While early genetic and low resolution structural observations suggested that extracellular conductive filaments on metal reducing organisms such as Geobacter were composed of Type IV pili, it has now been established that bacterial c-type cytochromes ...

Dissecting the Structural and Conductive Functions of Nanowires in Geobacter sulfurreducens Electroactive Biofilms

mBio, 2022
The low power generation of microbial fuel cells limits their utility. Many factors can affect power generation, including inefficient electron transfer in the anode biofilm.
