Geobacter Protein Nanowires

open access: yesFrontiers in Microbiology, 2019
The study of electrically conductive protein nanowires in Geobacter sulfurreducens has led to new concepts for long-range extracellular electron transport, as well as for the development of sustainable conductive materials and electronic devices with ...

Structural Basis for Metallic-Like Conductivity in Microbial Nanowires

open access: yesmBio, 2015
Direct measurement of multiple physical properties of Geobacter sulfurreducens pili have demonstrated that they possess metallic-like conductivity, but several studies have suggested that metallic-like conductivity is unlikely based on the structures of ...

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

open access: yes, 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 ...

Limitations for Current Production in Geobacter sulfurreducens Biofilms

open access: yesChemSusChem, 2013
AbstractDevices that exploit electricity produced by electroactive bacteria such as Geobacter sulfurreducens have not yet been demonstrated beyond the laboratory scale. The current densities are far from the maximum that the bacteria can produce because fundamental properties such as the mechanism of extracellular electron transport and factors ...

The triheme cytochrome PpcF from Geobacter metallireducens exhibits distinct redox properties

open access: yesFEBS Open Bio, 2018
Electrogenic bacteria, such as Geobacter, can couple the oxidation of carbon sources to the reduction of extracellular electron acceptors; such acceptors include toxic and radioactive metals, as well as electrode surfaces, making Geobacter a suitable ...

Phylogenetic analysis reveals an ancient gene duplication as the origin of the MdtABC efflux pump. [PDF]

open access: yes, 2020
The efflux pumps from the Resistance-Nodulation-Division family, RND, are main contributors to intrinsic antibiotic resistance in Gram-negative bacteria. Among this family, the MdtABC pump is unusual by having two inner membrane components.
