Structural Basis for Metallic-Like Conductivity in Microbial Nanowires

mBio, 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 ...

The triheme cytochrome PpcF from Geobacter metallireducens exhibits distinct redox properties

FEBS 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 ...

Garden compost inoculum leads to microbial bioanodes with potential-independent characteristics [PDF]

, 2013
Garden compost leachate was used to form microbial bioanodes under polarization at 0.4, 0.2 and +0.1 V/SCE. Current densities were 6.3 and 8.9 A m2 on average at 0.4 and +0.1 V/SCE respectively, with acetate 10 mM.

Link Between Capacity for Current Production and Syntrophic Growth in Geobacter species

Frontiers in Microbiology, 2015
Electrodes are unnatural electron acceptors, and it is yet unknown how some Geobacter species evolved to use electrodes as terminal electron acceptors.
