Structural Basis for Metallic-Like Conductivity in Microbial Nanowires
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 ...

Geobacter sulfurreducens can protect 304L stainless steel against pitting in conditions of low electron acceptor concentrations [PDF]
The effect of Geobacter sulfurreducens cells was studied on the electrochemical behaviour of 304L stainless steel, emphasizing the role of the soluble electron acceptor (fumarate). In fumarate-lacking media, the presence of G. sulfurreducens induced free

Limitations for Current Production in Geobacter sulfurreducens Biofilms
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
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 ...

Electricity Production byGeobacter sulfurreducensAttached to Electrodes [PDF]
ABSTRACTPrevious studies have suggested that members of theGeobacteraceaecan use electrodes as electron acceptors for anaerobic respiration. In order to better understand this electron transfer process for energy production,Geobacter sulfurreducenswas inoculated into chambers in which a graphite electrode served as the sole electron acceptor and ...
