Bacterial nanowires (also known as microbial nanowires) are electrically conductive appendages produced by a number of bacteria most notably from the Geobacter and Shewanella genera. [ 1 ] [ 2 ] Conductive nanowires have also been confirmed in the oxygenic cyanobacterium Synechocystis PCC6803 and a thermophilic , methanogenic coculture ...
OmcS nanowires (Geobacter nanowires) are conductive filaments found in some species of bacteria, including Geobacter sulfurreducens, where they catalyze the transfer of electrons. They are multi heme c-Type cytochromes localized outside of the cell of some exoelectrogenic bacterial species, serving as mediator of extracellular electron transfer ...
Geobacter is a genus of bacteria. Geobacter species are anaerobic respiration bacterial species which have capabilities that make them useful in bioremediation. Geobacter was found to be the first organism with the ability to oxidize organic compounds and metals, including iron, radioactive metals, and petroleum compounds into environmentally benign carbon dioxide while using iron oxide or ...

Microbial electrochemical technologies (METs) use microorganisms as electrochemical catalyst, merging the microbial metabolism with electrochemical processes for the production of bioelectricity, biofuels, H 2 and other valuable chemicals. [1] Microbial fuel cells (MFC) and microbial electrolysis cells (MEC) are prominent
Geobacter sulfurreducens and its bacterial nanowires. Geobacter sulfurreducens is a rod-shaped microbe with a gram-negative cell wall.Geobacter is known as a type of bacteria that is able to conduct levels of electricity, and the species G. sulfurreducens is also known as “electricigens” due to their ability to create an electric current and produce electricity.

A nanowire is a nanostructure in the form of a wire with the diameter of the order of a nanometre (10 −9 m). More generally, nanowires can be defined as structures that have a thickness or diameter constrained to tens of nanometers or less and an unconstrained length.
In the future, cable bacteria may play a role in increasing the efficiency of microbial fuel cells deployed in sedimentary environments. Cable bacteria have also been found associated with a bioelectrochemical system that enhances the degradation of marine sediment contaminated by hydrocarbons [ 25 ] and thus may play a role in future oil spill ...
