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 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.
Instead, electric bacteria "breathe" metals instead of oxygen, which effectively results in both an intake of and excretion of electrical charges. [2] Some electric bacteria: Shewanella, which makes protein nanowires [3] Geobacter, which makes protein nanowires out of pilin [4] Methanobacterium palustre [5] Methanococcus maripaludis [6]
Experts sounded an alarm about the potentially lethal risks of creating mirror bacteria, synthetic organisms in which the molecular structure found in nature is reversed.
