Electrically conductive appendages produced by a number of bacteria
Geobacter sulfurreducens and its nanowires
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 consisting of Pelotomaculum thermopropionicum and Methanothermobacter thermoautotrophicus.[2] From physiological and functional perspectives, bacterial nanowires are diverse.[3][4][5] The precise role microbial nanowires play in their biological systems has not been fully realized, but several proposed functions exist.[3] Outside of a naturally occurring environment, bacterial nanowires have shown potential to be useful in several fields, notably the bioenergy and bioremediation industries.[6][7]
