Bacterial nanowires
Appearance
Bacterial nanowires (also known as microbial nanowires) are electrically conductive appendages produced by a number of bacteria, most notably from (but not exclusive to) 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].
