See http://www.geobacter.org/ or http://www.geobacter.org/ (copyrighted photos are coming from there) June 23, 2005 issue of Nature (Derek Lovley et al., UMass) The first Geobacter species was isolated from the Potomac River, just down stream from Washington D.C. in 1987. It uses metals, rather than oxygen, for respiration. The bacteria has now surprised the researchers with its ability to build conducting nanowires.

Geobacter – rump session CR ‘05 Jean-Jacques Quisquater Geobacter – rump session CR ‘05 Jean-Jacques Quisquater  Geobacter produces pilin-like filaments that function as nanowires to transfer electrons outside the cell onto insoluble electron acceptors, such as iron minerals and possibly electrodes. The filaments, which are only 3-5 nanometers in width (more than 10,000 times finer than a human hair), can extend more than 20 micrometers in length (more than 10 times the length of the cell).  The potential to biologically mass-produce fine, long conductive filaments may have applications in the development of nanoelectronic devices, sensors, and microbially based fuel cells.
