The study of electrically conductive protein nanowires in Geobacter sulfurreducens has led
to new concepts for long-range extracellular electron transport, as well as for the …

Geobacter species specialize in making electrical contacts with extracellular electron
acceptors and other organisms. This permits Geobacter species to fill important niches in a …

Summary Long-range (> 10 μm) transport of electrons along networks of Geobacter
sulfurreducens protein filaments, known as microbial nanowires, has been invoked to …

Electrically conductive appendages from the anaerobic bacterium Geobacter sulfurreducens
were first observed two decades ago, with genetic and biochemical data suggesting that …

SUMMARY Type IV pili (T4P) are multifunctional protein fibers produced on the surfaces of a
wide variety of bacteria and archaea. The major subunit of T4P is the type IV pilin, and …

Long-distance extracellular electron transfer has been observed in Gram-negative bacteria
and plays roles in both natural and engineering processes. The electron transfer can be …

Dissimilatory metal-reducing bacteria (DMRB), such as Geobacter and Shewanella spp.,
occupy a distinct metabolic niche in which they acquire energy by coupling oxidation of …

Geobacter spp. can form a biofilm that is more than 20 μm thick on an anode surface by
utilizing the anode as a terminal respiratory electron acceptor. Just how microbes transport …

Transposon insertions in Geobacter sulfurreducens GSU1501, part of an ATP-dependent
exporter within an operon of polysaccharide biosynthesis genes, were previously shown to …

Extracellular electron transfer (EET) is the physiological process that enables the reduction
or oxidation of molecules and minerals beyond the surface of a microbial cell. The first …
