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 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 …

The family Geobacteraceae, with its only valid genus Geobacter, comprises
deltaproteobacteria ubiquitous in soil, sediments, and subsurface environments where metal …

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

Motility is an important virulence trait for many bacterial pathogens, allowing them to position
themselves in appropriate locations at appropriate times. The motility structures type IV pili …

Type IV pili are important virulence factors for many pathogens, including Pseudomonas
aeruginosa. Transcription of the major pilin gene—pilA—is controlled by the PilS-PilR two …

Biofilms of the electroactive bacterium Geobacter sulfurreducens were induced to grow on
graphite-rod electrodes under a potential of 0 V (vs Ag/AgCl) in the presence of acetate as …

Nitrogen gas (N2) fixation in the anode-respiring bacterium Geobacter sulfurreducens
occurs through complex, multistep processes. Optimizing ammonium (NH4+) production …

Microbial fuel cells (MFCs) are bioreactors that convert chemical energy stored in the bonds
of organic chemicals into electricity through biocatalysis of microorganisms. This chapter …

Abstract Type IV pili (T4P) are bacterial appendages used for cell adhesion and surface
motility. In metal-reducing bacteria in the genus Geobacter, they have the unique property of …
