Lack of physiological evidence for cytochrome filaments functioning as conduits for extracellular electron transfer

mBio
Extracellular cytochrome filaments are proposed to serve as conduits for long-range extracellular electron transfer. The primary functional physiological evidence has been the reported inhibition of Geobacter sulfurreducens Fe(III) oxide reduction when ...

Importance of c-Type cytochromes for U(VI) reduction by Geobacter sulfurreducens

BMC Microbiology, 2007
Background In order to study the mechanism of U(VI) reduction, the effect of deleting c-type cytochrome genes on the capacity of Geobacter sulfurreducens to reduce U(VI) with acetate serving as the electron donor was investigated.
