Genetic Manipulation of Desulfovibrio ferrophilus and Evaluation of Fe(III) Oxide Reduction Mechanisms

Microbiology Spectrum, 2022
The sulfate-reducing microbe Desulfovibrio ferrophilus is of interest due to its relatively rare ability to also grow with Fe(III) oxide as an electron acceptor and its rapid corrosion of metallic iron. Previous studies have suggested multiple agents for

Structure of Geobacter OmcZ filaments suggests extracellular cytochrome polymers evolved independently multiple times

eLife, 2022
While early genetic and low-resolution structural observations suggested that extracellular conductive filaments on metal-reducing organisms such as Geobacter were composed of type IV pili, it has now been established that bacterial c-type cytochromes ...

Ultrafast light-driven electron transfer in a Ru(II)tris(bipyridine)-labelled multiheme cytochrome [PDF]

, 2019
Multiheme cytochromes attract much attention for their electron transport properties. These proteins conduct electrons across bacterial cell walls, along extracellular filaments, and when purified can serve as bionanoelectronic junctions.
