Extracellular electron transfer powers flavinylated extracellular reductases in Gram-positive bacteria [PDF]
Proceedings of the National Academy of Sciences, 2019 Significance Strategies of energy metabolism are variable across the microbial world and fundamentally reflect distinct ecological dynamics. The complex electron transfer mechanisms that support many such processes take place in the cell membrane but can be wired to the exterior of the cell in some circumstances.

Electrochemical Enrichment and Isolation of Electrogenic Bacteria from 0.22 µm Filtrate
Microorganisms, 2022 Ultramicrobacteria (UMB) that can pass through a 0.22 µm filter are attractive because of their novelty and diversity. However, isolating UMB has been difficult because of their symbiotic or parasitic lifestyles in the environment.

Electron Uptake by Iron-Oxidizing Phototrophic Bacteria [PDF]
, 2014 Oxidation–reduction reactions underlie energy generation in nearly all life forms. Although most organisms use soluble oxidants and reductants, some microbes can access solid-phase materials as electron-acceptors or -donors via extracellular electron ...

Multi-heme Cytochromes in Shewanella oneidensis MR-1:Structures, functions and opportunities [PDF]
, 2015 Multi-heme cytochromes are employed by a range of microorganisms to transport electrons over distances of up to tens of nanometers. Perhaps the most spectacular utilization of these proteins is in the reduction of extracellular solid substrates ...

Characterization of Shewanella oneidensis MtrC: a cell-surface decaheme cytochrome involved in respiratory electron transport to extracellular electron acceptors [PDF]
, 2007 MtrC is a decaheme c-type cytochrome associated with the outer cell membrane of Fe(III)-respiring species of the Shewanella genus. It is proposed to play a role in anaerobic respiration by mediating electron transfer to extracellular mineral oxides that ...

Shewanella secretes flavins that mediate extracellular electron transfer [PDF]
Proceedings of the National Academy of Sciences, 2008 Bacteria able to transfer electrons to metals are key agents in biogeochemical metal cycling, subsurface bioremediation, and corrosion processes. More recently, these bacteria have gained attention as the transfer of electrons from the cell surface to conductive materials can be used in multiple applications.
