Flavin Electron Shuttles Dominate Extracellular Electron Transfer by Shewanella oneidensis

mBio, 2013
Shewanella oneidensis strain MR-1 is widely studied for its ability to respire a diverse array of soluble and insoluble electron acceptors. The ability to breathe insoluble substrates is defined as extracellular electron transfer and can occur via direct

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 ...

Redox linked flavin sites in extracellular decaheme proteins involved in microbe-mineral electron transfer [PDF]

, 2015
Extracellular microbe-mineral electron transfer is a major driving force for the oxidation of organic carbon in many subsurface environments. Extracellular multi-heme cytochromes of the Shewenella genus play a major role in this process but the mechanism

Adaptive bidirectional extracellular electron transfer during accelerated microbiologically influenced corrosion of stainless steel

Communications Materials, 2021
Microbiologically influenced corrosion is a major source of degradation of metals. Here, extracellular electron transfer is studied during pitting corrosion of stainless steel in the presence of an electroactive bacterium and a riboflavin electron ...

Exploring the biochemistry at the extracellular redox frontier of bacterial mineral Fe(III) respiration [PDF]

, 2012
Many species of the bacterial Shewanella genus are notable for their ability to respire in anoxic environments utilizing insoluble minerals of Fe(III) and Mn(IV) as extracellular electron acceptors.

Mechanisms of Bacterial Extracellular Electron Exchange. [PDF]

, 2016
The biochemical mechanisms by which microbes interact with extracellular soluble metal ions and insoluble redox-active minerals have been the focus of intense research over the last three decades. The process presents two challenges to the microorganism;

Bacterial extracellular electron transfer components are spin selective

The Journal of Chemical Physics, 2023
Metal-reducing bacteria have adapted the ability to respire extracellular solid surfaces instead of soluble oxidants. This process requires an electron transport pathway that spans from the inner membrane, across the periplasm, through the outer membrane, and to an external surface.

Isolation, identification and characterization of an electrogenic microalgae strain. [PDF]

PLoS ONE, 2013
Extracellular electron transfer involving microbes is important as it closely reflects the ability of cells to communicate with the environment. However, there are few reports on electron transfer mechanisms of pure microalgae and a lack of any model ...

The ‘porin-cytochrome’ model for microbe-to-mineral electron transfer [PDF]

, 2012
Many species of bacteria can couple anaerobic growth to the respiratory reduction of insoluble minerals containing Fe(III) or Mn(III/IV). It has been suggested that in Shewanella species electrons cross the outer membrane to extracellular substrates via ‘
