Cytochromes in Extracellular Electron Transfer in Geobacter [PDF]

Applied and Environmental Microbiology, 2021
Extracellular electron transfer (EET) is an important biological process in microbial physiology as found in dissimilatory metal oxidation/reduction and interspecies electron transfer in syntrophy in natural environments. EET also plays a critical role in microorganisms relevant to environmental biotechnology in metal-contaminated areas ...

Long-distance electron transfer in a filamentous Gram-positive bacterium

Nature Communications, 2021
Long-distance extracellular electron transfer has been observed in Gram-negative bacteria. Here, Yang et al. show that a filamentous, unicellular Gram-positive bacterium is capable of bidirectional extracellular electron transfer, and forms centimetre ...

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
