Bacterial Extracellular Electron Transfer Occurs in Mammalian Gut [PDF]
Analytical Chemistry, 2019 As a well-studied biochemical reduction process in environmental microbiology, extracellular electron transfer (EET) was recently discovered in bacteria closely related to human health, and orthologues of a flavin-based EET gene were found in the genomes of many species across Firmicutes, a major phylum in mammalian gut microbiota. However, EET has not

Bacterial extracellular electron transfer in plant and animal ecosystems
FEMS Microbiology Reviews, 2023 Abstract Extracellular electron transfer (EET) is a bioelectrochemical process performed by electrochemically active bacteria (EAB) found in host-associated environments, including plant and animal ecosystems and fermenting plant- and animal-derived foods. Through direct or mediated electron transfer pathways, certain bacteria use EET to

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.

The mechanisms of extracellular electron transfer [PDF]
, 2015 In bioelectrochemical systems (BESs) microbial activity facilitates electricity generation and product synthesis. Using the microbial process of extracellular electron transfer (EET) Shewanella and Geobacter species can respire using a solid terminal electron acceptor, such as an anode in BES.

Extracellular Electron Transfer Transcends Microbe-Mineral Interactions [PDF]
Cell Host & Microbe, 2018 Extracellular electron transfer (EET) allows microbes to drive their metabolism through interactions with minerals or electrodes. In recent work, Light et al. (2018) discover a specialized EET pathway in Listeria monocytogenes with homologs in pathogens and gut commensals, suggesting that EET plays important roles in diverse environments.

Modeling biofilms with dual extracellular electron transfer mechanisms [PDF]
Physical Chemistry Chemical Physics, 2013 Electrochemically active biofilms have a unique form of respiration in which they utilize solid external materials as terminal electron acceptors for their metabolism. Currently, two primary mechanisms have been identified for long-range extracellular electron transfer (EET): a diffusion- and a conduction-based mechanism.

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.
