Forming microbial anodes under delayed polarisation modifies the electron transfer network and decreases the polarisation time required. [PDF]
, 2012 Microbial anodes were formed from compost leachate on carbon cloth electrodes. The biofilms formed at the surface of electrodes kept at open circuit contained microorganisms that switched their metabolism towards electrode respiration in response to a ...

Mechanisms of Phenazine-Mediated Extracellular Electron Transfer by Pseudomonas aeruginosa [PDF]
, 2020 Extracellular electron transfer (EET), the process whereby cells access electron acceptors or donors that reside many cell lengths away, enables metabolic activity by microorganisms, particularly under oxidant-limited conditions that occur in ...

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 ...

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

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

A severe reduction in the cytochrome C content of G eobacter sulfurreducens eliminates its capacity for extracellular electron transfer [PDF]
, 2015 The ability of Geobacter species to transfer electrons outside the cell enables them to play an important role in a number of biogeochemical and bioenergy processes.

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.
