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 ...

Modular engineering to increase intracellular NAD(H/+) promotes rate of extracellular electron transfer of Shewanella oneidensis

Nature Communications, 2018
A bottleneck for the application of bioelectrochemical systems is the slow rate of extracellular electron transfer. Here the authors use a synthetic biology approach to redirect metabolic flux to NAD+ biosynthesis, which enhances the intracellular ...

A Membrane-Bound Cytochrome Enables Methanosarcina acetivorans To Conserve Energy from Extracellular Electron Transfer

mBio, 2019
Extracellular electron exchange in Methanosarcina species and closely related Archaea plays an important role in the global carbon cycle and enhances the speed and stability of anaerobic digestion by facilitating efficient syntrophic interactions.

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

Organic Microbial Electrochemical Transistor Monitoring Extracellular Electron Transfer

Advanced Science, 2020
Extracellular electron transfer (EET) denotes the process of microbial respiration with electron transfer to extracellular acceptors and has been exploited in a range of microbial electrochemical systems (MESs).

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

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.

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.

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.

Catabolic and regulatory systems in Shewanella oneidensis MR-1 involved in electricity generation in microbial fuel cells

Frontiers in Microbiology, 2015
Shewanella oneidensis MR-1 is a facultative anaerobe that respires using a variety of inorganic and organic compounds. MR-1 is also capable of utilizing extracellular solid materials, including anodes in microbial fuel cells (MFCs), as electron acceptors,
