Extracellular Electron Transfer of Weak Electricigens in the Presence of a Competing Electron Acceptor

Journal of the Electrochemical Society, 2023
To maximise microbial electroactivity in bioelectrochemical systems, soluble electron acceptors are typically omitted as they compete with the electrode.

Humic Substances and Extracellular Electron Transfer

2012
Humic substances (HS) are redox-active organic molecules that are present in virtually all environments. A wide variety of bacteria including Fe(III)-reducers, sulfate reducers, methanogens, and fermenting bacteria can reduce HS and in a second, abiotic step, the reduced HS can transfer their electrons to terminal electron acceptors such as poorly ...

Bacterial extracellular electron transfer in bioelectrochemical systems

Process Biochemistry, 2012
Abstract Bioelectrochemical systems (BES), typically microbial fuel cells (MFCs), have attracted increasing attention in the past decade due to their promising applications in many fields, such as bioremediation, energy generation and biosynthesis. Current-generating microorganisms play a key role in BES.

Extracellular Electron Transfer in Bioelectrochemically Active Microorganisms

2020
Bioelectrochemical systems, such as microbial fuel cells and microbial electrosynthesis, are promising technology for energy generation and organic compound production. In the bioelectrochemical systems, extracellular electron transfer is essential in which c-type cytochrome, electrically conductive nanowires, and electron shuttles play key roles. This

Microbial electrocatalysis: Redox mediators responsible for extracellular electron transfer

Biotechnology Advances, 2018
Redox mediator plays an important role in extracellular electron transfer (EET) in many environments wherein microbial electrocatalysis occurs actively. Because of the block of cell envelope and the low difference of redox potential between the intracellular and extracellular surroundings, the proceeding of EET depends mainly on the help of a variety ...

Directed Biofabrication of Nanoparticles through Regulating Extracellular Electron Transfer

Journal of the American Chemical Society, 2017
Biofabrication of nanomaterials is currently constrained by a low production efficiency and poor controllability on product quality compared to chemical synthetic routes. In this work, we show an attractive new biosynthesis system to break these limitations. A directed production of selenium-containing nanoparticles in Shewanella oneidensis MR-1 cells,

Extracellular Electron Transfer in Methanogenic Archaea

2019
Three decades ago, respiration with a solid electron donor or acceptor would have made great science fiction. Now we know that “electroactive” microorganisms perform this on a daily basis in various anaerobic habitats. These electroactive microorganisms are classified by their ability to utilize solid electron donors or acceptors outside of the cell in

A role for excreted quinones in extracellular electron transfer

Nature, 2000
Respiratory processes in bacteria are remarkable because of their ability to use a variety of compounds, including insoluble minerals, as terminal electron acceptors. Although much is known about microbial electron transport to soluble electron acceptors, little is understood about electron transport to insoluble compounds such as ferric oxides.

Translating Extracellular Electron Transfer Activities with Organic Electrochemical Transistors

Journal of Visualized Experiments
Extracellular electron transfer (EET) is a process through which certain microorganisms can transfer electrons across their cell membranes to external electron acceptors, linking cellular metabolism to their environment. While Geobacter and Shewanella have been the primary models for EET research, emerging studies reveal that EET-active species are ...
