Cytochromes in Extracellular Electron Transfer in Geobacter. [PDF]

Appl Environ Microbiol, 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 ...

Electron transfer in multicentre redox proteins: from fundamentals to extracellular electron transfer. [PDF]

Biosci Rep
Multicentre redox proteins participate in diverse metabolic processes, such as redox shuttling, multielectron catalysis, or long-distance electron conduction. The detail in which these processes can be analysed depends on the capacity of experimental methods to discriminate the multiple microstates that can be populated while the protein changes from ...

In situ role of extracellular polymeric substances in microbial electron transfer by Methylomonas sp. LW13

Fundamental Research, 2021
Extracellular polymeric substances (EPS), produced by microorganisms, establish the functional and structural integrity of microbial biofilms. In biological wastewater treatments, the transformation of pollutants largely relies on microbial electron ...

Two Routes for Extracellular Electron Transfer in Enterococcus faecalis [PDF]

Journal of Bacteriology, 2020
The transfer of reducing power in the form of electrons, generated in the catabolism of nutrients, from a bacterium to an extracellular acceptor appears to be common in nature. The electron acceptor can be another cell or abiotic material.

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 ...

Electro-polarization of protein-like substances accelerates trans-cell-wall electron transfer in microbial extracellular respiration

iScience, 2023
Summary: Electrical stimulation has been used to strengthen microbial extracellular electron transfer (EET), however, the deep-seated reasons remain unclear.
