Lack of physiological evidence for cytochrome filaments functioning as conduits for extracellular electron transfer [PDF]

mBio
Extracellular cytochrome filaments are proposed to serve as conduits for long-range extracellular electron transfer. The primary functional physiological evidence has been the reported inhibition of Geobacter sulfurreducens Fe(III) oxide reduction when ...

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.

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.

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 ...

Adaptive bidirectional extracellular electron transfer during accelerated microbiologically influenced corrosion of stainless steel

Communications Materials, 2021
Microbiologically influenced corrosion is a major source of degradation of metals. Here, extracellular electron transfer is studied during pitting corrosion of stainless steel in the presence of an electroactive bacterium and a riboflavin electron ...

Extracellular electron transfer powers flavinylated extracellular reductases in Gram-positive bacteria [PDF]

Proceedings of the National Academy of Sciences, 2019
Significance Strategies of energy metabolism are variable across the microbial world and fundamentally reflect distinct ecological dynamics. The complex electron transfer mechanisms that support many such processes take place in the cell membrane but can be wired to the exterior of the cell in some circumstances.

Spatiotemporal organization of membrane protein controls bacterial extracellular electron transfer [PDF]

Nature Communications
Extracellular electron transfer (EET) is essential for electroactive microbes’ physiology and biotechnological applications. Many such microbes are Gram-negative bacteria, in which EET must cross two membranes and the periplasm, necessitating spatial and
