Extracellular electron transfer
Cellular and Molecular Life Sciences, 2001Results from several laboratories indicate that extracellular electron transfer may be a general mechanism whereby microoorganisms generate energy for cell growth and/or maintenance. Specifically, bacteria can use redox-active organic small molecules, generated outside or inside the cells, to shuttle electrons between reduced and oxidized compounds ...

Extracellular electron transfer of Methylophilus methylotrophs
Process Biochemistry, 2020Abstract Methylophilus methylotrophs, as representatives of C1 microbes, widely exist in the interface of hyperoxia–hypoxia environment and plays a key role in global carbon cycle. Most studies of Methylophilus were carried out under hyperoxic conditions, while it remains unclear how Methylophilus survive under oxygen-limited conditions.

Moving towards the enhancement of extracellular electron transfer in electrogens
World Journal of Microbiology and Biotechnology, 2023Electrogens are very common in nature and becoming a contemporary theme for research as they can be exploited for extracellular electron transfer. Extracellular electron transfer is the key mechanism behind bioelectricity generation and bioremediation of pollutants via microbes.

The Functional Mechanisms and Application of Electron Shuttles in Extracellular Electron Transfer
Current Microbiology, 2017Electron shuttles extensively exist in various environments. Some kinds of organic substances can be applied by microorganisms to produce electrons, and then the electrons can be transferred to other substances or microorganisms through electron shuttles, resulting in coexistence and interaction of diverse species of microbes.

Potential-dependent extracellular electron transfer pathways of exoelectrogens
Current Opinion in Chemical Biology, 2020Exoelectrogens are distinct from other bacteria owing to their unique extracellular electron transfer (EET) abilities that allow for anaerobic respiration with various external redox-active surfaces, including electrode and metal oxides. Although the EET process is known to trigger diverse extracellular redox reactions, the reverse impact has been long

Extracellular electron transfer features of Gram-positive bacteria
Analytica Chimica Acta, 2019Electroactive microorganisms possess the unique ability to transfer electrons to or from solid phase electron conductors, e.g., electrodes or minerals, through various physiological mechanisms. The processes are commonly known as extracellular electron transfer and broadly harnessed in microbial electrochemical systems, such as microbial biosensors ...

Extracellular electron transfer in microbial biocorrosion
Current Opinion in Electrochemistry, 2021Abstract Biocorrosion by microbial biofilms is also termed microbiologically influenced corrosion (MIC). For many decades in MIC research, people focused on corrosive metabolites. In the past decade, researchers started to apply bioenergetics to MIC science research.

Extracellular electron transfer via microbial nanowires
Nature, 2005Microbes that can transfer electrons to extracellular electron acceptors, such as Fe(iii) oxides, are important in organic matter degradation and nutrient cycling in soils and sediments. Previous investigations on electron transfer to Fe(iii) have focused on the role of outer-membrane c-type cytochromes.

A role for excreted quinones in extracellular electron transfer
Nature, 2000Respiratory 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.

Extracellular Electron Transfer and Biosensors
2017This chapter summarizes in the beginning our current understanding of extracellular electron transport processes in organisms belonging to the genera Shewanella and Geobacter. Organisms belonging to these genera developed strategies to transport respiratory electrons to the cell surface that are defined by modules of which some seem to be rather unique
