Extracellular Electron Transfer and Biosensors

2017
This 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

Bacterial Vesicles Mediate Extracellular Electron Transfer

Environmental Science & Technology Letters, 2019
Many Gram-negative bacteria are known to release outer membrane vesicles (OMVs) into the surrounding environment during normal growth; OMVs perform diverse biological and environmental functions (e...

Nanomaterials Facilitating Microbial Extracellular Electron Transfer at Interfaces

Advanced Materials, 2020
AbstractElectrochemically active bacteria can transport their metabolically generated electrons to anodes, or accept electrons from cathodes to synthesize high‐value chemicals and fuels, via a process known as extracellular electron transfer (EET). Harnessing of this microbial EET process has led to the development of microbial bio‐electrochemical ...

Extracellular electron transfer systems fuel cellulose oxidative degradation

Science, 2016
The fuel for fungal enzymes Many microorganisms have specialized enzymes to target and break down plant biomass. In fungi, these enzymes, called lytic polysaccharide monooxygenases (LPMOs), partner with electron transfer partners to oxidatively cleave the polysaccharide backbone of lignocellulosic polymers.

Accelerated Destruction of Passive Film and Microbial Corrosion of 316L Stainless Steel via Extracellular Electron Transfer.

Angewandte Chemie
The dense passive film on 316L stainless steel is the key in its corrosion resistance. Its interactions with an electroactive biofilm are critical in deciphering microbial corrosion.

Extracellular electron transfer features of Gram-positive bacteria

Analytica Chimica Acta, 2019
Electroactive 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 ...

Potential-dependent extracellular electron transfer pathways of exoelectrogens

Current Opinion in Chemical Biology, 2020
Exoelectrogens 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

Biochar assists phosphate solubilizing bacteria to resist combined Pb and Cd stress by promoting acid secretion and extracellular electron transfer.

Journal of Hazardous Materials, 2023
Microorganisms have difficulty surviving and performing remediation functions in mixed systems with high concentrations of Pb and Cd. Biochar has the potential to assist microorganism remediation as an excellent adsorbent for heavy metals. In this study,
