The Role of Exopolysaccharides in Direct Interspecies Electron Transfer
Frontiers in Microbiology, 2022 Direct interspecies electron transfer (DIET) is an effective mechanism for microbial species to exchange electrons cooperatively during syntrophic metabolism. It is generally accepted that DIET is mainly mediated by electrically conductive pili and outer

Direct Electron Transfer of Enzymes Facilitated by Cytochromes. [PDF]
ChemElectroChem, 2019 AbstractThe direct electron transfer (DET) of enzymes has been utilized to develop biosensors and enzymatic biofuel cells on micro‐ and nanostructured electrodes. Whereas some enzymes exhibit direct electron transfer between their active‐site cofactor and an electrode, other oxidoreductases depend on acquired cytochrome domains or cytochrome subunits ...

Recent Advances in the Direct Electron Transfer-Enabled Enzymatic Fuel Cells [PDF]
Frontiers in Chemistry, 2021 Direct electron transfer (DET), which requires no mediator to shuttle electrons from enzyme active site to the electrode surface, minimizes complexity caused by the mediator and can further enable miniaturization for biocompatible and implantable devices.
