Living electronic transistors with tunable conductivity

Electroactive bacteria, like Shewanella oneidensis, can couple the oxidation of organic electron donors to the reduction of external conductive surfaces, such as minerals and electrodes, by utilizing multiheme cytochromes to carry charge from within the cell to external surfaces. Additionally, multiheme cytochromes fac...

Comparative transcriptomics and scarless genome editing uncover a periplasmic c-type cytochrome important for extracellular electron uptake in Thioclava electrotropha ElOx9T

The genetic basis for EEU in T. electrotropha is explored and a novel and potentially horizontally transferred mechanism for bacterial EEU is established, with implications for improved engineering of bioelectrochemical systems or use of novel electrotrophic microorganisms.
