Electron transport across the cell envelope via multiheme c-type cytochromes in Geobacter sulfurreducens [PDF]
Frontiers in ChemistryExtracellular electron transfer (EET) enables certain microorganisms to respire using soluble and insoluble extracellular electron acceptors by transporting electrons across the cell envelope. Among these, G. sulfurreducens serves as a model organism for
