Unraveling the Electron Transfer in Cupriavidus necator – Insights Into Mediator Reduction Mechanics
Publikováno v:
ChemElectroChem, Vol 11, Iss 14, Pp n/a-n/a (2024)
Abstract Cupriavidus necator, despite lacking direct electron transfer capabilities, demonstrates efficient reduction of various redox mediators in oxygen‐free cultivation within bioelectrochemical systems. This study investigates the reduction sit
