Abstract

original image

Go with the flow:Shewanella is capable of transferring respiratory electrons to solid-state metal-oxides through physical contact (direct pathway) or by using electron shuttles (indirect pathway). We reveal, by using an electrochemical approach, that these pathways are switched depending on the redox state of the cytochromes.
