Live electrochemistry : Shewanella is an electrogenic microbe that has a significant content of c‐type cytochromes in its outer‐cell membrane. By using the specific binding affinity of nitric monoxide, we demonstrate the first electrochemical identification and electron‐transfer kinetics of cytochromes under living conditions. The results revealed an unusually efficient respiratory electron‐transfer chain at the cell/electrode interfaces.
