Eox and Ered, oxidation and reduction peak potentials, respectively, derived from the representative CVs in Fig. 4.
Corresponding phenazine concentration related to the representative CV in Fig. 4, not to the averaged phenazine concentrations from Fig. 3.
—, no phenazines were detected or a redox peak was not distinguishable.
