Individual treatment effects: (A) electrode type during the 66-day operating period—the legends (Fig. 1A, B) are described as Xy–z, where X = electrode, y = ES and z = SFI, B best power curves based on a single point-estimation of the S-MFCs with different EM and ES; (C) effect of ES at 8 day SFI of SEC–MFC; (D) effect of SFI at 4 cm ES of SEC–MFC. E Power and internal resistance of S-MFC as a function of EM and ES
