Table 7 Comparison of predicted amperages and power outputs of the three modes

	Conditions	Biomass growth rate (h^-1)	Electron (mmol gDW^-1 h^-1)	Amperage (A gDW^-1)	Coulombic efficiency (CE%)	Theoretical limit of the power output (W gDW^-1)
MET	5% of maximum growth rate	0.01432	97.40	2.610	81.17%	2.166
DET			81.68	2.189	68.07%	0.5604
DET with flavin secretion			81.98	2.197	68.31%	0.5738

Note: Cytochrome c and NADH have different standard potentials. The power density for the mixed mode was calculated by summing the power contributions from the riboflavin and FMN-involved DET and the cytochrome c-dependent DET; that is, the current outputs of DETs were multiplied by their appropriate voltages, respectively.
