a Calculated ∆rG310 K for the metabolic network of microbial consortia as a function of acetate concentration, normalized for e-mol transferred per reaction. Process conditions considered were: temperature of 310.15 K, ionic strength of 0.08 M, PH2 of 1.05 atm, PCO2 of 0.6 atm, PCO of 0.45 atm, concentration of other metabolites of 0.001 M and pH 5. b Thermodynamic potential factor calculated for all reactions as a function of pH. Solid lines represent FT calculated using a ∆Gp of 57.5 kJ/mol of ATP. Dashed lines represent the upper and lower boundary of FT when using a ∆Gp of 45 and 70 kJ/mol of ATP, respectively. The upper and lower boundaries are shown only for acetate-reducing reactions and the chain elongation reaction
