ATP requirement scan with nitrate as nitrogen source. The model predicted ammonium production, which was experimentally confirmed for growth of P. polymyxa ICGEB2008 on nitrate. Constraining the total ammonium production in the model to experimentally observed values, the model predicts a decrease in ethanol production to zero and an increase in acetate formation, which is in good qualitative agreement with experimental data. The simulations suggest that the maintenance ATP requirement per biomass almost doubles on nitrate when compared to ammonium nutrition
