Table 1 Changes in cofactor fluxes during CO₂ limitation. Moles of different cofactors or pathway intermediates generated per mole of glucose consumed, calculated using the different product yields as shown in Fig. 4 and stoichiometry of the pathways from phosphoenolpyruvate to the different fermentation products (i.e. the NADH/ATP-equivalents consumed/produced in glycolysis are not considered), as depicted in Fig. 1. Calculations based on the assumption that there is no difference in transhydrogenation by the malate shunt between 1 and 20% CO₂, and that 1 ATP-equivalent is formed in the conversion from phosphoenolpyruvate to pyruvate (Additional file 2)
