Method The specific ATP production rate was calculated from the products formed in the chemostat in detectable amounts (CO2, acetic acid (HAc) and biomass).
Comments Comparison of the magnitude of the ATP-dissipating processes with the capacity of the potassium- uptake systems shows that at an intermediate growth rate of 0.2 h^-1, the difference in ATP flux between the two strains is 19 mmol ATP×g^-1×h^-1 (0.32 mmol ATP×g^-1× min^-1).
