A method for the determination of confidence limits for the P/2e- ratio for chosen values of ymaxatp form the results of continuous culture experiments.

A model is described, which allows the determination of 95% confidence limits for the maintenance coefficient and the efficiency of oxidative phosphorylation for chosen values of the growth yield for ATP corrected for energy maintenace (YmaxATP). As experimental data the specific rates of substrate consumption, product formation and oxygen uptake in chemostat cultures at various growth rates are use.
