The specific growth rate of phototrophic cultures of Rhodopseudomonas capsulata has a threshold dependence on the cytoplasmic membrane potential the major contributor to the protonmotive force. There is a strong correlation between the dependence of the membrane ionic current, the rate of ATP synthesis and the specific growth rate on the value of the cytoplasmic membrane potential.
