title: [Mass-energy balance of the growth of phototropic purple bacteria].
abstract: The principles of the theory of mass-energy balance of the growth of cellular populations are described. Based on this theory, the effect of biochemical parameters of cell metabolism on the efficiency of phototrophic growth of bacterial culture was studied. The metabolism of phototrophic bacteria was subdivided into constructive and energetic partial metabolisms. The stoichiometric coefficients describing the energetics of the two metabolism types were calculated. An equation system of the mass-energy balance for the flows of reductivity, high-energy bonds, and protons--carriers of the transmembrane electrochemical potential was derived. Equations for biomass quantum yield were obtained. The calculated yield values are in agreement with experimental data.
