  • Title: [Features of transformation of phosphates in Rhodobacter sphaeroides chromatophores].
    Author: Goncharova NV, Kirichenko OG, Filatova LV.
    Journal: Prikl Biokhim Mikrobiol; 2004; 40(1):66-9. PubMed ID: 15029701.
    Abstract:
    We have found the ATP production in the Rhodobacter sphaeroides chromatophores illuminated by single short light flash, that is under conditions when the proton gradient formed as a result of electron transport after the second flash, is absent. The ATP synthesis was accompanied by the H2O2 formation. Simultaneous formation of H2O2 is indicative of the oxidative activation of phosphate during the ATP synthesis, as in the model systems with isolated chlorophyll. These data provide a theoretical background to the fitting of illumination parameters in both laboratory and industrial photobioreactors with photosynthetic bacteria used in biotechnological processes.
