Abstract
The fluorescence yield of whole cells of the photosynthetic bacteria Chromatium, Rhodospirillum rubrum, and Rhodopseudomonas spheroides was measured in low intensity light as a function of redox potential under anaerobic conditions at pH 8.0. The titration curves were fit by the Nernst equation for a one-electron reaction. The midpoint potentials were −160 mV and −145 mV, respectively, for Chromatium and R. rubrum. The R. spheroides showed less reversibility and is characterized by midpoints of −65 mV and −90 mV for the oxidative and reductive titrations.
