— The behavior of glow curves and of ferricyanide‐induced luminescence in photo‐synthetic bacteria is consistent with a model in which light is emitted when electrons return to oxidized reaction center chlorophyll from the primary acceptor. A number of observations can be explained if it is assumed that the chromatophore membrane potential provides part of the activation energy for the process. The model is tested by inducing light emission by the generation of potassium diffusion potentials in preilluminated Chromatium chromatophores.
