[Photogeneration of a 2-vector transmembrane proton gradient in Halobacterium halobium R1 cells].


Analysing 4 phases of light-dependent change of pH in cell suspension of H. halobium R1 it has been found that an increase of pH I when light is switched on and a decrease of pH II during further illumination are proportional to the light effect and are energy-dependent. Neutralization of these changes (phases III and IV) proceeds spontaneously in the… (More)
