Abstrakt: The effect of heating at 65°C for 20 min on the absorption spectra and kinetics of the dark recombination of charges separated between photoactive bacteriochlorophyll and quinone acceptors was studied in dry films of bacterial photosynthetic reaction centers (RCs), RC films in polyvinyl alcohol, and trehalose. A pronounced protective effect of trehalose against pheophytinizaiton of molecules bacteriochlorophylls in RC structure and in maintaining their higher photochemical activity was found.
