Dynamics of energy consumption during the growth of photosynthetic Halobacterium salinarum in populations of various age structures has been udied. Changes in the biosynthesis of bacteriorhodopsin, a key retinal containing protein of H.salinarum photosystem, were revealed. For several industrially ignificant strains, exponential accumulation of nonproliferating halobacterium cells, whose growth is limited by different modes of light exposure, was alculated. Various effects of proliferating and nonproliferating cells on bacteriorhodopsin biosynthesis rate were shown. Necessity to prevent influences f other growth limiting factors, except for energy consumption, during halobacterium cultivation was proved using cell population structuring model.
