[Localization of energy generators in methane oxidizing bacteria]

Cytochromes a, b and c, and their quantitative distribution in the cells, were studied by means of differential spectra in obligate methane oxidizing bacteria, Methylosinus trichosporium with the serine pathway of methane carbon assimilation and Methylomonas agile with the ribulose phosphate pathway of methane carbon assimilation, and different types of topography of intracytoplasmic membranes. The membranes are involved in processes of coupled respiration which was confirmed by cytochemical reactions employed for studying the terminal step of the electron transport chain and Mg2+-stimulated ATPase.
