Control of ATP metabolism in Rhodopseudomonas spheroides

Growth kinetics and cell composition (RNA, protein, bacteriochlorophyll and adenosyl nucleotides phosphate) of Rhodopseudomonas spheroides in photosynthetic growing culture with continuous illumination and various intermittent light regimens have been examined. The results indicated that bacteriochlorophyll and RNA were controlled by ATP level and protein synthesis and growth by the ability of the cells to utilize intracellular ATP.
