The ratio of adenine nucleotides in the cells of Rhodospirillum rubrum varies considerably depending upon the cultural and growth conditions.
There was no significant difference in the pool size of ATP, ADP and AMP comparing growing cells, which were cultivated aerobically in the dark, and cells, which were cultivated anaerobically in the light without substrate.
When the synthesis of ATP was inhibited or the ATP pool was lowered by high synthetic activity of the cells, the level of AMP was increased more drastically than that of ADP. This was true under anaerobic conditions in the light as well as in the dark. Under the same conditions in aerobically grown dark cultures, ADP and AMP increased to nearly the same extent.
In aerobic light cultures the relative content of ATP can be higher than in aerobic dark cultures or in anaerobic light cultures. In the former pyruvate accumulated.
With antimycin A (40 ~g/ml) the ATP pool decreased in aerobic light cultures.
