Resum

Adenine, cytidine and guanosine nucleotides were supplied to cultures of Rhodopseudomonas capsulata under aerobic heterotrophic and phototrophic growth conditions. Aerobic growth is not affected by exogenous nucleotides (up to 10 mM) whereas phototrophic growth is strongly inhibited by adenine but not by guanosine or cytidine nucleotides. During phototrophic growth there is an inverse relationship between the concentration of exogenous adenine nucleotides and photopigment synthesis. There are no statistically significant differences between the inhibitory effect of AMP, ADP and ATP on the growth rate and bacteriochlorophyll synthesis since adenine nucleotides are incorporated into the cell as AMP by means of the phosphoribosyl transferase system.
