Dynamics of cellular and extracellular cAmp in Anabaena flos-aquae (cyanophyta): intrinsic culture variability and correlation with metabolic variables
The production and extracellular release of cyclic adenosine 3':5'-monophosphate (cAMP) by the blue-green alga Anabaena flos-aquae (Lyngb.) Breb. varied greatly within and between active growth phase and stationary phase and under differing nutrient regimes. Enhanced cellular cAMP production was found in actively growing Anabaena inoculated into media deficient in nitrate or phosphate, or into fresh media containing non-limiting nutrient concentrations. In stationary phase Anabaena, but not actively growing cells, the concentrations of intracellular cAMP present in cells grown under a variety of nutrient regimes could be significantly correlated to (/sup 14/C)-bicarbonate uptake by an exponential relationship.
