Abstract

Abstract— Conditions were established which allow selective alteration of the pigment composition of Anacystis cells. Nitrate‐starvation at 28°C and 39°C resulted in the preponderance of chlorophyll a (Chi a) and that of phycocyanin (PC). In the case of starvation at 39°C strong correlation was observed between the disappearance of Chi a absorption and the appearance of an absorption band at 750 nm (P750) as the starvation proceeded. During regeneration the starved cells lost their P750 content. We show that P750 is quantitatively accounted for in the form of Chi a aggregates.
