• The pigment content in the blue-green alga Anacystis nidulans was found to be dependent upon CO_2 concentration during growth. In cells grown with 1% CO_2 in air the total pigment constituted 20.5% of the dry weight while it was only 11.1% of dry weight of cells grown in air (0.03% CO_2). This decrease in total pigment was found to be almost entirely ascribable to decrease in phycocyanin. Since light absorbed by phycocyanin has been shown to provide nearly equal rates of photoreactions I and II, the "CO_2 control" of phycocyanin is viewed as an effective means of regulation of the photoreactions without upsetting the balance of operation of the two photoreactions.
