Loss of photosynthetic activity in two blue-green algae as a result of osmotic stress.
A progressive loss of photosynthetic activity occurred when cells of Anacystis nidulans and Coccochloris peniocystis were incubated in increasing concentrations of osmotica from 0.2 to 0.7 M, and there was a release of pteridine from the cells proportional to the loss of photosynthetic activity.
