Loss of Photosynthetic Activity in Two Blue-Green Algae as a Result of Osmotic Stress

Bernard Grodzinski

Brian Colman

Abstract: 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.

Anacystis nidulans Richt. was shown to assimilate glycolic acid, and uptake was light-stimulated. In the dark 90% of the glycolate taken up was oxidised to CO2. Both light and dark uptake was completely inhibited by α-hydroxysulphonates but was unaffected by isonicotinyl hydrazide. 3-(3,4-Dichlorophenyl)-1,1-dimethyl urea (DCMU) reduced the rate of light uptake but not to the uptake level of the dark control. Subjecting the algal cells to osmotic stress by incubation in 0.6 M mannitol for 1 h, which reduces the photosynthetic activity of this alga, causes an 80% reduction in both light and dark glycolate uptake although the uptake of glyoxylate, formate, acetate, and glycine is not markedly affected. Osmotic stress had no effect on the uptake and metabolism of glycolate by Anabaena flos-aquae (Lyngbye) Bred. and Oscillatoria sp. The activity of glycolate dehydrogenase in Anacystis was also reduced by osmotic shock while the activity of other enzymes was unaffected.
