Abstract

Nitrate reductase activity in the thermal cyanobacteriumOscillatoria princeps was studied in vivo. Nitrite production by O. princeps grown microaerobically was four- to seven-fold higher than that in aerobic controls. Whereas microaerobic conditions caused instantaneous stimulation of nitrate reductase activity, addition of 40% O2 in air immediately inhibited it. Exposure of another cyanobacterium Anabaena doliolum to microaerobic conditions had no effect on NO 2 - production.
