Growth and Nitrogen (N) Metabolizing Enzymes of Mesophilic and Psychrophilic Heterocystous Cyanobacteria—In Response to Temperature RegimesBy Shan Ahamed Tharifkhan, Deviram Garlapati, Darshana Arulraj, Uma Lakshmanan, Dharmar Prabaharan
Abstract: The increased NR & NiR activity, GS and nitrogenase activities at 25°C and 35°C in psychrophilic and mesophilic organisms indicates that the Arctic isolate is a psychrotolerant as it shows increased enzyme levels than its original temperature in which we isolated the organism though biomass was greater at 3°C. The biomass and enzyme data indicates cyanobacteria are the initiators of primary colonization in polar and alpine environments and are responsible …
