MORPHOLOGICAL AND BIOCHEMICAL CHARACTERIZATION OF CYANOBACTERIAL ISOLATES FROM BIOLOGICAL SOIL CRUST OF RAJASTHAN, INDIAAbstract
The BSC sample was collected at four sites from the arid region of Rajasthan and these isolates were characterized based on morphological and biochemical parameters. We have to isolate both heterocysts and non-heterocysts cyanobacterial species. Oscillatoria tenuis species showed maximum chlorophyll accumulation and Phormium showed maximum carotenoids compared to heterocystous forms. The soluble protein content is high in Non-heterocystous Phormium and Oscillatora curviceps and lowest in heterocystous Nostoc linckia. Heterocystous forms Nostoc commune and Anabaena variabilis were synthesizing high carbohydrates compared to nonheterocytstous forms. Highest nitrogenase activity in Nostoc linckia isolated from Achorl site.
