Abstract

Cyanobacterial strains from family Rivulariaceae were isolated from various localities of District Allahabad, UP. Variations were observed with respect to photosynthetic rate, respiratory activity, carbohydrates and total soluble proteins amongst strains of Calothrix, Dichothrix and Gloeotrichia. The total N content and nitrogenase activity also varied in the three genera examined. The studies indicated the dominance of cyanobacteria belonging to family Rivulariaceae in the rice field soils and the diversity existed among these with respect to physiological parameters.
