Twenty cyanobacterial cultures isolated from different geographical regions for India were characterized for growth and biochemical analysis. A wide variation was observed in total chlorophyll, total carbohydrates, total soluble proteins, total carotenoids, NR and GS activity among the cultures. There was a general trend of increase in different physiological parameters with increase in incubation time followed by decrease on further incubation. The diversity analysis based on similarity matrix also revealed immense distinctness and confirmed intrageneric variation among the cultures.
