Impact of varying Phosphate concentration on some local isolates of Cyanobacteria 

Sneha Kumari & Shikha Chaudhury


Three isolates, Phormidium mucicola, Lyngbya limnetica, Anabaena circinalis were collected from wetland area of Saharsa district. Axenic culture of each isolate was prepared. Effect of different concentration of Phosphate was observed on 3rd, 6th, 9th, 12th and 15th day on each isolate. The phosphate concentration were prepared from K2HPO4.3H2O and the concentrations were 0.5%, 2.5%, 4.5% and 6.5%. Maximum growth was observed at a concentration of 2.5% and minimum of 0.5% concentration. In each concentration, growth increased gradually.
