Dairy is one of the major industries causing water pollution with its large water consumption. In present study cyanobacterial species were isolated from dairy industries effluent and explored for removal of nutrients from dairy effluent simultaneously biomass produced again used for extraction of high value compounds. The percentage of nitrogen (N) and phosphate (P) reduction was 78.12%, 88.91%, 78.66% and 87.33%, 79.68%, 78.57% by spirulina, oscillatoria species and its consortium, respectively after 18 days. In case of high value compounds maximum amount of C-phycocyanin 0.431 mg/L and phycoerythrin 0.165 mg/L was extracted from oscillatoria species. The purification of the crude extract done by ammonium sulfate fractionation and Sephadex-G50 size exclusion chromatography. The lipid content from oscillatoria species was about 125.65 mg/l-1 which can be used for biofuel production.
