The growth parameters of all the three isolated Spirulina strains such as optical density, cell population, specific growth rate and doubling time of isolated Spirulina strains were studied in Zarrouk’s medium. A. The SpirulinaS1 strain showed highest growth in terms of optical density value at 560nm (1.870), cell population (5.30 CFU ml-1), specific growth rate (0.038 and doubling time (18.23) on 30th day. The effects of temperature, pH, light intensity and salinity on growth of Spirulina strains (S1, S2, and S3) and reference strain (CAS10) were determined in Zarrouk’s medium. The optimum temperature for the growth of all Spirulina strains was found to be 35°C followed by 40°C and 30°C. The highest biomass (0.308 mg ml-1) were recorded in Spirulina-S1 strain at 35°C.
