The cyanobacterium Spirulina platensis is an attractive alternative source of the pigment chlorophyll, which is used as a natural color in food, cosmetic, and pharmaceutical products. In the present investigation, the influence of light intensity and pH for Spirulina platensis growth, protein and chl a content were examined. In the present investigation the production of Spirulina platensis was optimized in terms of biomass and metabolites. The dry weight of Spirulina platensis was 0.91g/500ml and protein and Chlorophyll a content were 64.3% and 13.2mg/gm respectively at pH 9. At 5 Klux light intensity the dry weight of Spirulina platensis was 0.85g/500ml while protein content and Chlorophyll a were 64.3% and 9.8mg/gm respectively
