Spirulina is one of the most explored cyanobacteria. Since ancient time it is being used as source of protein. The aim of the present study is to develop the low-cost medium from sugar mill effluent (SME) for mass production of S. platensis and producing high amounts of protein and create pollution free environment. Microalgae S. platensis, culture offers an interesting step for wastewater treatments, because they provide a tertiary bio treatment coupled with the production of potentially valuable protein biomass, which can be used for several purposes. Microalgae cultures offer an elegant solution to tertiary and quandary treatments due to the ability of microalgae to use inorganic nitrogen and phosphorus for their growth. And also, for their capacity to remove heavy metals, as well as some toxic organic compounds, therefore, it does not lead to secondary pollution. The low-cost SME medium was formulated by supplementing rice mill effluent with various concentrations of carbon, phosphorus and nitrogen sources. The best cellular growth of S. platensis was observed in SME medium with NaHCO3 (10. g L-1) as carbon source, and K2HPO4 (0.30 g L-1) as a phosphorus source and NaNO3 (2.00 g L-1) as a nitrogen source, with trace of FeSO4 and EDTA at pH 9.5. Parameters like specific growth rate, dry weight, chlorophyll, lipid and protein content were measured.
