Abstract: Spirulina platensis was cultivated in brewery effluent under different nutrient conditions. Results showed that Spirulina platensis biomass concentration could reach 2. 84g/L （dry biomass weight） in the brewery effluent at pH 9.0 with the addition of 2. 0g/L NaNO3, 6.6g/LNaHCO3, 0. 5g/LNaCl and 0. 25g/L k2HPO4. The culture was grown under air pump ventilation for eight days, whereas me light intensity was 2300 Lux and temperature 33℃ .The total of amount amino acids in the dry blomass was 37%.
