Abstract: To optimize the basic formula of Spirulina medium,the effects of soda ash production wastes, sodium nitrate(NaNO3), potassium chloride (KCl), potassium dihydrogen phosphate (KH2PO4) on the phycocyanin content of Spirulina were determined using the response surface methodology (RSM) . Results showed that the optimal formula of Spirulina medium was soda ash production wastes 17 g, NaNO3 2 g, KCl 1 g, KH2PO4 1.6 g, which can achieve 0.269 3 mg·L-1 phycocyanin, 23% higher than that of the semi-synthetic medium used in outdoor cultivation.

Key words: Spirulina, response surface, medium optimization, phycocyanin
