The combined effect of superficial gas velocity, pH, initial phosphate concentration, and light intensity on cell growth was investigated for the mass production of cyanobacterial cells. The light intensity was manipulated to maintain a specific irradiation rate (qi) at a constant level for high cell density culture. The optimum condition for the batch culture was achieved at a superficial gas velocity of 2.0 cm/s, pH 7.0, and an initial phosphate concentration of 55 mg/l when the specific irradiation rate was controlled above 11.5 μmol/s/g dry cell. In this condition, the specific growth rate and cell productivity were 1.47 day-1 and 0.98 g dry cell/l/day, respectively.
