Recently, as the interest in the accelerated global warming and the food shortage problem is increased, the concerns for microalgae as photosynthetic microorganisms are also increased. Specially, photosynthetic microalgae, Spriulina platensis have been an attractive source for $CO_2$ gas fixations and for a vast array of valuable nutritious compounds. In this paper, to culture the microalgal Spirulina platensis NIES 39 in a batch culture with high mass, optimal conditions for the culture temperature, initial pH, light intensity and concentration of carbon and nitrogen, were tested. At the most favorable culture condition, $35^{\circ}C$, initial pH 9.5, 4500 lux and carbon and nitrogen concentration of 16.8 g/L $NaHCO_3$ and 2.5 g/L $NaNO_3$, the excellent yields of 2.10 g/L biomass and 29.53 mg/L chlorophyll were obtained.
