从各方面研究螺旋藻的最佳生产条件 ,以求得最优品质和最大产量 ,并对巨大螺旋藻所含粗蛋白、总糖、灰份、总有机物进行分析。确定巨大螺旋藻的最佳培养条件为 :Na HCO3的投加量为 13.0 g/L,光强为 2 0 0 0 lux～40 0 0 lux,光暗比为 9∶ 15 ,温度为 2 8℃～ 30℃ ,p H为 8～ 9 Spirulina from all aspects of the best production conditions, in order to obtain the best quality and maximum yield, and the giant spirulina crude protein, total sugar, ash, total organic matter analysis. The optimum culture conditions for the determination of Spirulina maxima were as follows: the dosage of Na HCO3 was 13.0 g / L, the light intensity was 200 lux ~ 40 0 ​​0 lux, the light to dark ratio was 9:15, the temperature was 28 ℃ ~ 30 ° C, p H is 8-9
