NO3-N is the most popular and safest nitrogen source to Spirulina, the suitable concentration is about 11mmol/L, which can speed the growth rate and reduce the cost of cultivation as well. NH4-N of the suitable concentration can enhance the growth of Spirulina,but overhigh concentration will cause the ammoniac toxicosis, the suitable concentration of NH4-N is about 1.27~2.57mmol/L.
NO3-N对螺旋藻是最为通用和安全的氮源,但添加浓度以11mmol/L左右最为适宜,既可满足藻体的最佳生长需求又可降低养殖成本;适宜浓度的NH4-N可促进螺旋藻的生长,浓度过高则会造成NH3中毒,NH4-N的添加量以1.27~2.57mmol/L范围最为适宜。
