Its growth temperature range is from 6 to 40 and optimum temperature range is about 24 . when the temperature is reduces to 22 immediately ( from 35 to 13 ) , it can still grow . after it is frozen at - 18 , it still can restore to life , which is a feature that other spirulina do not have . compared with the introduced spirulias platensis , it shows low temperature characteristic and wide temperature ecological amplitude 其生长的温度范围是6 - 40 ；最适温度为24左右；在温度骤降幅度达22时(从35降到13 )依然能够生长；该藻在- 18冰冻之后依然可以复生；其对低温的适应特性是引进的钝顶螺旋藻和极大螺旋藻所不具备的。
