  3. Around 40 ; the neutral curve obtained by the growth rates of the temperature fluctuation has a ringlike curve separated from the main branch of nachtsheim s calculation by velocity fluctuation at the lower grashof number side ; and its phase velocity is close to the maximum mean velocity where the critical layer of the eigenmode locates. the thermal fluctuation decays rapidly as the nondimensional frequency above 0. 4, so that it means that the coupling effect between instability wave generated by buoyancy fluctuation and velocity waves by invicid instability seems weak enough for their critical layers in the range of the nondimensional frequency

  6. 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
