摘　　要：对极大螺旋藻(Spirulina maxima)和钝顶螺旋藻(S.platensis),在接种后第1~7 d通过不同时间添加Na2TeO3来施加Te(IV)胁迫,5种Te(IV)胁迫实验组的累计加Te浓度均为250 mg/L,结果表明:两种螺旋藻的最终生物量,从I^V组均呈增加趋势;其中IV、V组对S.platensis的生长有促进作用。利用动力学方程并结合胁迫强度的概念,对实验结果进行了合理的解释。Na2TeO3 was added into two species of Spirulina, Spirulina maxima and S. platensis, from one day to 7 day at different growing phases after inoculation, the cumulating concentration of Tellurium all is 250 mg/L. The results showed that the final biomasses of two species of Spirulina were increased from test set I to V. Test set IV and V accelerated the growth of S. platensis. The results were explained with both the equation of dynamics and the intensity of stress.
