Se stress in S. maxima and S. platensis at different growing phases was studied. Adding Se started from the 1st day to the 5st day and Se concentration increased every day. The cumulating Se concentration at the 7st day was 1000mg·L-1(stress of Se Ⅰ～Ⅴ). The growth of Spirulina, the absorption and bio-organization of Se were also discussed. It was indicated that the stress of Se Ⅰ～Ⅳ showed no significant effect; and the stress of Se Ⅴ showed obvious promotion. The total Se content and bio-organization rate of Se increased from Ⅰ to Ⅴ, The results were first explained by the stress intensity of Se.
