In this paper we report that CeCl3 could accelerate the synthesis of chlorophyll a and protein in spirulina platensis. and enhance the activity of oxygen evolution. We also found that the accelerations of CeCl3 in spirulina platensis culture solution of low NaHCO3 were more than in culture solution of high NaHCO3, therefore it was related to the concentration of NaHCO3 The absorption spectrum and low temperature (77 K) fluorescence emission spectrum of spirulina platensis with CeCl3 treated were significantly different from their controls,*** absorption peak of phycocyanin at 620 nm was higher than that of the *** absorption peak at the long wave region migrated from 676 to 680 nm, and its fluorecence emission ratios (730 nm/685～695 nm) of photosystem I(PSI) to photosystem Ⅱ(PS Ⅱ) were also higher than those of the control; the pitch of the spiral algal body became shorter, and induced structural changes too.
