Spectrum Study of Te(IV) stress on the growth of Spirulina maxima
Te(Ⅳ)对螺旋藻胁迫作用的光谱学研究

The effect of Te(IV) stress on the growth of Spirulina maxima has been studied via spectrum analysis. The Te(IV) adding time ranged from the 5th to 7th day and the accumulating Te(IV) concentration was from 450 to 650 mg/L. The absorption spectra showed that the intensity of typical absorption peak of S. maxima aqueous suspension decreased in the presence of Te(IV) stress. The fluorescence emission peaks which were excited at 440 and 580 nm showed that the intensity of peaks decreased in vivo. In contrast, the IR spectra of different groups have no significant difference because the energy transfer from phycobilisome was blocked in powder.
