[The spectra of water-reabsorbing Spirulina maxima at different light intensity].
The freeze-dried cells of Spirulina maxima were resuspended in NaCl isotonic solution under the condition of darkness, natural light and culture illumination respectively. Their spectra were studied after the Spirulina maxima was treated for 2, 14 and 26 h respectively. The results indicated that the peak intensity decreased gradually at different light intensity but in the same time span. The peak intensity was the highest when Spirulina maxima was put in darkness, but lowest under culture illumination. The water-reabsorbing Spirulina maxima couldn't restore the normal photosynthesis under the dual stress of both water and light.
