报道了CeCl3能促进螺旋藻的放氧活性以及叶绿素和蛋白质的形成,而且其促进作用与NaHCO3的浓度有关。当螺旋藻生长在低NaHCO3培养液中,CeCl,对螺旋藻的促进作用比在高NaHCO,条件下更加明显。CeCl3培养的螺旋藻其吸收光谱和低温(77K)荧光发射光诣与对照有显著的差别,其藻蓝蛋白620nm的吸收峰高于对照,长波段的吸收峰从676nm转移至680nm,光系统1(PSI)和光系统Ⅱ(PSⅡ)的荧光发射比值(730nm/685~695nm)比对照高,而且藻体结构也发生了变化。
It was reported that CeCl3 can promote the oxygen-releasing activity of spirulina and the formation of chlorophyll and protein, and its promotion is related to the concentration of NaHCO3. When Spirulina was grown in low NaHCO3 medium, the promotion effect of CeCl on Spirulina was more obvious than that under high NaHCO. The absorbance spectra of CeCl3 cultured spirulina and its low temperature (77K) fluorescence emission were significantly different from those of the control. The absorption peak of phycocyanin at 620 nm was higher than that of the control, and the absorption band at long wavelength shifted from 676 nm to 680 nm. The fluorescence emission ratio (730nm / 685 ~ 695nm) of PSI and PSⅡ was higher than that of the control, and the structure of algal cells also changed.
