EFFECTS OF HIGH CO2 CONCENTRATION ON GROWTH AND PHOTOSYNTHESIS OF SPIRULINA MAXIMA

摘要: 以极大螺旋藻作为实验材料,研究了高CO2浓度对极大螺旋藻的生长和光合作用效应,结果表明在高光强下(400μmolm-2s-1),高浓度CO2对其生长和光合作用有明显的影响,高浓度CO2培养下,螺旋藻的比生长速率是低浓度CO2培养的12倍;而在低光强下,高浓度CO2对其生长和光合作用无明显影响.两种不同CO2浓度和光强下培养的极大螺旋藻,在不同的生长时期,分别测定其P-I曲线,结果表明低光强下培养的极大螺旋藻,在5d、8d、11d,两者的Ik、α值均无显着差异,Pmax在第5d、11d差异不显着,但在第8d有显着差异.而在高光强培养条件下,第8、11d通高浓度CO2培养的极大螺旋藻,其Pmax、α值明显大于通低浓度CO2培养的极大螺旋藻,但两者在第5d无明显差异.Abstract: Growth and photosynthesis of Spirulina maxima grown in different CO2 concentrations and light intensities had been studied. In low light intensity, no significant differences were observed in specific growth rate when the algae were cultured in different CO2 concentration, and so were the Pmax, α and Ik. But in high light intensity, the algae grew faster in high CO2 concentration compared to low CO2 concentration, the specific growth rate being 0 394d-1,0 475d-1,respectively. No significant differences were observed in Pmax, α and Ik in the fifth day. However, significant differences in Pmax, α were found in the eighth and eleventh day.
