| 摘 要： | 研究了不同碳酸盐碱度浓度条件下,钝顶螺旋藻OD560值、藻液pH值及碳酸盐碱度的变化。结果显示:培养4d后,4mg/L和8mg/L组生长缓慢且呈现下降趋势,OD560值均低于对照组,具有极显著差异(P<0.01),16mg/L和32mg/L组与对照组相比,无显著差异,而64mg/L组具有显著差异(P<0.05)。第6~12d,4mg/L、8mg/L组和16mg/LOD560值均低于对照组,具有极显著差异(P<0.01),32mg/L组无显著差异,而64mg/L组在6~8d,具有显著差异(P<0.05),且在第10~12d,与其它实验组和对照组相比,表现出极显著差异性(P<0.01)。NaHCO3与Na2CO3组成的缓冲体系,其pH值调节功能优于单一使用NaHCO3的对照组。在充气状态下,实验期间各组的碱度始终保持动态平衡。

| Abstract: | Spirulina platensis was cultivated,in comparative studies,using different concentrations of carbonate alkalinity.The influence of carbon concentrations of NaHCO3+Na2CO3 on the growth of Spirulina platensis was studied in this paper.The results showed that there were absolutely significant differences in the OD560 values between treatment groups of 4mg/L,8mg/L,16mg/L and the control(P<0.01).The OD560 values in these groups were lower than that of the control from the sixth day to the twelfth day.There was no... |
