摘　　要：在温度为 ( 2 2± 1 )℃ ,盐度为 2 8的条件下 ,用不同浓度的NaHCO3( 0 ,1 0 0 ,2 0 0 ,40 0 ,80 0 ,1 2 0 0和 1 60 0mg/L)对青岛海洋大学微藻种质库保存的塔胞藻 (Pyramidomonassp.)、小球藻 (Chlorellaspp .)和新月菱形藻 (Nitzschiaclosterium )进行培养。实验结果表明 ,NaHCO3浓度对 3种海洋微藻生长的影响差异显著 ,经过 6d的培养 ,塔胞藻和小球藻的细胞浓度都在NaHCO3浓度为 1 2 0 0mg/L时达到最大值 ;新月菱形藻的细胞浓度在NaHCO3浓度为 40 0mg/L时达到最大值。marine algal species (Pyramidomonas sp., Chlorella spp.and Nitzschia closterium) coming from the Microalgae Culture Center, Ocean University of Qingdao were cultured in different solutions with graded levels of NaHCO 3 (0,100,200,400,800,1200 and 1600 mg/L) and under conditions of temperature of (22±1)℃ and salinity of 28. It is shown from the experiment results that the NaHCO 3 concentrations had significant influences on the growth of the 3 algal species, and after 6 days of culture, the optimal NaHCO 3 concentrations for the highest cell density of Pyramidomonas sp., Chlorella spp. and Nitzschia closterium were 1200 mg/L and 400 mg/L, respectively.
