摘　　要：基于微藻的光自养特性,研究了盐藻(Dunaliella salina)、亚心型扁藻(Platymonas ellip-tica)、球等鞭金藻(Isochrysis galbana)、牟氏角毛藻(Chaetoceros muelleri)、纤细角毛藻(Chaetoc-eros gracilis)、三角褐指藻(Phaeodactylum tricornutum)、新月菱形藻(Nitzschia closterium)和海水小球藻(Chlorellasp.)等8种海洋微藻细胞培养体系中的光衰减特性,并据此对30 L平板式光生物反应器中培养的8种海洋微藻分别采用恒定光和渐变光照射,检测两种光照条件下藻细胞的生长。通过回归分析,得到8种海洋微藻培养液中光照的衰减方程。在平板式光生物反应器中,渐变光照培养条件下8种微藻的细胞密度要高于恒定光照,结果表明渐变光照更适合于平板式光生物反应器中微藻的培养。Features of light intensity attenuation and its application to the culture of eight species of microalgae, i. e. Dunaliella salina , Platyrnonas elliptica , lsochrysis galbana , Chaetoceros rnuelleri , Chaetoceros gracilis , Phaeodactylurn tricornuturn , Nitzschia closteriurn and Chlorella sp. , in flat plate photobioreactor were investigated. Based on experimental results, the light attenuation could be described. The effects of stable and variable lighting on the growth of cell in a 30 L flat plate photobioreactor were examined. Results show that the program of light intensity was fit for the growth of microalgae in flat plate photobioreactor.
