摘　　要：根据藻类的生长特点设计了一个容积为10.0L的光生物反应器,其长×宽×高分别为320mm×80mm×390mm。利用该反应器进行螺旋藻培养实验,采用响应面法对其培养条件进行优化研究,建立以藻体干重为响应值,以光照强度、通气量、培养时间和装液量为自变量的二次多项式数学模型。培养条件优化后螺旋藻最终干重为1.298g/L。实验结果表明,所设计的反应器能很好地满足藻类生长,其培养产率也明显提高。A new photo-bioreactor was designed basing on the growth trait of the algae.The volume of the reactor was 10.0L,the length,width and height was 320,80,390mm,respectively.Used the reactor to culture Spirulina platensis,and employed the response surface methodology to optimize the fermentation conditions.Then,researched the optimization concentration levels and the relations between these factors and building up a quadratic regression equation with dry weight as the dependent,light intensity,air flow,time of cultivation and volume of medium as independent.Under the optimistically conditions,the final dry weight was 1.298g/L.According to the experiment results,the photo-bioreactor designed was fit to cultivate the algae.
