采用气质联用仪测量 CO 2浓度,研究户外密闭条件下钝顶螺旋藻固定 CO 2的情况.实验结果表明,培养基中 NaHCO 3浓度较高及 pH 低于10时,试验第0~3天有大量 CO 2从培养基中溢出,之后藻液开始固定空气中CO 2.整个自制光生物反应器固定 CO 2量约为326 mg/(L.d),而单一反应器藻液固定 CO 2效率约为40%,其平均增重约0.14 g/(L.d).该技术能为净化燃煤工业废气中高浓度 CO 2提供理论依据,同时还可获得高经济价值的螺旋藻产品.

Gas Chromatograph Mass Spectrometer was used to evaluate the efficiency of CO 2 sequestration by the blue green alga Spirulina platensis in a closed photobioreactor cascade.It was found that Sp .plat-ensis culture emitted large quantity of CO 2 in the first a few days of the experiments,and then started CO 2 sequestration process.The emission of CO 2 was,presumably,caused by the combination of high concen-tration of NaHCO 3 and a pH value below 10.During theCO 2 sequestration process,the single photobiore-actor only assimilated ~ 40% of atmospheric CO 2 .Sp .platensis grew normally in this photobioreactor cascade with an average productivity of 0.14 g/L/d.The technology method provides a theoretical basis for purifing a high concentration of CO 2 in the coal-fired industries,and it can also achieve a high economic value of Spirulina products.Therefore,CO 2 sequestration by Spirulina is of great significance in the en-ergy industry,environmental protection and recycling economy.
