Abstract:

大气中CO2浓度增加造成的全球变暖已成为一个严峻的环境问题,利用微藻生物固碳法减排CO2正成为研究热点.本文以普通小球藻(Chlorellavulgaris,FACHB-1227)为研究对象,采用SE无碳培养基,在沿程曝气型套管式光生物反应器中通入含不同体积分数CO2(5%、10%、15%和20%)的模拟烟气培养小球藻,培养周期为17天,以细胞密度和平均固碳速率为检测指标,研究模拟烟气下普通小球藻生长情况及固碳能力.实验结果表明当模拟烟气中CO2体积分数为10%时,普通小球藻的细胞密度达到最大值8.76×106cells/mL,相比于5%组、15%组和20%组分别提高了54.23%、66.86%和76.97%;其平均固碳速率达最大值30.18mg/(L？d),较5%组、15%组和20%组分别提高了57.27%、70.89%和81.91%.可见,在模拟烟气中CO2体积分数为10%时,普通小球藻的生长情况和固碳性能最好.
