摘要:
为了实现微藻的烟气培养,从而降低培养成本,达到减排目的,以1株嗜碱绿球藻Chlorococcum alkaliphilus MC-1为研究材料,检测不同浓度CO2(5%、15%、50%、100%)对该藻光合放氧速率和生长的影响。结果显示,CO2浓度为5% 时,该藻光合放氧速率最大,平均值为117.60 μmol/(h·mg)(以单位时间、单位质量叶绿素的放氧量计),生长状态也最好,平均生物量产率、平均比生长速率、平均CO2固定速率均最大,分别为(0.063±0.001)g/(L·d)、(0.201±0.001) d-1、(0.188±0.002)g/(L·d),最高生物量浓度为(0.778±0.006)g/L。当CO2≥15%时,该藻光合作用和生长虽受到一定程度抑制,但当CO2浓度达到100%时,该藻光合放氧和生长状态依然保持较高水平,平均光合放氧速率为100.38 μmol/(h·mg),平均生物量产率、平均比生长速率、平均CO2固定速率分别为(0.048±0.002)g/(L·d)、(0.179±0.002) d-1、(0.090±0.004)g/(L·d),最高生物量浓度为(0.613±0.017)g/L。以上结果表明,该藻对高浓度CO2具有较强的耐受性,是1株极具潜力的烟气减排藻种。
