The carbon dioxide (CO2) sequestration potential of two microalgae, Chlorella pyrenoidosa and Scenedesmus abundans was evaluated in a tubular batch photobioreactor with provision for continuous flow of 10% CO2 enriched air through the headspace. CO2 sequestration and biomass growth was affected by gas flow rate over the range 20-60ml/min and 40ml/min was found to maximize algal growth and CO2 sequestration. Moles of CO2 sequestered over 20h at a gas flow rate of 40ml/min was estimated using a novel rapid screening approach as 0.096 and 0.036, respectively, for C. pyrenoidosa and S. abundans. At this gas flow rate the maximum growth rate was 4.9mgL(-1)h(-1) and 2.5mgL(-1)h(-1) for C. pyrenoidosa and S. abundans, respectively. The CO2 sequestration and growth rate were comparable at height/diameter ratio of 8 and 16.
评估了两种微藻——蛋白核小球藻和普通小球藻在带有连续通入 10%CO2 富气的管状批式光生物反应器中的二氧化碳（CO2）固碳潜力。CO2 固碳和生物量生长受气体流速影响，在 20-60ml/min 的范围内，40ml/min 的流速被发现可使藻类生长和 CO2 固碳最大化。使用一种新的快速筛选方法，在 40ml/min 的气体流速下，20h 内固碳的摩尔数分别为 0.096 和 0.036，用于 C. pyrenoidosa 和 S. abundans。在此气体流速下，C. pyrenoidosa 和 S. abundans 的最大生长率分别为 4.9mgL(-1)h(-1)和 2.5mgL(-1)h(-1)。在高度/直径比为 8 和 16 时，CO2 固碳和生长速率相当。
