Effect of various flue gas CO concentrations (5%, 10% and 14.1%) on growth rate and biochemical properties of a green microalga Scenedesmus obliquus was investigated. S. obliquus showed the highest biomass production and growth rate (0.36 g L and μ = 1.00 day), total inorganic carbon removal (35.8 mg L), lipid productivity (9.9 mg L day) and carbohydrate productivity (10.3 mg L day) with 14.1% CO after 8 days of cultivation. Fatty acid methyl ester analysis revealed that the palmitic and oleic acid contents were increased up to 5% and 7% with 14.1% CO, respectively. Application of flue gas CO enhanced the growth along with lipid and carbohydrate productivity of S. obliquus, which can be exploited for reducing the CO concentration.
研究了不同烟气CO浓度（5%、10%和14.1%）对绿色微藻斜生栅藻生长速率和生化特性的影响。在培养8天后，14.1% CO条件下斜生栅藻的生物量产量和生长速率最高（0.36 g·L且μ = 1.00 d⁻¹）、总无机碳去除量最高（35.8 mg·L）、脂质生产率最高（9.9 mg·L⁻¹·d⁻¹）以及碳水化合物生产率最高（10.3 mg·L⁻¹·d⁻¹）。脂肪酸甲酯分析表明，14.1% CO条件下棕榈酸和油酸含量分别增加至5%和7%。烟气CO的应用提高了斜生栅藻的生长以及脂质和碳水化合物生产率，这可用于降低CO浓度。
