We evaluated wastewater remediation and CO utilization potential of Chlorella minutissima from flue gas in a raceway pond, while synthesizing lutein and lipid for potential healthcare and biofuel application. A mix of 20% kitchen waste, 10 g L of poultry litter waste and 5% flue gas was maintained while cultivating the microalga. Complete removal of nitrate, nitrite and ammonium, 85% carbon and 91% phosphorus was observed. An average areal biomass productivity of 4.06 ± 0.12 g m day with a specific growth rate of 0.34 ± 0.03 day was observed within 9 days. Biomass productivity of 6.21 ± 0.16 g m day with a specific growth rate of 0.34 ± 0.03 day was achieved during winter. Furthermore, lipid content with appropriate fatty acid composition 1.04:1 (saturation:unsaturation) increased from 25% to 58%. Additionally, lutein productivity of 1.2 ± 0.08 mgL day, while utilizing 80.74 ± 0.07 mg L day of CO from 5% flue gas was obtained.
我们评估了从烟道气在跑道池中的小球藻去除废水和 CO 利用潜力，同时为潜在的医疗保健和生物燃料应用合成叶黄素和脂质。在培养微藻时，保持 20%厨房废物、10g/L 家禽垃圾和 5%烟道气的混合物。观察到硝酸盐、亚硝酸盐和铵的完全去除，85%的碳和 91%的磷。在 9 天内观察到平均面积生物量生产力为 4.06±0.12g/m2/天，特定生长率为 0.34±0.03/天。在冬季，实现了 6.21±0.16g/m2/天的生物量生产力和 0.34±0.03/天的特定生长率。此外，适当脂肪酸组成（1.04:1，饱和：不饱和）的脂质含量从 25%增加到 58%。此外，利用 5%烟道气中的 80.74±0.07mg/L 的 CO，获得了 1.2±0.08mgL/天的叶黄素生产力。
