The biomass and lipid productivity of Chlorella sp. MTF-15 cultivated using aeration with flue gases from a coke oven, hot stove or power plant in a steel plant of the China Steel Corporation in Taiwan were investigated. Using the flue gas from the coke oven, hot stove or power plant for cultivation, the microalgal strain obtained a maximum specific growth rate and lipid production of (0.827 d(-1), 0.688 g L(-1)), (0.762 d(-1), 0.961 g L(-1)), and (0.728 d(-1), 0.792 g L(-1)), respectively. This study demonstrated that Chlorella sp. MTF-15 could efficiently utilize the CO₂, NOX and SO₂ present in the different flue gases. The results also showed that the growth potential, lipid production and fatty acid composition of the microalgal strain were dependent on the composition of the flue gas and on the operating strategy deployed.
研究了中国钢铁公司台湾钢铁厂利用焦炉、热风炉或电厂废气通风培养的小球藻 MTF-15 的生物量和油脂生产力。利用焦炉、热风炉或电厂废气进行培养，微藻菌株获得了最大比生长速率和油脂产量（0.827 d(-1), 0.688 g L(-1)), (0.762 d(-1), 0.961 g L(-1)), 和 (0.728 d(-1), 0.792 g L(-1)). 本研究表明，小球藻 MTF-15 可以有效地利用不同废气中的 CO₂、NOX 和 SO₂。结果还表明，微藻菌株的生长潜力、油脂产量和脂肪酸组成取决于废气的组成和所采用的操作策略。
