Abstract This study aimed to achieve higher CO(2) consumption ability and lipid productivity of an indigenous microalgal isolate Scenedesmus obliquus CNW-N by a two-stage cultivation strategy. The microalga strain was first cultivated with 10\% CO(2) using a nutrient-rich medium to promote cell growth, which was followed by a nutrient-deficient condition to trigger lipid accumulation. The optimal biomass productivity, lipid productivity, and CO(2) consumption rate were 292.50mgL(-1)d(-1), 78.73mgL(-1)d(-1) (38.9\% lipid content per dry weight of biomass), and 549.90mgL(-1)d(-1), respectively. This performance is superior to the results from most of the related studies. Under the nutrient-deficient condition, the microalgal lipid was mainly composed of C16/C18 fatty acids (accounting for 89\% of total fatty acids), which is suitable for biodiesel synthesis.
