Three species (Chlorella vulgaris, Scenedesmus obliquus and Ourococcus multisporus) with higher biomass yield were selected and cultured in wastewater amended with 15% CO2. C. vulgaris, S. obliquus and O. multisporus showed optimal specific growth rates (mu(opt)) of 1.37, 1.14 and 1.00 day(-1), respectively, and almost complete removal (˃99%) of nitrogen and phosphorus within 4 days. The highest specific lipid productivity was 0.164 g-lipids g-cell(-1) day(-1) and oleic acid was increased to 44% in C. vulgaris after 7 days of cultivation in the presence of CO2. It was concluded that C. vulgaris is a good potential source for the production of biodiesel coupled with nutrient removal from wastewater. (C) 2013 Elsevier B.V. All rights reserved.
