Abstract
In an effort to identify suitable microalgal species for biodiesel production, seven species were isolated from various habitats and their growth characteristics were compared. The results demonstrated that a green alga Scenedesmus obliquus could grow more rapidly and synthesize more lipids than other six microalgal strains. S. obliquus grew well both indoors and outdoors, and reached higher μmax indoors than that outdoors. However, the cells achieved higher dry weight (4.36 g Lâ1), lipid content (49.6%) and productivity (183 mg Lâ1 dayâ1) outdoors than in indoor cultures. During the 61 days semi-continuous cultivation outdoors, high biomass productivities (450-550 mg Lâ1 dayâ1) and μmax (1.05-1.44 dayâ1) were obtained. The cells could also achieve high lipid productivities (151-193 mg Lâ1 dayâ1). These results indicated that S. obliquus was promising for lipids production in semi-continuous cultivation outdoors.
