Forty species of green microalgae (Chlorella spp., 36 species; Scenedesmus spp., 3 species; and Nannochloris sp.) arbitrarily chosen from the Korea Collection for Type Cultures were studied for their abilities of CO2 biofixation and lipid synthesis using coal-fired flue gas. Twelve species out of the forty species tested were selected based on biomass productivity and/or intracellular lipid content (mg fatty acids/g cell) using flask cultures with atmospheric CO2 and subsequent bubble-column cultures with 10% CO2 under in-door conditions. When further cultivated with the flue gas (12~15% CO2) from coal-power plant under out-door conditions, only two Chlorella species showed significant biomass productivities of 0.24 and 0.10 g cell/L/day, respectively. Lipid content (52~167 mg fatty acids/g cell) and fatty acids composition (mainly myristic acid, palmitic acid, myristoleic acid, stearic acid, oleic acid, linoleic acid, and linolenic acid) were largely varied depending on the species. This study indicates that many species of green microalgae have the ability to utilize CO2 at atmospheric and/or high concentrations but only two species have potentials for the biofixation and lipid production using CO2 in coal-power plants
