Naturally occurring freshwater microalgae were mass cultivated in continuous mode at a large-scale facility. From June 2014 to August 2015, biomass productivity, lipid content, and calorific value data were obtained from two 675.0 m2 raceway ponds. The collected biomass had an overall average productivity of approximately 7.0 g dry weight/m2/day and a lipid content of 12.2%. Ultimate analysis incorporated with thermal analysis indicated that the average calorific value was 17.5 MJ/kg. The dominant genera found were Chlorella, Coelastrella, Acutodesmus, and Pseudopediastrum. This pilot-scale study demonstrated the potential of microalgal biomass produced on a largescale as a biofuel under Korean geoclimatic conditions.
