We studied the growth performance of Nannochloropsis oceanica IMET1 under various culture conditions, including different CO2 concentrations, temperature, or light intensities compared with that of N. gaditana CCMP526. When CO2 concentrations were changed, the growth rates of N. oceanica IMET1 and N. gaditana CCMP526 were the highest at a CO2 concentration of 2 vol%. N. oceanica IMET1 had a higher overall growth rate than that of N. gaditana CCMP526. The best growth rate occurred at 30°C, and higher growth rates were generally exhibited by N. oceanica IMET1 than N. gaditana CCMP526. The growth rate of N. oceanica IMET1 was higher than that of N. gaditana CCMP526 when light intensity was changed. These results indicate that N. oceanica IMET1 has better growth performance compared with that of N. gaditana CCMP526. The optimum growth conditions for N. oceanica IMET1 is CO2 concentration of 2 vol%, light intensity of 53 µmol/m2/s, and 30°C in modified BG11 medium.
