Chlorella sorokiniana UTEX 2805, a heat-resistant microalga, was cultured in outdoor tubular bioreactor in spring and summer. Particularly, an industrial flue gas generated by combustion of liquefied natural gas (LNG) and a sunlight were used for the economic production of biodiesel from the microalgal biomass. After performing a primary assessment of the biomass production under two temperature conditions (23℃, 36℃) in laboratory-scale, the cells were cultured in outdoor conditions under autotrophic condition in spring(March, 2014) and summer(July, 2014). As a result, C. sorokiniana showed high tolerance to flue gas and high temperature. In summer, the cell exhibited the remarkable lipid content (＞35% of dry biomass) under N-starvation conditions to accelerate an intercellular oil accumulation. C. sorokiniana will improve microalgal biodiesel production under high temperature in outdoor conditions. |
