A heat-tolerant microalgae Chlorella sorokiniana UTEX 2805 was cultured in outdoor tubular photobioreactor in spring and summer. For the economic biodiesel production from microalgae biomass through outdoor cultivation, an industrial flue gas as a CO2 source and a sunlight were used. A primary assessment of the biomass production under two different temperature (23℃, 36℃) was performed in laboratory-scale. And then, the C. sorokiniana was cultured under autotrophic outdoor condition in spring (March, 2014) and summer (July, 2014). As a result, C. sorokiniana showed remarkable resistance to flue gas and high temperature. Particularly, the cell exhibited the high lipid content (＞35% of dry biomass) under nitrogen starvation condition in summer and accelerated intercellular oil accumulation. Therefore C. sorokiniana will be used as a useful source for biodiesel production under high temperature outdoor conditions. |
