In this study microalgae using CCS(Carbon capture & store) technology and biodiesel conversion was investigated. Chlorella sorokiniana UTEX 2805, a heat-tolerant microalga, was cultured autotrophically in outdoor tubular photobioreactor in spring/fall and summer. Firstly assessment of the biomass production and photosynthetic activity using PAM(Pulse amplitude modulation) was performed under two temperature conditions (23℃, 36℃) in laboratory-scale. Consequently scale-up cultivation using 25L closed photobioreactor was performed in in outdoor conditions under photoautotrophic condition in spring/fall and summer. 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. |
