     over 100 green-colored colonies were isolated from environmental samples when cultivating on a bg11 agar medium, and 4 strains showing different morphologies were selected based on light microscopic observation. among these strains, the microalgal species with the highest growth rate under 10% co2 was identified as ettlia sp. yc001 using an 18s rdna-based phylogenetic analysis and morphological comparison. the highest cell density of 3.10 g/l (based on dry cell weight) and biomass productivity of 0.19 g/l/d were obtained under 5% co2 after 16 days. the lipid content and productivity were also up to 42% of the dry cell weight and 80.0 mg/l/d, respectively. the color of theettlia sp. yc001 culture changed from green to red after a month due to the accumulation of certain carotenoids. therefore, it would seem that ettlia sp. yc001 is appropriate for mitigating co2 due to its high biomass productivity, and a suitable candidate for producing biodiesel and high-value products.
