Abstract

Three species of indigenous microalgae species were isolated from an artificial lake. They were identified as Scenedesmus sp., through the molecular phylogenetic and morphological method and named SDEC-12, SDEC-13 and SDEC-14. To evaluate their tolerance to the harmful composition in the exhaust gas and the potential to produce biodiesel, they were cultured with 15% CO2 and 200 ppm NO. The SDEC-13 and SDEC-14 strains were able to grow well under 15% CO2 with the maximum biomass productivity of 0.087 and 0.090 g L(-1) d(-1), respectively. When cultured with 15% CO2, the three strains showed a similar total lipid content (25.7-28.25%) and the fatty acid of SDEC-14 strain showed the highest saturated level (76.59%). SDEC-13 was the only strain that could tolerate 200 ppm NO and 15% CO2, while its total lipid content remained unaffected by the NO, so the SDEC-13 strain had the potential to produce biodiesel with flue gas.
