Biomass and lipid accumulation of three new screened microalgae with high concentration of carbon dioxide and nitric oxide.
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.
