Algal biomass production and carbon fixation from flue gas

Algal biofuel has established as one of renewable energy. In this study, Nannochloropsis salina was cultured to test feasibility of biomass production and CO_2 fixation from flue gas. Firstly, cultivation was conducted under different light intensity. Results showed that the highest dry biomass of 1.25±0.061 g/L was achieved at light intensity of 10 klux, while the highest total lipids was 33.677 ±1.9% at light intensity of 15 klux.The effect of mercury on algae growth was also investigated, the algae growth was serious limited at the presence of mercury, and there was no any difference at the range of 10-50 ug/m~3. These results provide useful information for algal biomass production and CO_2 fixation from flue gas.
