Abstract: Biodiesel from microalgae is considered as the only renewable biofuel that has the potential to displace traditional petroleum-derived transport fuels and meet the global demand for transport fuels. However, its more widespread use is limited by high cost of microalgal cultivation. Industrial waste gas(flue gas) contains not only a lot of CO2, but also considerable sulfur oxides(SOx) and nitrogen oxides(NOx), so utilization of flue gas for microalgal cultivation to reduce the cost of microalgal biodiesel has atracted more and more attention. In this paper, the mechanism of absorption and metablization of CO2, SO2 and NOx by microalgae and the applications of flue gas in cultivation of microalgae were reviewed. Based on the unique capacity of microalgal suspention culture system in utilization of CO2, SO2 and NOx, the idea of simultaneous lipid production, CO2 fixation, SO2 and NOx removal by microalgae was established.

Key words: microalgae, flue gas, biodiesel, CO2 fixation, SO2 removal, NOx removal
