The cultivation of microalga is drawing attention as solution for elimination of CO2 in fuel gas from industries and plants. The microalgae have capability to reduce CO2 and to produce various pharmaceuticals, and cosmetics and biofuels. Before application of microalge to industry for reduction of CO2, the effect of fuel gas was considered. The fuel gas contains high CO2, NOx, and fine dust. In this study, Haematococcus pluvialis was cultured in outdoor condition which was maintained at 2 2℃ of temperature, 50~200 mol photon/m²s of light intensity and 25L polymer bag type of photo-bioreactor. H. pluvialis was cultivated with 20 % fuel gas and 80 % air a week for adaptation to high level CO2 and NOx at first, and then fuel gas concentration was increased up to 50 %. And because the H. pluvialis has two stage, green vegetative stage and red cyst stage, the experiments were conducted under each two stage conditions, green vegetative stage and red cyst stage. At the red cyst stage, there was no big difference between fuel gas and pure CO2. The dry cell weight was obtained almost 2 g/L and astaxanthin was 70 mg/L for 50 days. However, at the green vegetative stage, the induction of H. pluvialis was inhibited by fuel gas.
