Sun light is most important factor for maintaining high cell density and total lipid production. Chlorella sp. was grown under mixotrophic conditions with a methanol by batch cultivation, controlling light intensity: continuous illumination and 12:12 hr(light:dark) illumination at 450 μE/m2. s optimal light intensity, and no light as heterotrophic growth. Continuously light
illumination showed much higher cell concentration as 6.9 g-dry wt./L for overall cultivation periods. While 12:12 hr(light:dark) cyclic light illumination showed 6.1 g-dry wt./L of maximum cell concentration and 18.6% (w/w) of total lipid production. Heterotrophic cultivation had the
lowest cell concentration as 1.6 g-dry wt./L. It implies that light cycle illumination would maintain relatively high cell concentration as well as total lipid production, while could be and for scale-up the system in outdoor cultivation.
