Cell growth and lipid production of Chlorella minutissima in fed-batch culture was studied. Two carbon resources, such as CO2 and glucose were used to compare autotrophic and heterotrophic cultivate condition. For fed-batch cultivation, the feeding rate of seawater medium containing glucose was decided to be 0.5 ℓ/day of medium containing glucose. Autotrophic with CO2 showed the maximum cell growth of 9 (g-dry wt./L) and total lipid production of 15%. heterotrophic condition with glucose 10 g/ ℓ showed the maximum cell growth of 15 (g-dry wt./L) and total lipid production of 32%. Also, lipid profiles produced by gas chromatography analysis showed that lipid concentration of C17 and C18 composition is each 16%, 38%. This tells that Chlorella minutissima is a suitable bio-resource to produce the biodiesel. Accordingly, this study showed that the fed-batch cultivation with glucose is most effective for the large scale cultivation for biodiesel production with Chlorella minutissima.
