- Recently, microalgae have been considered as a feedstock for various types of alternative biofuel production (e.g. biohydrogen, bioethanol, biodiesel), because of their ability to accumulate high oil in their body and rapid growth rate by photosynthetic apparatus. Especially, marine microalgae also have the unique physiological characteristics to thrive under the diverse marine environments, so they are attractive sources for researchers to study new useful compounds and chemicals. Among marine microalgae, Phaeodactylum tricornutum is not only satisfied with high biomass productivity as well as reasonable oil content, but also a superior producer of PUFA (poly-unsaturated fatty acid) such as eicosapentaenoic acid (EPA, 20:5w3) and docosahexaenoic acid (DHA, 22:6w3). In order to maximize biomass productivity as well as eliminate light inhibition and limitation, specific light uptake rate was examined. Then, obtained value of specific light uptake rate was used effectively during the experiment. The other conditions (temperature, light intensity, nitrate depletion) were also altered to investigate their effects on production of fatty acid. The variation in fatty acids quantity and quality were analyzed by gas chromatograph. Under nitrate depletion with 2 days, the accumulated total fatty acids in cell body were increased from 14.0% to 39.4%. In contrast, under low light condition (at 50 mE/m2/s), nitrate depletion had no significant effect on fatty acid content. Also, a dramatic increase in PUFA (from 63.1% to 71.4% of the total fatty acid, during 4 days) was observed under low temperature. The result of this study is the strong evidences that support the potential of improving biodiesel and bioactive compound production from microalgae by manipulating growth conditions.
