As the price of conventional fossil fuels continues to escalate, so-called alternative fuels have become more attractive. Lipids from marine microalgae can be transformed into biodiesel fuel, a renewable energy. Recent reports revealed various detrimental effect of producing biofuels from crop (starch) biomass, as there would be a risk of greater food insecurity, higher food prices and shortage of land space. Dunaliella species belong to microalgae are known as massive lipid producers. Lipid extraction is an important process step to produce fuel cost effectively from microalgae. The purpose of this work was to optimize lipids extraction methods using solvent from Dunaliella tertiolecta. We tested various factors (kinds of solvents, amount of solvents, extraction temperature and time) were analyzed and compared for the lipid extraction efficiency. The solvent mixture of methanol and chloroform extracted lipids the most effectively and unexpectedly methanol alone was fairly good lipid extraction system from D. tertiolecta. |
