Microalgae are photosynthetic microorganisms being capable of converting carbon dioxide and water to organic macromolecules such as lipids, polysaccharides and proteins under light conditions. The polysaccharides can be hydrolyzed to obtain reducing sugars such as glucose, which could be used as bioethanol feedstocks. The lipids component (especially triacylglycerols) can be extracted and utilized as a biodiesel feedstock. In this study, the effects of enzymatic hydrolysis on the glucose production and subsequent lipid extraction from microalgal biomass (Chlorella vulgaris sp.) were investigated. The microalgal cells were hydrolyzed by cellulase and then their lipid fractions were extracted using various organic solvents such as hexane, methanol and chloroform. Optimal pH and temperature for the enzymatic hydrolysis were pH 4.8 and 50oC, respectively, and maximal efficiency was estimated at 85.3%. After the enzymatic hydrolysis, the lipid extraction yields by the organic solvents were improved by 1.23- to 1.73-fold depending on the solvents compared to those without the hydrolysis process.
