The Mechanism of Lipids Extraction from Wet Microalgae Scenedesmus sp. by Ionic Liquid Assisted Subcritical Water The Mechanism of Lipids Extraction from Wet Microalgae Scenedesmus sp. by Ionic Liquid Assisted Subcritical Water

In this paper, the total sugar concentration, protein concentration, lipid yield and morphology characteristics of the algae residue were determined to explain the mechanism of lipids extraction from wet microalgae Scenedesmus sp. by ionic liquid assisted subcritical water. The results showed similar variation for the sugar, protein and lipid. However, the total sugar was more similar to lipids yield, so the results showed that the reaction between ionic liquid and cellulose and hemicellulose in cell wall was the most important step which determined the lipids extration directly. And the total sugar variation may be representing the lipids yield. For later lipids extraction, we can determine the total sugar concentration to predict the extraction end product
