Lipid extraction from Tetraselmis sp. microalgae for biodiesel production using hexane-based solvent mixtures |
| 초록 |
In this study, extraction performance using mixtures of hexane and polar solvents were evaluated to develop a more efficient method for large-scale lipid extraction from microalgae. The combination of hexane and methanol showed the highest fatty acid methyl ester (FAME) yield for lipids from Tetraselmis sp. The effects of extraction conditions including proportions of methanol to hexane, ratios of total solvent volume to dry biomass and extraction time on extraction yields were evaluated to determine cost-effective conditions providing higher lipid yields. Finally, the selected solvent mixture and optimal conditions were applied in larger scale extraction experiments with scale-up factors of 10, 50 and 100. FAME yields of large-scale extractions were almost consistent with increasing scale-up factors. The results of this study suggest that a mixture of hexane and methanol is a promising solvent for a large-scale lipid extraction from microalgae. |
