469333 Macroemulsion Mixture Assisted Organic Solvent Extraction of Algal Lipids from Unconcentrated Algal Culture
This study demonstrates a procedure for lipid extraction from microalgae culture using a mixture of macroemulsion and organic solvents at room temperature. This method does not require harvesting and dehydration of the algal biomass. The effects of extraction variables were investigated. The results showed that the macroemulsion mixture assisted solvent extraction method extracted 83-87% of total recoverable lipids at a mixing time of less than 1 min. No significant differences in terms of distribution of fatty acid profile have been obtained when compared to the Bligh and Dyer method. Evaluation of energy consumption indicates a substantial reduction in extraction costs compared to other methods.
