New lipid-extraction technologies involve innovations in acoustics, sonication. mesoporous nanomaterials, and amphiphilic solvents. For example. SRS Inc. designs solvent systems specifically for a given algae strain and has a test facility in New Mexico. Supercritical fluids (methanol or CO2) are being evaluated for lipid extraction, and supercritical fluid extraction (SFE) has been reported to be safer and faster than traditional hexane extraction (10).
