| Abstract | Lipid extraction from microalgae is of great interest as a future resource for various industries. However, the current extraction methods frequently involve the use of solvents that can be costly and environmentally harmful. In this study, an ultrasound-assisted extraction technique was proposed to enhance lipid extraction from Aurantiochytrium limacinum SR21 biomass. This technique optimizes the processes to eliminate the need for solvent, thereby helping alleviate environmental issues associated with the use of solvents. Under optimal conditions (NaCl concentration, 15% [w/v]; ultrasonic frequency, 45 kHz; temperature, 40 0C; and treatment time, 30 min), the lipid yield was 27.35%. Further, a comparison of lipid extraction yield under different frequencies at fixed positions within the ultrasonication bath revealed the highest lipid yield (39.52%) under a frequency of 45 kHz, followed by 28 kHz (20.36%) and 100 kHz (13.17%). Therefore, ultrasound-assisted extraction is promising for efficient solvent-free lipid extraction. |
