Effect of sonication at different ultrasonic frequencies on the quality and quantity of fatty acids of the oil of Chlorella vulgaris

In order to investigate the effect of sonication on the fatty acids of alga oil, oil of Chlorella vulgaris was extracted by sonication at 20, 40, 60 and 80 kHz. Oil extracted by refluxing alga cells in n-hexane was used as control. Probable changes in the structures of the fatty acids were investigated using gas chromatography and Fourier transform infrared spectroscopy (FT-IR). The retention profiles of the...
