    Supercritical fluid extraction. The advantages of supercritical fluid extraction compared with liquid extraction are that it is relatively rapid because of the low viscosities and high diffusivities associated with supercritical fluids. The extraction can be selective to some extent by controlling the density of the medium, and the extracted.

    Lipid Extraction From Spirulina Sp. And Schizochytrium

    Microalgae are one of the most promising feedstocks for biodiesel production due to their high lipid content and easy farming. However, the extraction of lipids from microalgae is energy intensive and costly and involves the use of toxic organic solvents. Compared with organic solvent extraction, supercritical CO 2 SCCO 2 has demonstrated advantages through lower toxicity and no solvent.
