Lipid　extraction　process　claimed　about　10-20%　of　the　total　cost　of　microalgal　fuels.　Cell　disruption　(bead　beater,　a　high-pressure　homogenizer,　ultrasoniaction,　etc)　followed　with　solvent　extraction　(hexane,　chloroform　and　methyl,　etc)　are　commonly　used　in　lab-　scale　experiments.　However,　it　is　time　consuming　and　costly　to　apply　these　methods　in　large-scale　production.　Recently,　some　innovative　methods,　such　as　microwave-assisted　process　and　enzyme　treatment　are　also　found　effective　in　lipid　extraction　from　wet　microalgae　biomass.　This　article　reviewed　the　current　techniques　commonly　used　in　lipid　extraction　from　wet　microalgae.　©　(2014)　Trans　Tech　Publications,　Switzerland.
