ABSTRACT
Lipids of Thamnidium elegans,Mortierella ramanninace,Rhizopus arrhizus,Pythium irregulare and Rhodotorulla aurantiaca were extracted by Soxhlet extraction,supercritical-CO 2 fluid extraction,acid-heating extraction and organic solvent extraction,respectively.Four extraction methods were evaluated on sample treatment,minimum sample quantity,requirements of apparatus,ability of treating sample and content of lipid.The components of fatty acids were analysed by gas chromatography.Soxhlet extraction can acquired maximum lipid content,but it took the most time.Supercritical-CO 2 fluid extraction and acid-heating extraction has a same lipid content which was lower than that of Soxhlet extraction.Acid-heating extraction was the most handy,and its ability to treat sample in a hour was the most powerful.Organic solvent extraction was less efficient.Acid-heating extraction was a simple and efficient method of fungi lipid extraction fitting to breed mutant strains that highly producting lipid and polyunsaturated fatty acids.
