Screening of Red Algae Filaments As a Potential Alternative Source of Eicosapentaenoic Acid

Abstract:

Lipids were extracted by a supercritical fluid extraction method from 10 species of filamentous red algae obtained from culture collections and their fatty acid compositions were determined. The fatty acid profiles of the 10 species were similar. The major fatty acids were 16:0, 20:4ω6 and 20:5ω3 (eicosapentaenoic acid, EPA), which amounted to over 70% of the total fatty acids. The highest EPA content (29.8 mg/L), as a percentage of total fatty acids, was produced by Liagora boergesenii filaments, which has good potential for EPA mass production in pilot plants.
