Lipid and fatty acids extraction from the cyanobacterium Spirulina

Ratana Chaiklahana,*, Nattayaporn Chirasuwana, Veara Lohab, Boosya Bunnagc

ABSTRACT:     Lipid extraction from Spirulina using a single stage extraction at 30 C showed that a sample-solvent ratio of 1:10 and an extraction time of 120 min gave the highest total fatty acid (TFA) yield, whereas a ratio of 1:5 was suitable for a multistage extraction. An increase in extraction temperature resulted in higher lipid and TFA yields. Increasing the extraction temperature from 30 C to 60 C decreased the extraction time and increased the yield of lipid and TFA in the solvent by approximately 69% and 55%, respectively. In order to increase the extraction yield of the lipid and TFA, multistage cross-current extraction was implemented. Seven-stage extraction at 30 C resulted in 85% TFA recovery, whereas only a three-stage extraction was needed to obtain the same level of TFA at 60 C. Lipid extracted from Spirulina contained approximately 21% linoleic acid and 18% γ -linolenic acid.
