Abstract
The lipids profile of Chlorella vulgaris grown on an organic medium and inorganic medium were examined.
1) The neutral lipid on the organic medium was 2.8 g/100 g and inorganic medium was 1.88 g/100 g of the total dry weight, which composed of 80% waxesters and 20% triacylglycerols on both medium.
2) The phospholipid on the organic medium was 8.6 g/100 g and on the inorganic medium was 6.2 g/100 g of the total dry weight, those composition (PG, PC, PE, PI) on the both medium were similar but those distribution of the fatty acid were different.
3) The glycolipid were contained on the both medium about 5.7 g/100 g of the total dry weight, those composition (MGDG, DGDG, SQDG) and fatty acid composition of each glycolipid on the both medium were different.
4) Both hexadecatetraenoic acid (C16 : 4) and octadecatetraenoic acid (C18 : 4) were observed in the glycolipid and phospholipids except PG which was absent, while triacylglycerols were not present.
5) Trans-hexadecenoic acid was present only in the PG, which contained 1.6% on organic medium and 2.3% on inorganic medium.
