Conversion of 18-carbon Fatty Acids to Long Chain Polyunsaturated Fatty Acids in Some Thraustochytrids

Four strains that produce docosahexaenoic acid (DHA), two Schizochytriums (SR21/N1-27) and two Thraustochytriums (F3-1/W20), were cultured using oleic acid (OA), linoleic acid (LA), and α-linolenic acid (ALA) as carbon sources. These fatty acids in the medium were emulsified with Tween 80 using a ultrasonicator. Though SR21 grew faster than the other strains did, the fatty acid profile of SR21 did not changed throughout the culture period and the DHA content was not affected by the three fatty acids. The fatty acid profiles of the other three strains were affected by the fatty acids, i.e., ALA resulted in a higher DHA content and LA in a lower DHA content. Schizochytrium limacinum SR21 seems to have a different fatty acid syhthetic pathway from the other strains and none of OA, LA and ALA seem to become precursors of DHA in the strain.
