Long Chain Fatty Acids (LCFA)

Linoleic Acid (LA)

Arachidonic Acid (ARA)

Eicosapentaenoic acid (EPA)

Docosahexaenoic acid (DHA)

Fish Oil (FO)

Vegetable Oil (VO)

Microbial Oil (MO)

Since Long Chain Fatty Acids (LCFA) as n-6 and n-3 (omega 3) are assimilated only through diet, fish must be fed with omega-3-enriched feed. n-6 LCFA, as Linoleic Acid (LA) and Arachidonic Acid (ARA), are available in several cheap Vegetable Oil, while n-3 LCFA, as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are very rare and available only in Fish Oil. Therefore this project aims to select yeasts and microalgae strains that, in optimized fermentation conditions, will produce MO respectively enriched in linolenic, carotenoids, and EPA/DHA.
