We determined the effects of cultivation conditions (nitrogen source, salinity, light intensity, temperature) on the composition of polyunsaturated fatty acids (PUFAs) and the production of eicosapentaenoic acid (EPA) in the laboratory cultured microalga, Trachydiscus minutus. The highest EPA productivity of about 30 mg L−1day−1 was found in microalgae grown at higher light intensities (up to 1,070 μmol photons m−2 s−1), at 28 °C. So, for overproduction of EPA in this species, we propose that outdoor cultivation be used under conditions of a temperate climatic zone in summer, using urea as a nitrogen source.
