Potential of Lipid Biosynthesis under Heterotrophy in the Marine Diatom .

Despite the theoretical high productivity, microalgae-based oil production is not economically sustainable due to the high cost of photoautotrophic cultures. Heterotrophic growth is a suitable economic alternative to overcoming light dependence and climatic/geographic fluctuations. Here we report data about growth performance, biomass production, and lipid composition of the marine diatom , chosen as a model strain for biodiesel production in heterothrophy.

Comparative Fatty Acid Profiling of Edible Fishes in Kuala Terengganu, Malaysia.

The aim of this study was to compare the relative nutritional benefit of edible Malaysian fishes from the coast of Terengganu in Malaysia, as well as to perform a taxonomical characterization and metal assessment. Discrimination between species was carried out by a morphological and molecular approach by evaluating the total concentrations of metals by ICP-MS analyses and the fatty acids (FA) composition using the GC-MS approach on the fish fillet tissues. The taxonomical studies detected fishes of 11 families and 13 species.

Autotrophic vs. Heterotrophic Cultivation of the Marine Diatom for EPA Production.

Recently, the marketable value of ω-3 fatty acid, particularly eicosapentaenoic acid (EPA), increased considering their health effects for human consumption. Microalgae are considered a valuable and "green" source of EPA alternative to fish oils, but considerable efforts are necessary for their exploitation at an industrial level. Due to the high operation costs of photoautotrophic microalgae cultivation, heterotrophic growth represents a promising economic solution.
