Abstract

The marine microalgaePhaeodactylum tricornutum, with a high lipid content constituting 20–60% of its dry weight under controlled growth conditions (1), has recently come into focus as a potentially rich source of dietary marine vegetable oil. In particular, this species has a characteristic high content of eicosapentenoic acid (EPA), which has potential benefits in human nutrition, since it cannot be synthesized in vivo in the human body. Some factors that could alter the biochemical composition ofPhaeodactylum tricornutum in favor of lipid production have been examinated in this study.
