[Changes in the amount of fatty acids produced by Melosira dastei culture on synthetic medium].
Some of fatty acids contents of the marine Diatom, Melosira dastei, were characterized. The major constituents of them are palmitic, palmitoleic and eicosapentaenoic acids. Linolenic acid type appeared to be a minor constituent. When that Diatom is cultured on an artificial medium, it might be considered as a potential source of valuable eicosapentaenoic acid. Even when the cells concentration is low, in batch cultures, eicosapentaenoic acid constitutes up to 5% of the dry weight and reaches about 20% of the triglycerids content. This level might be improved.
