Trachydiscus minutus, a new biotechnological source of eicosapentaenoic acid.
The yellow-green alga Trachydiscus minutus (class Xanthophyta) was cultivated in a standard medium and in media without sulfur and nitrogen. Its yield after a 16-d cultivation reached 13 g dry mass per 1 L medium. The content of oligoenoic ('polyenoic') fatty acid (PUFA), i.e. eicosapentaenoic (EPA), was in excess of 35 % of total fatty acids; the productivity was thus 88 mg/L per d. This result makes the alga a very prospective organism that may serve as a new biotechnological source of single cell oil.
