Аlgal density 3.5 g.dm-3 of dry weight was achieved in laboratory, and high lipid content (26 % of dry weight) due to the abundance of triacylglycerols was found. The lipids of alga were characterized with about 26 % myristic and 30 % eicosapentaenoic acids. The first lipid is used in cosmetics, the second as a nutrient additive. Sterols were quantified and GC-MS identified, too. Composition of T. minutus was: proteins (43 %), carbohydrates (25 %), and chlorophyll a (0.6 %). The cultivation was successfully run in pilot plant scale (330 dm3, 2 m2, in greenhouse), for the first time ever.
