Microalgae due to the ability to accumulate high levels of practically valuable polyunsaturated fatty acids attract attention as a promising raw material for commercial products. The features of the growth processes of cells green protococcal microalgae Oocystis rhomboideus<\/em>, Scenedesmus obliquus<\/em>, Dictyochlorella globosa<\/em> at cultivation in different nutritional mediums were determined. For the rapid accumulation of biomass, combined with high productivity of total lipids fraction yield recommended to use the Fitzgerald medium (Scenodesmus obliquus<\/em>, Oocystis rhomboideus<\/em>) and\/or Bold medium (Dictyochlorella globosa<\/em>). Productivity of lipids decreased in sequence Dictyochlorella globosa<\/em> > Scenodesmus obliquus<\/em> > Oocystis rhomboideus<\/em>. The bulk of fatty acids fraction of the total lipids is unsaturated fatty acids, which accounts for 70 to 83% of the total number of fatty acids. The share of monoenic acids accounts from 18 to 34%, while the share of unsaturated fatty acids - from 44 to 62% of the total number of unsaturated fatty acids fraction. Among the unsaturated acids dominate α-linolenic acid (C18:3n-3), hexadecatetraenic acid (C16:4) and linoleic acid (C18:2).<\/p>\r\n","references":"[1]\tV. A.
