| Abstract | ||
| This paper analyzed the dry mass output of microalgae from wet biomass in terms of their genus. The amount of dry mass outputs of microalgae was determined as follows: 27.6% in Ankistrodesmus strains, 25.2% in Scenedesmus strains, 23.4% in Botryococcus strains, 26.2% in Chlorella strains and 27.5% in Chlorococcum strains. Protein and fat content of microalgae were observed to differ sharply from each other when grown in Chu-13 nutrient medium. At the same time, it was noted that microalgae of the genus Ankistrodesmus contain 43.2-46.4% protein and 27.4-32.2% fat. In the same nutrient medium, microalgae of the species Scenedesmus retain 48.8-52.8% protein and 27.4-28.6% fat, respectively. Representatives of the species Botryococcus retain relatively less protein (46.2–46.8%) and fat (26.2–26.4%). While representatives of the species Chlorococcum and Chlorella retain high protein (46.4–48.8%) but low-fat synthesis (15.6–18.4%). | ||
