The growth and development of algae are closely interrelated with external<br>factors, under the influence of which the structural, functional and biochemical characteristics of the cell change.<br>Selection of new highly active microalgae-producers of essential compounds in the natural conditions would expand<br>the area of their practical application. The present work shows a comparative study of the amount of vitamins —<br>provitamin A, vitamin C, vitamin E in the ten types and strains of green and Euglena microalgae, isolated from the<br>local flora that grown in semi-industrial terms and under the open atmospheric conditions: Chlorella pyrenoidosa<br>ChickYA-1-1; Scenedesmus obliquus YA-2-6; Ankistrodesmus angustus YA-3-1; Ankistrodesmus braunii;<br>Chlamydomonas reinhardii YA-5-16; Chlamydomonas reinhardii 449; Euglena gracillis YA-4-17; Euglena YA-4-19;<br>Dunaliella salina; Dunaliella minuta UA-5-10. It is shown that the vitamins content depends on the type of algae<br>strain and the seasons, the duration of cultivation and the type of mixing. The developed biomass with a high content<br>of vitamins allow to increase the biotechnological potential of microalgae that will provide an opportunity for the<br>problems solving related to the provision of various sectors of the national economics by algae-rich raw materials:<br>animal husbandry, poultry farming, fish farming, as well as food and pharmaceutical industries.</p> ER -
