Algologically pure culture of microalgae Botryococcus braunii was obtained from Alakol Bay of Balkhash Lake.The ability of the selected cultures to synthesize liquid hydrocarbons and fatty acids was revealed.The composition of the lipid compound of investigated microalgae depending on the composition of natural medium was established.Hydrocarbon composition of obtained biomasswas identified, presented mainly by n-alkanes C21-C38, which constitute 41-62 % of their total number.Fatty acid composition of intracellular and extracellular lipids is represented by saturated, monounsaturated and diene fatty acids of the C12-C24 composition in the ratio of 32:18:38, respectively, indicating the potential for using of this microalgae as raw material forbiodiesel.
