Dynamics of chemical composition of Ettlia carotinosa Komárek 1989 (Chlorophyceae) under experimental induction of secondary carotenogenesis

Dynamics of chemical composition of Ettlia carotinosa Komarek 1989 (Chlorophyceae) under experimental induction of secondary carotenogenesis. E. S. Chelebieva, G. S. Minyuk, I. V. Drobetskaya, I. N. Chubchikova. For the first time, experimental data, characterizing the fractional composition of secondary carotenoids and content of the main components of dry matter (protein, carbohydrates and lipids) were shown in the cells of green microalgae Ettlia carotinosa Komarek 1989 (Chlorophyceae), which was grown in laboratory by the method of two-stage batch culture. In the fractional composition of the secondary carotenoids 11 fractions were identified, but the dynamics of their total content was determined mainly by astaxanthin monoesters (48%-55 % of the total). A characteristic feature of the species is the presence of adonirubin significant amount (10%-12 % of the total).
