| Abstract: | The effect of exogenously added vitamin E and its synthetic analogues (the hydrophilic form of vitamin E and chromans C13and C1) at a concentration of 9.86 × 10–5M on the growth, lipogenic activity, and the fatty acid composition of the eicosapolyenoic acid–synthesizing oomycete Pythium debaryanumwas studied. The effect was found to depend on the molecular structure of particular compounds. For instance, vitamin E and chroman C13stimulated fungal growth, whereas chroman C1inhibited it. The hydrophilic form of vitamin E enhanced the lipogenic activity of the oomycete. The studied compounds, which possess antioxidant activity, did not exert any noticeable effect on the content of eicosapolyenoic acids and the degree of the unsaturation of fungal lipids. |
