英文摘要: | The effect of light intensity, light spectral quality, temperature and salt concentration on the fatty acid composition of Chromera velia was studied . Chromera velia is a unicellular, marine, photosynthetic, eukaryotic alga and a close relative of the apicomplexan parasites. Chromera velia was able to grow at light intensities between 20 and 450 μmol photons m−2 s−1, in the temperature range 17–32 °C and at salinities between 0.2 and 1 M NaCl. The cells responded to variations in the growth regime by modifying fatty acid composition: the ratio of fully saturated palmitic acid (C16:0) and five times unsaturated eicosapentaenoic acid (C20:5n–3) was especially prone to variation. Intermediate fatty acids, namely stearic, linoleic and dihomo-γ-linolenic acids, changed... |
