Fatty Acid Composition of Algae from Habitats with Varying Amounts of Illumination

Fatty Acid Composition of Algae from Habitats with Varying Amounts of Illumination The fatty acid (FA) composition of algae Ulva fenestrata (Chlorophyta), Costaria costata (Phaeophyta), and Grateloupia turuturu (Rhodophyta) differed in their illumination habitats (shaded grotto and bright light). It was found that the light intensity affect the lipid content and fatty acid (FA) ratios in the algae. In the shaded places, the content of polyunsaturated FAs of the (n-3) series in U. fenestrate and of the (n-3) and (n-6) series, except 18 : 2, in C. costata are higher than at bright light, whereas in G. turuturu, the content of 20 : 5n-3 acids in that instance was lower. The lipid content was 2.5–3.6 times higher in the algae at low light intensity. The content variation of algal lipid components apparently was related to adaptive response of these plants to illumination condition. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Marine Biology Springer Journals
