Conteúdo lipídico e composição de ácidos graxos de microalgas expostas aos gases CO2, SO 2 e NO

Radmann, Elisangela Martha; Costa, Jorge Alberto Vieira


The objective of the present work was to verify the lipid content and the fatty acid composition of the microalgae Spirulina sp., Scenedesmus obliquus, Synechococcus nidulans and Chlorella vulgaris cultivated in a medium containing CO2, SO2 and NO. The microalga Scenedesmus obliquus presented the highest lipid content (6.18%). For the other microalgae the lipid content ranged from 4.56 to 5.97%. The major monounsaturated fatty acids content was 66.01% for S. obliquus. The PUFA were obtained in major amount by the microalgae Spirulina sp. (29.37%) and S. nidulans (29.54%). The palmitoleic acid was in larger amount, with 41.02% concentration (Spirulina sp.)
