Fatty acids profile of spirulina platensis grown under different temperatures and nitrogen concentrations

Colla, Luciane Maria; Bertolin, Telma Elita; Costa, Jorge Alberto Vieira


The influence of culture temperature and the concentration of sodium nitrate (NaNO3) on the gas-chromatographic profile of the fatty acids of the filamentous cyanobacterium Spirulina platensis was evaluated. We found that temperature was the most important factor and that the greatest amount of gamma-linolenic acid (GLA) was obtained at 30 ∞C, the fatty acid profile of the Spirulina cultivated showing that (in order of abundance) palmitic, linolenic and linoleic acids were most prevalent.
