Effect of temperature on lipid accumulation in three green microalgae species

The objective of this work was to analyze the growth Scenedesmus acutus, Nannochloropsis oculata and Chlorella vulgaris at different temperatures (25, 30 38°C) in order identify changes lipid content, accumulation neutral lipids fatty acids profile. According results obtained, temperature 30°C does not affect microalgae S. N. C. vulgaris; however, there is a greater amount total acutus 38°C, while for vulgaris, variation lipids. From data obtained from acid profile, we observed palmitic followed by oleic acid. cetane number, any condition evaluated culture can be used biodiesel production. suggest that change during could applied enhance production obtain suitable production.    Key words: oculata, acids, lipids, temperature.
