Characterization of Cyanobacterial Hydrocarbon Composition and Distribution of Biosynthetic Pathways

Fatty acid analysis of three cyanobacteria.

Fatty acid analysis from single samples of Anabaena (Nostoc) sp. PCC 7120, M. producens 3L, and Synechococcus sp. PCC 7002. All three strains exhibit similar proportions of hexadecanoic acid and 9-hexadecenoic acid; however, Anabaena (Nostoc) sp. PCC 7120 exhibits a higher proportion of 9-octadecenoic acid and 11-octadecenoic acid and tetradecanoic acid is absent. M. producens 3L contains 11-hexadecenoic acid and no octadecanoic acid. Synechococcus sp. PCC 7002 exhibited a similar composition to Anabaena (Nostoc) sp. PCC 7120 yet has a higher proportion of hexadecanoic acid.
