Screening of fatty acid composition in 150 strains of marine microalgae, cyanobacteria and green algae was carried out, and 20 strains showed relatively high contents of palmitoleic acid. Among them, two cyanobacteria, Phormidium sp. NKBG 041105 and Oscillatoria sp. NKBG 091600, showed an unusually high cis-palmitoleic acid content (54.5% and 54.4% of total fatty acid, respectively). Phormidium sp. NKBG 041105 had the highest cis-palmitoleic acid content per biomass (46.3 mg (g dry cell weight)-1), and cis-palrnitoleic acid composition was found to be constant with varying temperature. These results indicate that this cyanobacterium could be considered as a new source for palmitoleic acid.
