Fatty Acid Composition of Planktonic Species of Anabaena (Cyanobacteria) with Coiled Trichomes Exhibited a Significant Taxonomic Value

Twenty-six axenic strains of planktonic Anabaena with coiled trichomes belonging to 13 species were investigated by analyzing the pattern and content of their fatty acid composition, and by comparing their fatty acid composition with their morphological properties. In general, the planktonic Anabaena with coiled trichomes contained 14:0, 16:0, 16:1(cis-), 18:0, 18:1, 18:2, and 18:3(α) as their major fatty acid component, and were classified as Type 2 according to the Kenyon-Murata System. The Type 2 was further divided into two subtypes: Type 2A with 16:2 and 16:3, and Type 2B without 16:2 and 16:3. Among these Anabaena strains with coiled form, A. oumiana (NIES-73 and Ana Kas1) and A. eucompacta (Ana Chiba) contained Type 2B fatty acid composition, and other strains contained Type 2A. Among the strains with the latter type, A. circinalis (Ana Da) and A. curva (Ana Ao) had low levels of 18:3(α). Most Anabaena strains with coiled trichomes showed a strong correlation between morphological characteristics and fatty acid composition.
