Abstract：
:Twenty-four axenic strains of planktonic Anabaena with straight trichomes, assigned to 7 species, were investigated by analyzing the pattern and content of their fatty acid composition and comparing their fatty acid composition with their morphological properties. In general, the fatty acids in planktonic Anabaena contained 14:0, 16:0, 16:1(cis-), 18:0, 18:1, 18:2, and 18:3(alpha) as their major components, and were classified as Type 2 according to the Kenyon-Murata system. These strains were further divided into 2 subtypes: 18 strains belonging to Type 2A, which contains 16:2 and 16:3, and 6 strains to Type 2B, which lacks 16:2 and 16:3. Fatty acid compositions of strains of A. solitaria, A. smithii, and A. kisseleviana closely corresponded to morphological properties; however, 10 strains of A. planctonica were divided into 4 clusters, and 3 strains of A. affinis into 2 clusters. These clusters should be taxonomically evaluated based on other aspects such as genetic characteristics.
