| Abstract: | Abstract Polyamines were analyzed in 12 of N2-fixing aerobic eubacteria and other eubacteria, cyanobacteria, algae and ferns. sym -Homospermidine (homospermidine) was found to be widely distributed as a major polyamine in various N2-fixing eubacteria which belong to Azospirillum, Agromonas, Beijerinckia, Bradyrhizobium, Rhizobium and Xathnbacter . 3 species of Azotobater contained spermidine but not homospermidine, though they are N2-fixing eubactera. Homospermidine is also distributed in some eubacteria, i.e., the photosynthetic Rhodopseudomanas rutila and the sulfur-oxidizing Thiobacillus denitrificans , a cyanobacterium, Synechococcus sp., and in the cyanobacterium-symbiotic ferns, Azolla imbircatta and Azolla japonica . |
