Polyamine distributions in the Flavobacterium–Cytophaga–Sphingobacterium complex

Author
Homospermidine was found as the major polyamine in one newly described species of Flavobacterium (Findologenes), in three species of Sphingobacterium (SmizutaeSmultivorium, and Sspiritivorum), and in 10 species of Cytophaga (CaquatilisCarvensicolaCheparinaChutchinsoniiCjohnsonae, "Ckeratolytica," ClyticaCmarinoflavaCuliginosa, and "Cxantha"). These bacteria also all contain putrescine and agmatine as minor components. Flavobacterium indologenes and Cjohnsonaecontain an unusual diamine, 2-hydroxyputrescine, as a major polyamine. The polyamine distributions of four other species originally included in Flavobacterium (Facidurans, "Fdormitator," "Ftirrenicum," and Halomonas halmophila), whose taxonomic positions are or were uncertain, were different from the group mentioned above. They either contain spermidine as the major polyamine or lack any polyamine. These results suggest that homospermidine can serve as a chemotaxonomic marker to delineate true members of the FlavobacteriumCytophagaSphingobacteriumcomplex. Key words: polyamine, homospermidine, hydroxyputrescine, FlavobacteriumCytophagaSphingobacterium.
