Polyamine distribution patterns serve as a phenotypic marker in the chemotaxonomy of the Proteobacteria

摘要: Polyamines of various genera the class Proteobacteria were analyzed by high-performance liquid chromatography to determine if they can serve as taxonomic markers. The major polyamine Zymomonas was homospermidine, whereas Acetobacter–Gluconobacter complex contained spermidine, suggesting presence two different distribution patterns in alpha subclass. Both homospermidine-dominant type and spermidine-dominant found heterogeneous Sphingomonas species. Typical species belonging gamma subclass have their own unique pattern Xanthomonas (spermidine), Azomonas (putrescine), Frateuria Alteromonas (putrescine–spermidine or spermidine), Shewanella Marinomonas Halomonas Deleya (spermidine). Cadaverine sporadically distributed some these genera. Some strains classified into Rhizobacter, Zoogloea, Azomonas, c...
