Polyamines of the four families and the five related genera within the gamma subclass of the class Proteobacteria were analyzed by HPLC with the objective of developing a chemotaxonomic system. The production of putrescine, diaminopropane, cadaverine, and agmatine are not exactly correlated to the phylogenetic genospecies within 36 strains of the genus Aeromonas (the family Aeromonadaceae) lacking in triamines. The occurrence of norspermidine was limited but not ubiquitous within the family Vibrionaceae, including 20 strains of Vibrio, Listonella, Photobacterium, and Salinivibrio. Spermidine was not substituted for the absence of norspermidine in the family. Agmatine was detected only in Photobacterium. Salinivibrio and some strains of Vibrio were devoid of polyamines. Vibrio ("Moritella") marinus contained cadaverine. Within the family Pasteurellaceae, Haemophilus contained cadaverine only and Actinobacillus contained no polyamine. Halomonas, Chromohalobacter, and Zymobacter, belonging to the family Halomonadaceae, ubiquitously contained spermidine and sporadically cadaverine and agmatine. Shewanella contained putrescine and cadaverine; Alteromonas macleodii, putrescine, 2-hydroxyputrescine, cadaverine, 2-hydroxyspermidine, and spermidine; Pseudoalteromonas, putrescine, cadaverine, and spermidine; Marinobacter, spermidine; and Marinomonas, putrescine and spermidine. Their polyamine profiles serve as a chemotaxonomic marker within the gamma subclass.
