Distribution of two triamines, spermidine and homospermidine, and an aromatic amine, 2-phenylethylamine, within the phylum Bacteroidetes.
Cellular polyamines of the newly additional 19 species belonging to the class Bacteroides of the phylum Bacteroidetes were analyzed by HPLC to display polyamine distribution as a chemotaxonomic marker within the total 41 species. Three profiles, the presence of spermidine, the presence of homospermidine and the absence of both triamines, corresponded to their phylogenetical positions within the four families of the class. The occurrence of an aromatic amine, 2-phenylethylamine, extracted into cellular polyamine fraction, was also determined within the 121 species distributed within the phylum. This aromatic amine was found in Cellulophaga lytica, Cytophaga latercula, Tenacibaculum amylolyticum, Tenacibaculum martimum, Tenacibaculum mesophilum and Psychroflexus torquis belonging to the family Flavobacteriaceae of the class Flavobacteria, and Flexibacter flexilis and Microscilla marina belonging to the family Flexibacteraceae of the class Sphingobacteria.
