“…avenae and Acidovorax avenae subsp. cattleyae had the same chemotaxonomic characteristics and could be distinguished clearly from the genus Pseudomonas sensu strict0 (P. jluorescens rRNA branch [ll]), Burkholderia species, Comamonas species, and Hydrogenophaga species on the basis of phenotypic characteristics (10,17,28,35,38,44), ubiquinone systems, DNA base compositions, DNA-DNA homology data, and rRNA-DNA hybridization data (9,11,52,53) (Table 9). Minimal characteristics for differentiating the genera Burkholderia, Acidovorax, Comamonas, Hydrogenophaga, and Pseudomonas are shown in Table 9.…”

The phylogenetic relationships among members of the family Comamonadaceae and several unclassified strains were studied by direct sequencing of their PCR-amplified 165 rRNA genes. Based on the I65 rRNA gene sequence analysis, members of the family formed a coherent group. The closest relatives are species of the Rubrivivax sub-group: Leptothrix discophora, ldeonella dechloratans and Rubrivivax gelatinosus. The genus Hydrogenophaga formed two subclusters, as did the species of Acidovorax, whereas the five species of the genus Vlquaspirillum] were polyphyletic. Comamonas acidovorans was phylogenetically distant from the type species of Comamonas, Comamonas terrigena. On the basis of this work and previous studies, Comamonas acidovorans is removed from the genus Comamonas and renamed as Delftia acidovorans gen. nov., comb. nov. Descriptions of the new genus Delftia and of the type species Delftia acidoworans, for which the type strain is ATCC 15668T, are presented.

“…The present paper is an extension of our previous phylogenetic studies on Pseudomonas (14,15,17) and deals with the taxonomic locations of saprophytic species and a few clinical named Pseudomonas species from addenda I, 111, and IV in Bergey 's Manual of Determinative Bacteriology, 8th ed. (20), or section V in Bergey's Manual of Systematic Bacteriology (41) or both in our rRNA framework (Fig.…”

The deoxyribonucleic acid (DNA):ribosomal ribonucleic acid (rRNA) hybridization technique was used to reveal the relationships and taxonomic positions of an additional 83 strains belonging to 43 saprophytic or pathogenic Pseudomonus species and 29 named and unnamed Pseudomonus-like strains. The DNA:rRNA hybrids were characterized by the following two parameters: (i) the temperature at which one-half of the hybrid was eluted and (ii) the percentage of rRNA binding (the amount of rRNA bound per 100 pg of filter-fixed DNA). We also used, for a limited number of strains, numerical analysis of carbon assimilation tests to delineate the finer taxonomic relationships of organisms. Of the 83 strains examined, 78 could be definitely assigned either to an rRNA branch or to an rRNA superfamily within the Proteobucteriu. Only 25 of our strains belong in the genus Pseudomonus sensu strict0 (our PseudomonusJluorescens rRNA branch). In general, about two-thirds of the named Pseudomonas species have been misclassified and are distributed over at least seven genera all through the Proteobacteriu. These organisms need to be reclassified and generically renamed according to their phylogenetic rglationships. However, more detailed phenotypic and genotypic studies are necessary before definite nomenclatural proposals can be made. A comprehensive list of the phylogenetic affiliations of the Pseudomonus species is included.From the original creation of Pseudomonas Migula 1894 until now, this genus has been a dumping ground for incompletely described, aerobic, polarly flagellated, gram-negat h e , rodlike bacteria. In the past and even today organisms isolated from a heterogeneous variety of ecological niches were and still are classified without sufficient grounds as new Pseudomonas species. One of the reasons for this situation is the incomplete generic definition.In the United States, the Berkeley group has reported in several papers (42,43,48) on the taxonomy of the genus Pseudomonas. The several hundred strains included in the important study of these workers involved only a relatively small number of species. Their new generic definition and subdivision of Pseudomonas was reflected in Bergey 's Manual of Determinative Bacteriology, 8th ed. (20). In an important reduction in the number of Pseudomonas species, more than 90% of the clinical, phytopathological, and saprophytic pseudomonads were relegated to four addenda to the genus Pseudomonas and were thus only marginally retained in this genus (20). Most of these organisms have no clear taxonomic status because their names were not retained on the Approved Lists of Bacterial Names (38, 46) nor were they on Validation Lists 17 to 23 (24-30). In Bergey's Manual of Systematic Bacteriology , Palleroni (41) listed 62 of these species in Section V of the genus Pseudomonas, although their natural relationships with other taxa are still largely unknown.We have shown in the past (11-15, 21, 45, 51, 54, 55) that the deoxyribonucleic acid (DNA):ribosomal ribonucleic acid (rRNA) hybridization...
