Acidovorax, a New Genus for Pseudomonas facilis, Pseudomonas delafieldii, E. Falsen (EF) Group 13, EF Group 16, and Several Clinical Isolates, with the Species Acidovorax facilis comb. nov., Acidovorax delafieldii comb. nov., and Acidovorax temperans sp. nov.

The Phylogeny of the Genera Chryseomonas, Flavimonas, and Pseudomonas Supports Synonymy of These Three Genera

“…There was a good correlation between rRNA groups I to V and groups 1 to 5 based on cellular fatty acids and quinone systems. In the past two decades Pseudomonas species belonging to rRNA groups I1 to V or fatty acid and quinone groups 2 to 9 have been transferred to other genera (10,13,14,16,17,19,20). At this time, the genus Pseudomonas is restricted to Palleroni rRNA group I, and only the group I strains belong to the genus Pseudomonas sensu stricto.…”

Transfer of Several Phytopathogenic Pseudomonas Species to Acidovorax as Acidovorax avenae subsp. avenae subsp. nov., comb. nov., Acidovorax avenae subsp. citrulli, Acidovorax avenae subsp. cattleyae, and Acidovorax konjaci

“…pg-') and 23s [14C]rRNA from Xylophilus ampelinus NCPPB 2217' (3 x lo3 dpm . pg-l) were available from members of our research group (11,60,61). Each hybrid was characterized by its T,,(,, [T,(,, is the temperature, in degrees Celsius, at which 50% of a DNA-rRNA duplex is denatured].…”

Transfer of Pseudomonas plantarii and Pseudomonas glumae to Burkholderia as Burkholderia spp. and Description of Burkholderia vandii sp. nov.

“…The results of rRNA-DNA hybridization experiments performed with P. avenae and P. cattleyae (9,11,55) demonstrated that these bacteria belong in the Pseudomonas acidovorans rRNA complex in rRNA superfamily I11 (11,28). In 1992, Willems et al (54) proposed the transfer of P. avenue and P. cattleyae to the new genus Acidovorax (53) as Acidovorax avenue subsp. avenue and Acidovorax avenae subsp.…”

“…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.…”
