“…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.…”

The 16s rRNA sequences of Chryseomonas Zuteola, the type species of the genus Chryseomonas, and Flavimonas oryzihabitans, the type species of the genus Flavimonas, were determined. These sequences were compared with the sequences of 27 representative strains of the genus Pseudomonus. C. Zuteola and F. oryzihabitans were located in the cluster that contains Pseudomonas aemginosa, the type species of genus Pseudomonas Migula 1894, and the levels of 16s rRNA sequence homology between P. aemginosa and the other two species were more than 93.9%. All of the strains of the genus Pseudomonas sensu stricto whose sequences have been determined were included in the P. aemginosa cluster. These results suggested that Chryseomonas, Flavimonas, and Pseudomonas are synonymous, and we concluded that Chryseomonas and Flavimonas are junior subjective synonyms of Pseudomonas.

“…Many members of the Sphingomonas genera possess unique abilities in degrading refractory organic pollutants [26] and antagonizing phytopathogenic fungi [3]. Some members of the genus are involved in metal corrosion [1] and some are considered as potential opportunistic human pathogens [28].…”

“…The genus Sphingomonas was proposed by Yabuuchi et al [28] to describe bacterial strains isolated from human clinical specimens and hospital environments. It was later found that this group of bacteria could also be isolated from natural sources, such as soil, rhizosphere, sediment, freshwater and marine environments [26].…”

Sphingomonas spp possess unique abilities to degrade refractory contaminants and are found ubiquitously in the environment. We developed Sphingomonas genus-specific PCR primers (SPf-190 and SPr1-852) which showed specific amplification of a 627-bp 16S rDNA fragment from Sphingomonas spp. A PCR assay using these Sphingomonas specific primers was developed to detect Sphingomonas aromaticivorans B0695R in three texturally distinct soil types, showing detection limits between 1.3-2.2 × 10 3 CFU g −1 dry soil. A sphingolipid extraction protocol was also developed to monitor Sphingomonas populations in soil quantitatively. The detection limit of the assay was 20 pmol g −1 dry soil, equivalent to about 3 × 10 5 cells g −1 dry soil. Survival of S. aromaticivorans B0695R was monitored in the three different soils by antibiotic selective plate counting, PCR and sphingolipid analysis. All three approaches showed that the B0695R cells persisted in the low biomass Sequatchie sub-soil at about 3-5 × 10 7 cells g −1 dry soil. In comparison to the plate counting assay, both the PCR and sphingolipid analysis detected a significantly higher level of B0695R cells in the clay soil and Sequatchie top-soil, indicating the possibility of the presence of viable but non-culturable B0695R cells in the soils. The combination of PCR and sphingolipid analysis may provide a more realistic estimation of Sphingomonas population in the environment.

Phylogenetic Analysis of Bacterial Populations Found in Groundwater and an Acidic Stream Draining from an Abandoned Coal Mine.

A phylogenetic analysis of heterotrophic bacterial populations inhabiting streams and groundwater contaminated by acid mine drainage (AMD) was conducted. The samples were collected from sites around an inactive underground Dae-Sung coal mine at Keumsan, Korea. The investigation showed pigment-forming bacteria to be the major strains inhabiting the pollutant, accounting for up to approximately 50% of all isolates. Twenty-six pigment-forming bacteria were isolated and their taxonomic characteristics determined by phenotypic, chemotaxonomic and phylogenetic analyses. Based on a phylogenetic analysis using 16S ribosomal RNA gene nucleotide sequences, these isolates were found to fall within four major phylogenetic groups: a, b, and g subdivisions of Proteobacteria; and low-G+C gram-positive bacteria. The a-Proteobacteria were further separated into a-1, a-2 and a-4 subclasses. Many isolates from the polluted stream (site P5) and groundwater (site G) were identified as Sphingomonas of the Proteobacteria a-4 subclass. Because strains P5-21 and P5-11 appeared to be novel species within the genus Sphingomonas, the discussion was focused on their taxonomy as well as abundance in the polluted regions.
