16S ribosomal RNA gene sequence characterization and phylogenetic analysis of a dibenzo-p-dioxin-degrading isolate within the new genus Sphingomonas

Abstract

Partial 16S rRNA gene sequence comparisons have been used to determine the phylogenetic placement of the Elbe River isolate RW1, the first described bacterium capable of complete mineralization of dibenzo‐p‐dioxin. Sequence similarities, cluster analysis and signature positions demonstrate that RW1 groups with other species of Sphingomonas as a distinct, new species of this genus.
