Description of Sphingomonas xenophaga sp. nov. for strains BN6T and N,N which degrade xenobiotic aromatic compounds.
The taxonomic position of two bacterial strains, BN6T and N,N, with the ability to degrade xenobiotic aromatic compounds (naphthalenesulfonates or N,N-dimethylaniline) was investigated. The 165 rRNA gene sequence, the G+C content of the DNA (62-63 mol%) and the detection of ubiquinone Q-10, 2-hydroxymyristic acid and the sphingoglycolipid present clearly placed the two strains into the genus Sphingomonas. Both strains are representatives of one species according to the level of DNA relatedness (70.7%). The strains could be separated from all validly described taxa of the genus Sphingomonas, according to the 16S rRNA gene sequence (the highest sequence similarity observed was 96 % to Sphingomonas yanoikuyae), the pattern of the polar lipids and physiological characteristics. Therefore, the new species Sphingomonas xenophaga is proposed to accommodate strains BN6T (= DSM 6383T) and N,N (= DSM 8566).
