|摘要:||A bacterial isolate from a sample of oil-contaminated soil was characterized using a polyphasic taxonomic approach. Comparative analysis of the 16S rRNA gene sequence showed that this isolate constituted a distinct phyletic line within the genus Pseudoxanthomonas, displaying >3.7% sequence divergence with respect to recognised Pseudoxanthomonas species. The genus assignment was confirmed by a chemotaxonomic analysis, which revealed the presence of a fatty acid profile characteristic of members of the genus Pseudoxanthomonas (straight-chain saturated, unsaturated and branched-chain fatty acids of the iso/anteiso type and 3-hydroxylated fatty acids) and the presence of a ubiquinone with eight isoprene units (Q-8) as the predominant respiratory quinone. The novel isolate was distinguishable from other members of the genus Pseudoxanthomonas on the basis of a combination of phenotypic properties. The genotypic and phenotypic data show that the strain represents a novel species of the genus Pseudoxanthomonas, for which the name Pseudoxanthomonas spadix sp. nov. is proposed. The type strain is IMMIB AFH-5(T) (=DSM 18855(T)= CCUG 53828(T)).|
