Abstract:
The taxonomic status of a yellow-coloured bacterial isolate from an oil-contaminated soil sample was determined using a polyphasic taxonomic approach. Comparative analysis of 16S rRNA gene sequences showed that the novel isolate formed a distinct phyletic line within the genus Sphingobium. The generic assignment was confirmed by chemotaxonomic data, which revealed: a fatty acid profile that is characteristic of the genus Sphingobium consisting of straight-chain saturated and unsaturated as well as 2-OH fatty acids; a ubiquinone with ten isoprene units (Q-10) as the predominant respiratory quinone; a polar lipid pattern consisting of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylmonomethylethanolamine, phosphatidylcholine and sphingoglycolipid, and spermidine as the major polyamine component. Genotypic and phenotypic data show that the new isolate merits classification as a representative of a novel species of the genus Sphingobium, for which the name Sphingobium olei sp. nov. is proposed. The type strain is IMMIB HF-1T (=DSM 18999T=CCUG 54329T).
