abstract= A Gram-negative, strictly aerobic, rod-shaped bacterium, designated strain BD-c54T, was isolated from BTEX (benzene, toluene, ethylbenzene and xylenes)-contaminated soil in Sacheon, Korea. Growth of strain BD-c54T was observed at 15–35 °C (optimum 25–30 °C) and pH 6.0–9.5 (optimum pH 7.0–8.0). The predominant fatty acids were iso-C15 : 0, iso-C17 : 1 ω9c, iso-C11 : 0 3-OH, iso-C16 : 0, iso-C11 : 0 and iso-C17 : 0. The strain contained large amounts of phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol and a small amount of an unknown amino-group-containing polar lipid as polar lipids. The major quinone was ubiquinone-8 (Q-8) and the G+C content of the genomic DNA was 67.5 mol%. A phylogenetic analysis based on 16S rRNA gene sequences showed that strain BD-c54T formed a tight phylogenetic lineage with Pseudoxanthomonas yeongjuensis GR12-1T within the genus Pseudoxanthomonas and was most closely related to P. yeongjuensis GR12-1T and [Stenotrophomonas] dokdonensis DS-16T, with 98.3 and 96.6 % 16S rRNA gene sequence similarity, respectively. The DNA–DNA relatedness between strain BD-c54T and P. yeongjuensis GR12-1T was 24.5 %. On the basis of chemotaxonomic data and molecular properties, strain BD-c54T represents a novel species within the genus Pseudoxanthomonas, for which the name Pseudoxanthomonas sacheonensis sp. nov. is proposed. The type strain is BD-c54T (=KCTC 22080T =DSM 19373T). In addition, the transfer of Stenotrophomonas dokdonensis to Pseudoxanthomonas as Pseudoxanthomonas dokdonensis comb. nov. and an emended description of the genus Pseudoxanthomonas are proposed.,
