A Gram-negative, strictly aerobic, non-spore-forming bacterium, motile by means of single polar flagellum and rod-shaped, designated strain GR12-1T, was isolated from soil of a ginseng field in Yeongju region, Korea. Phylogenetic analysis based on 16S rRNA gene sequences indicated that this strain is related to members of the genus Pseudoxanthomonas, showing sequence similarity values ranged from 92.3 to 96.2 %. This organism grew at 533 °C, with optimum growth at 28 °C. Strain GR12-1T grew optimally in the presence of 02 % NaCl. The whole-cell fatty acid profile included iso-C15 : 0, iso-C17 : 1
9c, iso-C16 : 0, iso-C11 : 0 3-OH and iso-C17 : 0 as major components. The only isoprenoid quinone was ubiquinone 8 (Q-8). The DNA G+C content was 63.4 mol%. On the basis of phenotypic, genetic and phylogenetic data, strain GR12-1T should be classified as a member of a novel species of the genus Pseudoxanthomonas, for which the name Pseudoxanthomonas yeongjuensis sp. nov. is proposed, with strain GR12-1T (=KACC 11580T=DSM 18204T) as the type strain.
Details of the fatty acid composition of strain GR12-1T and related strains are available as supplementary material in IJSEM Online.
