A novel strain, R2A16-10T, was isolated from greenhouse soil in Yeoju, Korea. The taxonomy of strain R2A16-10T was studied by using polyphasic methods. On the basis of 16S rRNA gene sequence analyses, strain R2A16-10T was found to be phylogenetically related to type strains of Dyella species (96.796.9 %), Frateuria aurantia DSM 6220T (96.5 %), Fulvimonas soli LMG 19981T (96.3 %) and Rhodanobacter species (94.995.7 %). Strain R2A16-10T, which produced yellow-coloured colonies, was Gram-negative, rod-shaped (0.30.4x1.53.5 µm) and motile. The predominant fatty acids were 17 : 1 iso
9c (25.5 %), 15 : 0 iso (18.7 %) and 17 : 0 iso (14.6 %), and the major hydroxy fatty acids were 11 : 0 iso 3-OH (5.0 %), 13 : 0 iso 3-OH (3.4 %) and 17 : 0 iso 3-OH (1.0 %). The major isoprenoid quinone was Q-8. The G+C content of the DNA of the type strain was 63.0 mol%. On the basis of the data from this study, strain R2A16-10T represents a novel species of the genus Dyella, for which the name Dyella yeojuensis sp. nov. is proposed. The type strain is R2A16-10T (=KACC 11405T=DSM 17673T).
Differentiating properties among strain R2A16-10T, members of the genus Dyella and Frateuria aurantia are shown in Supplementary Table S1 available in IJSEM Online.
