Abstract

A novel strain, R2A16-10, was isolated from greenhouse soil in Yeoju, Korea. The taxonomy of strain R2A16-10 was studied by using polyphasic methods. On the basis of 16S rRNA gene sequence analyses, strain R2A16-10 was found to be phylogenetically related to type strains of species (96.7–96.9 %), DSM 6220 (96.5 %), LMG 19981 (96.3 %) and species (94.9–95.7 %). Strain R2A16-10, which produced yellow-coloured colonies, was Gram-negative, rod-shaped (0.3–0.4×1.5–3.5 μm) and motile. The predominant fatty acids were 17 : 1 iso 9 (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 R2A16-10 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is R2A16-10 (=KACC 11405=DSM 17673).
