Dyella yeojuensis sp nov., isolated from greenhouse soil in Korea

A novel strain, R2A16-10(T), was isolated from greenhouse soil in Yeoju, Korea. The taxonomy of strain R2A16-10(T) was studied by using polyphasic methods. On the basis of 16S rRNA gene sequence analyses, strain R2A16-10(T) was found to be phylogenetically related to type strains of Dyella species (96-7-96-9%), Frateuria aurantia DSM 6220(T) (96-5%), Fulvimonas soli LMG 19981(T) (96-3%) and Rhodanobacter species (94-9-95-7%). Strain R2A16-10(T), which produced yellow-coloured colonies, was Gram-negative, rod-shaped (0-3-0-4 x 1-5-3-5 mu m) and motile. The predominant fatty acids were 17 : 1 iso omega 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 R2A16-10(T) represents a novel species of the genus Dyella, for which the name Dyella yeojuensis sp. nov. is proposed. The type strain is R2A16-10(T) (=KACC 11405(T) = DSM 17673(T)).
