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 (0.3-0.4x1.5-3.5 mum) and motile. The predominant fatty acids were 17 : 1 iso omega9c (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)).
