Dyadobacter beijingensis sp nov, isolated from the rhizosphere of turf grasses in China

Strain A54(T) was isolated from rhizospheric soil of turf grasses irrigated with reclaimed water in Taoranting Park, Beijing, China. Phenotypic, chemotaxonomic and polygenetic analyses established the affiliation of the isolate to the genus Dyadobacter. Strain A54(T) possessed 97.7, 94.4 and 94.7 % 16S rRNA gene sequence similarity with respect to the type strains of Dyadobacter fermentans, D. hamtensis and D. crusticola, respectively. Furthermore, DNA-DNA hybridization did not show significant relatedness (< 25 % hybridization) between strain A54(T) and D. fermentans ATCC 700827(T). Therefore, these results indicate that strain A54(T) belongs to a novel species of the genus Dyadobacter, for which the name Dyadobacter beijingensis sp. nov. is proposed. The type strain is strain A54(T) (=CGMCC 1.6375(T)=JCM 14200(T)).
