摘要：A novel Gram-negative, aerobic, rod-shaped bacterium, RS19(T), was isolated from rose rhizosphere soil. The strain was psychrophilic and showed good growth over a temperature range of 1-37 celcius. Colonies on TSB agar were circular, smooth, mucoid, convex with clear edges and yellow. Phylogenetic analysis based on 16S rRNA gene sequences characterized RS19(T) in the genus Dyadobacter and showed that strain RS19(T) was most closely related to Dyadobacter psychrophilus CGMCC 1.8951(T) (97.4%) and Dyadobacter alkalitolerans CGMCC 1.8973(T) (97.1%). The average nucleotide identity values to the closest related species type strains were less than 84.0%. The DNA G + C content was 43.1 mol%, and the predominant respiratory menaquinone was MK-7. The major fatty acids were summed features 3 (C-16:1 omega 7c and/or C-16:1 omega 6c), iso-C-15:0, C-16:1 omega 5c and iso-C-17:0 3-OH. Based on genotypic, phenotypic and chemotaxonomic data, strain RS19(T) is different from closely related species of the genus Dyadobacter. RS19(T) represents a novel species within the genus Dyadobacter, for which the name Dyadobacter luteus sp. nov. is proposed. The type strain is RS19(T) (= CGMCC 1.13719(T) = ACCC 60381(T) = JCM 32940(T)).
