A mesophilic bacterium, designated strain YIM 31327(T), was isolated from a forest soil sample collected from Yunnan Province, China, and was then investigated using a polyphasic approach. The strain grew optimally at 28-30 degreesC and pH 7(.)2. The cells were Gram-negative, short, rod-shaped, motile and non-spore-forming with flagella. The major ubiquinone was Q-8 and the cellular fatty acids were C-16:0 and C-12:0. The DNA G+C content of strain YIM 31327(T) was 62(.)8 mol%. Phylogenetic analysis revealed that strain YIM 31327(T) was a member of the beta-Proteobacteria, being most closely related to Duganella zoogloeoides, with which it exhibited less than 96 % 16S rRNA gene sequence similarity. On the basis of the phenotypic and genotypic differences between strain YIM 31327(T) and D. zoogloeoides, a novel species, Duganella violaceinigra sp. nov., is proposed, with YIM 31327(T) (=CIP 108077(T)=KCTC 12193(T)) as the type strain.
