abstract= A novel Gram-negative, non-spore-forming, rod-shaped strain, H1T, was isolated from activated sludge by micromanipulation. No close relatives among cultured bacterial isolates were found; phylogenetic analysis based on 16S rRNA gene sequences revealed that strain H1T forms a deep single branch in the family Rhodospirillaceae . Cells of strain H1T were slightly curved to straight rods (1.2–1.4×1.5–1.7 µm) and motile by a single polar flagellum. Strain H1T was able to grow in the presence of 0–4 % NaCl and grew optimally at 37 °C and pH 6.0–7.0. Chemotaxonomic analysis revealed that strain H1T possessed Q-10 as the predominant ubiquinone and C18 : 1ω7c, C16 : 0 and C19 : 0 cyclo ω8c as the major fatty acids. The DNA G+C content of strain H1T was 65.1 mol%. Comparative analysis of 16S rRNA gene sequences, and phenotypic and chemotaxonomic data, indicate that strain H1T should represent a novel genus and species of the family Rhodospirillaceae . The name Taonella mepensis gen. nov., sp. nov. is proposed. The type strain of Taonella mepensis is H1T ( = CICC 10529T  = CCTCC AB 2012861T  = KACC 16940T).,
