Cells of strain LM22T were slightly curved to straight rods (0.3–0.5×0.6–1.0 μm) and motile by a single polar flagellum. Strain LM22T was negative for oxidase and catalase activities and phototrophic growth. An internal membrane system and bacteriochlorophyll a were absent. Growth occurred at 20–40 °C (optimum 30–35 °C) and pH 6.0–10.0 (optimum pH 7.0–7.5). Strain LM22T did not require NaCl for growth and tolerated up to 2.0 % NaCl (optimum 0.5 %). The major ubiquinone was Q-10. The major fatty acids (>10 % of the total) were C18 : 1 ω7c (32.9 %), C19 : 0 cyclo ω8c (18.7 %), C16 : 0 (12.1 %) and C16 : 0 2-OH (10.5 %). Phylogenetic analysis of 16S rRNA gene sequences showed that Inquilinus limosus AU0476T was the closest relative (90.4 % 16S rRNA gene sequence similarity). The DNA G+C content was 65.6 mol%. On basis of phenotypic, chemotaxonomic and phylogenetic data, strain LM22T was considered to represent a novel genus and species of the family Rhodospirillaceae, for which the name Dongia mobilis gen. nov., sp. nov. is proposed. The type strain of Dongia mobilis is LM22T (=CGMCC 1.7660T =JCM 15798T).", }
