| Popis: | A novel marine bacterial strain designated JAMH 011Twas isolated from the cold-seep sediment in Sagami Bay, Japan. Cells were Gram-stain-negative, rod-shaped, non-spore-forming, aerobic chemo-organotrophs and motile by means of a single polar flagellum. Growth occurred at temperatures below 31 °C, with the optimum at 25 °C. The major respiratory quinone was Q-10. The predominant fatty acid was C18 : 1ω7c. On the basis of 16S rRNA gene sequence analysis, the isolated strain was closely affiliated with members of the genusShimiain the classAlphaproteobacteria, and the 16S rRNA gene sequence similarity of the novel isolate with the type strain of the closest related species,Shimia haliotisWM35T, was 98.1 %. The DNA G+C content of the novel strain was 57.3 mol%. The hybridization values for DNA–DNA relatedness between strain JAMH 011Tand reference strains belonging to the genusShimiawere less than 9.4 ± 0.7 %. Based on differences in taxonomic characteristics, the isolated strain represents a novel species of the genusShimia,for which the nameShimia sagamensissp. nov. is proposed. The type strain is JAMH 011T( = JCM 30583T = DSM 29734T) |
