Abstract

A pale pink and strictly aerobic bacterium, designated strain M71, was isolated from the soil of a Euphrates poplar forest in Xingjiang, PR China. Cells of the strain were Gram-reaction-negative, rod-shaped and motile by means of a single polar flagellum. Growth occurred at 10–37 °C (optimum 30 °C), at pH 6.0–9.0 (optimum pH 7.0–8.0) and with 0–2.0 % NaCl (w/v, optimum 0 %). Phylogenetic analysis, based on 16S rRNA gene sequences, indicated that strain M71 belongs to the genus in the family . The 16S rRNA gene sequence of this strain showed 96.2 % sequence similarity with the type strain of 2262. The respiratory quinone was Q-10 and the predominant cellular fatty acids were Cω7 (53.2 %), Cω5 (11.0 %), summed feature 3 (Cω7 and/or Cω6, 10.2 %) and C (8.5 %). The DNA G+C content was 71.2 mol% (HPLC). The strain contained phosphatidylcholine and phosphatidylethanolamine as the predominant polar lipids. On the basis of the phenotypic, chemotaxonomic and phylogenetic data, strain M71 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is M71 ( = CCTCC AB 209291 = CIP 110127).
