Abstract

A Gram-negative, rod-shaped, non-motile, strictly aerobic bacterium, strain S3-63, was isolated from desert sand of Xinjiang, China. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain S3-63 had highest similarity to type strains of the genus , i.e. H32 (97.2 % similarity), MSW-14 (95.9 %), KCTC 22735 (95.5 %), JCS350 (95.1 %), KCTC 22736 (95.1 %), SW-109 (95.0 %) and LMG 23789 (93.5 %). Growth occurred at 20–37 °C (optimum 30 °C), at pH 7.0–9.0 (optimum pH 8.0) and in 0–3 % (w/v) NaCl (optimum 1 %). The major respiratory quinone was ubiquinone-10 and the predominant cellular fatty acids were Cω7 (50.8 %), summed feature 3 (Cω7 and/or Cω6; 12.6 %), C (12.3 %), C 2-OH (7.3 %) and Cω6 (4.5 %). The DNA G+C content was 64.6 mol%. Therefore, the phylogenetic, physiological and chemotaxonomic data demonstrated that strain S3-63 represents a novel species of the genus , for which the name sp. nov. is proposed; the type strain is S3-63 ( = CCTCC AB 207166 = CIP 110125). An emended description of the genus is provided.
