Abstract

A Gram-stain-negative, short rod-shaped, non-motile, non-spore-forming bacterial strain, designated H7, was isolated from the Gobi desert, Xinjiang Province of China. The temperature, NaCl and pH ranges for growth were 8–40 °C (optimum 30 °C), 0–5 % (w/v) NaCl and pH 6–10 (optimum pH 7), respectively. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain H7 belonged to the genus and showed highest sequence similarity (91 %) to DSM 18850. The genomic DNA G+C content was 44.3 mol%. MK-7 was identified as the predominant respiratory quinone. Strain H7 contained Cω7 and/or Cω6, iso-C and iso-C 3-OH as major fatty acids. These data support the affiliation of strain H7 to the genus while phenotypic data indicated it is a representative strain of a novel species for which the name sp. nov. is proposed. The type strain is H7 ( = ACCC 05757 = KCTC 32293).
