Abstract

A bacteria strain, designated CFH 90008, was isolated from a salt lake sediment sample collected from Yuncheng city, Shanxi Province, PR China. Strain CFH 90008 was Gram-stain-negative, strictly aerobic, motile with lateral flagella and rod-shaped. Colonies were yellow, circular and smooth. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain CFH 90008 belonged to the genus , showing highest sequence similarity to DQD2-30 (98.6 %), LCB169 (98.5 %), FB2 (98.1 %) and AIR-2 (98.0 %). Good growth was observed at 10–50 °C, pH 6.0–9.0 and with NaCl concentration from 1.0 to 12.0 % (w/v). The predominant quinone was Q9. The major fatty acid (>10 %) was C ω7, C and C ω7. The genome of strain CFH 90008 was 4.36 Mbp with a genomic DNA G+C content of 66.7 mol%. Based on low average nucleotide identity and DNA–DNAhybridization results, chemotaxonomic characteristics, and differential physiological properties, strain CFH 90008 could not be classified into any recognized species of the genus . Therefore, a new species, for which the name sp. nov. is proposed. The type strain is CFH 90008 (=DSM 103220=KCTC 52281).
