ABSTRACT
A Gram-stain-negative, strictly aerobic, non-motile, rod-shaped bacterium, designated CWB-1T, was isolated from a haloalkaline lake sediment sample collected from the bottom of Chaiwopu Lake, Urumchi, Xinjiang Province, PR China. Strain CWB-1T grew at 4-40 °C (optimum, 30-35 °C), pH 6.5-9.0 (optimum, pH 6.5-7.0) and with 0.5-5.5 % (w/v) NaCl (optimum, 2.5-3.0 %). Phylogenetic analyses based on the 16S rRNA gene sequence and the whole genome sequence both revealed that strain CWB-1T belonged to the family Flavobacteriaceae. The strain had the highest similarity of the 16S rRNA gene sequence to Psychroserpens jangbogonensis PAMC 27130T (92.8 %). The genome of strain CWB-1T was 3 548 011 bp long with 36.3 % DNA G+C content. The predominant fatty acids (>10 %) in the CWB-1T cells were iso-C15  0, iso-C17  0 3-OH and summed feature 1 (iso-C15  1 H/C13  0 3-OH). The major respiratory quinone was menaquinone-6 and the major polar lipids were phosphatidylethanolamine, an unidentified aminolipid and two unidentified lipids. Based on the phylogenetic analyses, as well as the phenotypic characteristics, a novel genus and species of the family Flavobacteriaceae, Paucihalobacter ruber gen. nov., sp. nov., is proposed. The type strain is CWB-1T (=KCTC 72450T=CGMCC 1.17149T).
