“…The lake is located at an elevation of 1086–1109 m and is approximately 29.1 hectares in area with the maximum depth of 6 m [7]. The conductivity of the lake water is 0.867 s m −1 [8], the main cations in this lake are Mg 2+ , Ca 2+ , K + and Na + , and the main anions are SO 4 2- , CO 3 2- , HCO 3 - and Cl - [6]. The pH of the lake water was determined to be pH 8.5–9.0 and the sediment salinity was 22.5 g kg −1 .…”

“…Micro-organisms in lake sediment play an irreplaceable role in the process of carbon cycle, nitrogen cycle, humus decomposition and synthesis [5]. There are many haloalkaline lakes in northwest PR China, which are generally characterized by high pH and salinity [6]. As extreme habitats, haloalkaline lakes contain a large number of microbial and genetic resources, which may have different physiological and biochemical characteristics from those of other habitats.…”

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).
