A Gram-stain-negative, strictly aerobic, non-motile, orange-coloured bacterium, designated YR1-1, was isolated from a soil sample collected from the Yellow River Delta wetlands (PR China). Growth was observed at a salinity of 1.0-15.0 % NaCl, 4-45 °C and pH 6.0-9.0. The results of phylogenetic analysis based on the 16S rRNA gene sequences indicated that YR1-1 represented a member of the genus , with the highest sequence similarity to YIM-C238 (97.9 %), followed by (97.1 %) and (96.4 %). The average nucleotide identity and digital DNA-DNA hybridization values between YR1-1 and other closely related type strains of species of the genus were 68.7-86.3% and 17.8-30.9 %. The genome of the strain was 2 899 374 bp in length with 39.8 % DNA G+C content. The predominant fatty acids (>10 %) were iso-C and anteiso-C. The major respiratory quinone was menaquinone-6 (MK-6) and the major polar lipids were phosphatidylethanolamine, phospholipid, diphosphatidylglycerol, two unidentified aminolipids and four unidentified lipids. The combined genotypic and phenotypic data indicate that YR1-1 represents a novel species within the genus , for which the name sp. nov., is proposed. The type strain is YR1-1 (=KCTC 72794=CGMCC 1.17458).
