Phylogenetic analysis based on the 16S rRNA gene sequence revealed that strain JS9T belonged to the genus Proteus in the family Enterobacteriaceae . The highest 16S rRNA gene sequence similarity of strain JS9T was to Proteus vulgaris KCTC 2579T (98.98 %) and the genomic DNA G+C content is 39.0 mol%. DNA–DNA hybridization values were measured and strain JS9T showed <20.8 % genomic relatedness with closely-related members of the genus Proteus . The isolate showed bacterial motility and swarming activity similar to those of pathogenic Proteus mirabilis but distinct from those of other species of the genus Proteus . The isolate grows optimally at 30 °C, at pH 7, and in the presence of 2 % (w/v) NaCl. The main respiratory quinones are ubiquinone Q-8 and Q-10, and the major cellular fatty acids are C16 : 0, summed feature 3 and summed feature 8. The polar lipids comprise phosphatidylglycerol, phosphatidylethanolamine, diphosphatidylglycerol, an unidentified amino lipid, two unidentified amino-phospholipids, and three unidentified lipids. Based on phylogenetic, phenotypic, chemotaxonomic and genotypic analyses, strain JS9T represents a novel species of the genus Proteus , for which the name Proteus cibarius sp. nov. is proposed. The type strain is JS9T (=KACC 18404T=JCM 30699T). An emended description of the genus Proteus is also provided., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.001002
