Phylogenetic analysis based on the 16S rRNA gene sequence revealed that strain CAI-18bT is a member of the genus Rufibacter , showing 97.1 % pairwise similarity to Rufibacter roseus H359T, 96.4 % to Rufibacter tibetensis 1351T, 96.4 % to Rufibacter glacialis MDT1-10-3T and 96.0 % to Rufibacter immobilis MCC P1T. Strain CAI-18bT was rod-shaped, motile, oxidase- and catalase-positive. The predominant fatty acids were iso-C15 : 0 (24.1 %) and iso-C17 : 1 I (22.3 %), the major respiratory quinone was MK-7, and the predominant polar lipids were phosphatidylethanolamine and an unknown aminophospholipid. The G+C content of the genomic DNA of strain CAI-18bT was 50.7 mol%. The novel bacterium can be distinguished from related type strains based on its ability to assimilate N-acetylglucosamine and gentiobiose. On the basis of the phenotypic, chemotaxonomic and molecular data, strain CAI-18bT represents a novel species of the genus Rufibacter, for which the name Rufibacter quisquiliarum sp. nov. is proposed. The type strain is CAI-18bT (=DSM 29854T=NCAIM B.02614T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.001488
