The cells were facultatively anaerobic, Gram-staining-negative, non-motile and rod-shaped. Growth occurred at 4–32 °C (optimum, 25–28 °C), at pH 5.0–9.0 (optimum, pH 6.0–7.0) and with 0–1.0 % (w/v) NaCl (optimum, no NaCl). Flexirubin-type pigments were absent. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain R9-65T belonged to the genus Mucilaginibacter in the family Sphingobacteriaceae . The 16S rRNA gene sequence similarity between strain R9-65T and type strains of related species ranged from 93.4 to 96.6 %. Strain R9-65T contained summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c, 34.3 %) and iso-C15 : 0 (20.3 %) as major cellular fatty acids, MK-7 as the major respiratory quinone, and phosphatidylethanolamine as the main polar lipid. The DNA G+C content of strain R9-65T was 47.2 mol%. On the basis of phylogenetic, physiological and chemotaxonomic data, strain R9-65T is considered to represent a novel species of the genus Mucilaginibacter , for which the name Mucilaginibacter soli sp. nov. is proposed. The type strain is R9-65T ( = CCTCC AB 2010331T = NRRL B-59458T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.033902-0
