Cells of the novel strain were straight and rod-shaped and were motile by means of monopolar flagella. A phylogenetic analysis based on 16S rRNA gene sequences revealed that strain CL-YJ9T belongs to the genus Marinobacterium and was most closely related to Marinobacterium halophilum mano11T (94.1 % sequence similarity) and to other members of the genus Marinobacterium (92.5–93.7 % sequence similarity). The strain grew with 1–5 % NaCl (optimum, 3 %) and at 5–30 °C (optimum, approx. 25 °C) and pH 6.0–9.0 (optimum, pH 7.0). The predominant cellular fatty acids were summed feature 3 (C16 : 1 ω7c and/or iso-C15 : 0 2-OH, 40.3 %), C18 : 1 ω7c (26.6 %), C16 : 0 (16.6 %) and C10 : 0 3-OH (7.1 %). The major isoprenoid quinone was Q-8. The G+C content of the genomic DNA was 61 mol%. On the basis of the data from this polyphasic study, strain CL-YJ9T belongs to the genus Marinobacterium but is distinguishable from the recognized species. Strain CL-YJ9T therefore represents a novel species, for which the name Marinobacterium rhizophilum sp. nov. is proposed. The type strain is CL-YJ9T (=KCCM 42386T =DSM 18822T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.65176-0
