Strain THG-DD7T grew optimally at 25–30 °C, at pH 7.0–7.5 and in the presence of 0.5 % (w/v) NaCl. According to the results of 16S rRNA gene sequence comparisons, strain THG-DD7T was most closely related to Rhodanobacter umsongensis GR24-2T (98.2 %), Rhodanobacter panaciterrae LnR5-47T (98.0 %), Rhodanobacter soli DCY45T (97.9 %), Rhodanobacter terrae GP18-1T (97.9 %) and Dyella ginsengisoli Gsoil 3046T (97.7 %). The DNA G+C content was 65.2 mol%. In DNA–DNA hybridization, the DNA relatedness levels between strain THG-DD7T and its closest phylogenetically neighbours were below 40.0 %. The predominant isoprenoid quinone was ubiquinone Q-8. The major polar lipids were diphosphatidylglycerol, phosphtidylethanolamine, phosphatidyl-N-methylethanolamine and phosphatidylglycerol. The major fatty acids were iso-C15 : 0, iso-C16 : 0, iso-C17 : 0, anteiso-C15 : 0 and iso-C17 : 1ω9c and/or C16 : 0 10-methyl (summed feature 9). These data supported the affiliation of strain THG-DD7T to the genus Rhodanobacter . The results of physiological and biochemical tests enabled strain THG-DD7T to be differentiated genotypically and phenotypically from the species of the genus Rhodanobacter with validly published names. Therefore, the novel isolate represents a novel species, for which the name Rhodanobacter koreensis sp. nov. is proposed. The type strain is THG-DD7T ( = KACC 17650T = JCM 19614T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.000077
