The isolate grew at 10–37 °C (optimal 25 °C), pH 6–8 (optimal pH 7) and in the presence of 0–1 % (w/v) NaCl. The results of comparative 16S rRNA gene sequence analysis indicated that strain 15J8-5T represented a member of the family Cytophagaceae , phylum Bacteroidetes and was most closely related to Spirosoma knui 15J8-12T (93.1 % similarity), Spirosoma spitsbergense SPM-9T (93.1 %) and Spirosoma endophyticum EX36T (93.1 %). The G+C content of the genomic DNA of the novel strain was 48.0 mol%. The isolate contained menaquinone MK-7 as the predominant respiratory quinone, phosphatidylethanolamine as the major polar lipid, and summed feature 3 (C16 : 1 ω7c/C16 : 1 ω6c; 32.8 %), C16 : 1 ω5c (24.8 %) and C16 : 0 (11.7 %) as the major fatty acids, which supported the affiliation of strain 15J8-5T to the genus Spirosoma . The results of physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain 15J8-5T from members of the genus Spirosoma . Based on its phenotypic properties and phylogenetic distinctiveness, strain 15J8-5T represents a novel species of the genus Spirosoma , for which the name Spirosoma koreense sp. nov. is proposed. The type strain is 15J8-5T (=KCTC 52027T=JCM 31992T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.002440
