Strain THG-A18T grew optimally at 25–30 °C, at pH 7.0–8.0 and in the absence of NaCl. Strain THG-A18T displayed β-glucosidase activity, which enabled it to convert ginsenoside Rb1 to Rd. According to 16S rRNA gene sequence analysis, strain THG-A18T was shown to belong to the genus Chryseobacterium . The closest phylogenetic neighbours were Chryseobacterium ginsenosidimutans THG 15T (97.9 % 16S rRNA gene sequence similariity), C. defluvii B2T (97.7 %), C. daeguense K105T (97.6 %), C. taiwanense BCRC 17412T (97.5 %), C. indoltheticum LMG 4025T (97.4 %), C. gregarium P 461/12T (97.4 %) and C. lathyri RBA2-6T (97.3 %), but DNA–DNA relatedness values between these strains and strain THG-A18T were below 41.9 %. The G+C content of the genomic DNA was 36.4 mol%. The major respiratory quinone (MK-6) and fatty acids [iso-C15 : 0, iso-C17 : 0 3-OH, summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c) and summed feature 9 (comprising iso-C17 : 1ω9c and/or 10-methyl C16 : 0)] supported the affiliation of strain THG-A18T with the genus Chryseobacterium . The polar lipids of strain THG-A18T were phosphatidylethanolamine, four unidentified aminolipids and seven unidentified lipids. A number of physiological and biochemical tests allowed phenotypic differentiation of strain THG-A18T from recognized species of the genus Chryseobacterium . The name Chryseobacterium gwangjuense sp. nov. is proposed, with THG-A18T ( = KACC 16227T = LMG 26579T) as the type strain., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.052118-0
