ABSTRACT
A bacterial strain, designated 17J36-26T, was isolated from the UV-irradiated soil from Jeju Island, South Korea. Cells are Gram negative, strictly aerobic, non-motile, non-spore forming, rod shaped, and catalase and oxidase positive. The major fatty acids of strain 17J36-26T were summed feature 4 (171 iso I/171 anteiso B), summed feature 3 (161 ω6c/161 ω7c), C161 ω5c and iso-C150. The polar lipid profile contained phosphatidylethanolamine, unidentified aminophospholipid, phospholipids and four unidentified lipids. The G+C content of the strain 17J36-26T was 62.6 mol%. The 16S rRNA gene sequence analysis showed that strain 17J36-26T was phylogenetically related to Hymenobacter qilianensis DK6-37T and Hymenobacter roseosalivarius AA718T (97.5% and 96.8% sequence similarity, respectively). Strain 17J36-26T showed resistance to UV radiation. Both average nucleotide identity (ANI) and in silico DNA-DNA hybridization (isDDH) values between strains 17J36-26T and type strains of Hymenobacter species were lower than the cut-off (≥ 95-96% for ANI and ≥ 70% for isDDH) to define a bacterial new species. The polyphasic approach using genotypic, phenotypic and chemotaxonomic data showed that strain 17J36-26T could be distinguished from its phylogenetically related species, and thus, the strain representative of a novel species within the genus Hymenobacter, for which the name Hymenobacter radiodurans sp. nov. (type strain 17J36-26T = KCTC 62269T = JCM 33185T) is proposed.
