A red-pigmented, Gram-reaction-negative, aerobic, non-motile and rod-shaped bacterium, designated NY03-3-30(T), was isolated from a soil sample collected from Inexpressible Island, Northern Victoria Land of the Antarctic Ross Orogen, and subjected to a polyphasic taxonomic study. Growth occurred at 4-28 degrees C (optimum 20 degrees C) and at pH 6.0-9.0 (optimum pH 7.0). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain NY03-3-30(T) belonged to the genus Hymenobacter in the family Cytophagaceae. 16S rRNA gene sequence similarities between strain NY03-3-30(T) and the type strains of Hymenobacter species with validly published names ranged from 92.7 to 96.2 %. Strain NY03-3-30(T) contained summed feature 3 (C-16 (:) (1)omega 7c and/or C-16 (:) (1)omega 6c), iso-C-15 : 0, C-16 : (0), C-16 : 1 omega 5c, anteiso-C-15 : 0 and summed feature 4 (iso-C-17 : 1-I and/or anteiso-C-17 : 1-B) as major cellular fatty acids, MK-7 as the respiratory quinone and phosphatidylethanolamine as the main polar lipid. The DNA G+C content of strain NY03-3-30(T) was 59.4 mol%. On the basis of phylogenetic, physiological and chemotaxonomic data, strain NY03-3-30(T) is considered to represent a novel species of genus Hymenobacter, for which the name Hymenobacter rubripertinctus sp. nov. is proposed. The type strain is NY03-3-30(T) (=CCTCC AB 2017095(T)=KCTC 62163(T)).
