A Gram-negative, strictly aerobic, non-spore-forming, rod-shaped, red–pink bacterium, designated strain Dae14T, was isolated from stream sediment collected near Daecheong Dam, South Korea, and its taxonomic position was investigated by using a polyphasic approach. Phylogenetic analysis of 16S rRNA gene sequences showed that strain Dae14T belonged to the genus Hymenobacter. Sequence similarities between strain Dae14T and the type strains of Hymenobacter species with validly published names ranged from 91.3 to 94.3 %. The predominant cellular fatty acids of strain Dae14T were iso-C15 : 0, C16 : 1
5c, summed feature 5 (iso-C17 : 1 I and/or anteiso-C17 : 1 B) and iso-C16 : 0. The DNA G+C content was 62.2 mol%. Results of phylogenetic, chemotaxonomic and phenotypic characterization indicated that strain Dae14T can be distinguished from all known Hymenobacter species and represents a novel species, for which the name Hymenobacter daecheongensis sp. nov. is proposed, with Dae14T (=KCTC 22258T=LMG 24498T) as the type strain.
A table showing cellular fatty acid data for strain Dae14T and related strains is available as supplementary material with the online version of this paper.
