Hymenobacter soli sp nov., isolated from grass soil

Abstract

A Gram-negative, strictly aerobic, non-spore-forming, rod-shaped, red-pink bacterium, designated strain PB17(T), was isolated from grass soil in the Republic of Korea and its taxonomic position was investigated by means of a polyphasic approach. Phylogenetic analysis of 16S rRNA gene sequences showed that strain PB17(T) belonged to the genus Hymenobacter. Sequence similarities between strain PB17(T) and the type strains of Hymenobacter species with validly published names ranged from 90.1 to 91.8 %. The predominant cellular fatty acids in strain PB17(T) were iso-C-15: 0, summed feature 4 (iso-C-15:0 2-OH and/or C-16:1 omega 7c), C-16:1 omega 5c and anteiso-C-15: 0. The DNA G + C content was 58.8 mol%. The results of phylogenetic, chemotaxonomic and phenotypic characterization indicated that strain PB17(T) can be distinguished from all known Hymenobacter species and represents a novel species, for which the name Hymenobacter soli sp. nov. is proposed. The type strain is PB17(T) (=KCTC 12607(T) =LMG 24240(T)).
