A Gram-negative, rod-shaped bacterial strain, K105T, was isolated from wastewater of a textile dye works in Korea and subjected to a polyphasic taxonomic study. Strain K105T grew optimally at pH 6.5–7.5 and 30–37 °C. It contained MK-6 as the predominant menaquinone and iso-C15 : 0, iso-C17 : 1 ω9c, iso-C17 : 0 3-OH and summed feature 3 (C16 : 1 ω7c and/or iso-C15 : 0 2-OH) as the major fatty acids. The DNA G+C content was 36.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain K105T belonged to the genus Chryseobacterium. Strain K105T exhibited 16S rRNA gene sequence similarity values of less than 96.9 % to the type strains of recognized Chryseobacterium species. Strain K105T differed from phylogenetically related Chryseobacterium species in several phenotypic properties. On the basis of phenotypic and phylogenetic data, strain K105T (=KCTC 12841T=JCM 14362T) is placed in the genus Chryseobacterium as the type strain of a novel species, for which the name Chryseobacterium daeguense sp. nov. is proposed.

A Gram-negative, non-sporulating, non-flagellated rod, designated BR-9T, was isolated from soil collected on the Korean peninsula. Strain BR-9T grew optimally at pH 6.0–7.0, at 30 °C and in the absence of NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain BR-9T belonged to the genus Pedobacter and clustered with Pedobacter insulae DS-139T and Pedobacter koreensis WPCB189T. Strain BR-9T exhibited 98.2 and 97.5 % 16S rRNA gene sequence similarity with P. insulae DS-139T and P. koreensis WPCB189T, respectively, and <96.7 % sequence similarity with the type strains of other species in the genus Pedobacter. Strain BR-9T contained MK-7 as the predominant menaquinone and iso-C15 : 0 and summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH) as the major fatty acids.

DNA–DNA relatedness between strain BR-9T and P. insulae DS-139T and P. koreensis KCTC 12536T was 3.4–4.2 %, which indicated that the isolate was genetically distinct from these type strains. Strain BR-9T was also distinguishable by differences in phenotypic properties. On the basis of the data presented, strain BR-9T is considered to represent a novel species of the genus Pedobacter, for which the name Pedobacter boryungensis sp. nov. is proposed. The type strain is BR-9T ( = KCTC 23344T  = CCUG 60024T).

The DNA G+C content was 69.3 mol%. A phylogenetic analysis based on 16S rRNA gene sequences showed that strain DS-48T fell within the genus Roseomonas, clustering with Roseomonas lacus TH-G33T (at a bootstrap confidence level of 100 %). The levels of similarity between the 16S rRNA gene sequence of strain DS-48T and those of the type strains of recognized Roseomonas species were in the range 93.2–98.0 %. DNA–DNA relatedness data and differential phenotypic properties, together with the phylogenetic distinctiveness of DS-48T, revealed that this strain differs from recognized Roseomonas species. On the basis of phenotypic, phylogenetic and genetic data, therefore, strain DS-48T represents a novel species within the genus Roseomonas, for which the name Roseomonas terrae sp. nov. is proposed. The type strain is DS-48T (=KCTC 12874T=JCM 14592T).
