A non-motile, red-pigmented bacterium, designated strain HMD1010T, was isolated from an artificial lake located within the campus of Hankuk University of Foreign Studies, Yongin, Korea. A phylogenetic tree based on 16S rRNA gene sequences showed that strain HMD1010T formed a lineage within the genus Hymenobacter and was closely related to the type strains of Hymenobacter rigui (96.7 % sequence similarity) and H. gelipurpurascens (95.6 %). The major fatty acids were C16 : 1ω5c (21.9 %), summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c; 17.2 %), iso-C15 : 0 (14.5 %) and summed feature 4 (anteiso-C17 : 1 B and/or iso-C17 : 1 I; 11.9 %). The DNA G+C content was 60.4 mol%. On the basis of the evidence presented in this study, strain HMD1010T represents a novel species of the genus Hymenobacter, for which the name Hymenobacter yonginensis sp. nov. was proposed. The type strain is HMD1010T ( = KCTC 22745T  = CECT 7546T).

The novel strains contained MK-11 and MK-12 as the predominant menaquinones and rhamnose, ribose and galactose as the major cell-wall sugars. The major cellular fatty acids (>10 % of the total fatty acids) were anteiso-C15 : 0, iso-C16 : 0 and anteiso-C17 : 0. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and an unidentified glycolipid. The DNA G+C contents were 71.1–71.3 mol%. Phylogenetic trees based on 16S rRNA gene sequences showed that strains UMS-62T and UMS-101 belong to the genus Agromyces. Strains UMS-62T and UMS-101 showed a 16S rRNA gene sequence similarity value of 99.9 % and a mean DNA–DNA relatedness level of 91.1 %. Similarity values between the 16S rRNA gene sequences of the two novel strains and the type strains of recognized Agromyces species ranged from 95.2 to 99.1 %. The levels of DNA–DNA relatedness between the two novel strains and the type strains of five phylogenetically related Agromyces species were in the range of 13.4 to 54.2 %.
