A novel strain, designated HMF3095 T , isolated from freshwater of a mesotrophic artificial lake in the Republic of Korea, was characterized by polyphasic taxonomy. The cells were Gram-stain-negative, aerobic, non-motile, straight rods and formed reddish colonies. Phylogenetic analysis based on its 16S rRNA gene sequence revealed that strain HMF3095 T fell within the cluster of the genus Hymenobacterand was most closely related to Hymenobacter seoulensis 16F7G T and Hymenobacter tenuis POB6 T (96.7 % sequence similarity). Sequence similarities to all other type strains were 96.3 % or less. The major fatty acids were iso-C15 : 0, C16 : 1ω5c, summed feature 4 (iso-C17 : 1 I and/or anteiso-C17 : 1 B), summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and anteiso-C15 : 0. The major isoprenoid quinone was menaquinone 7. The major polar lipids were phosphatidylethanolamine, three unidentified aminophospholipids and one unidentified phospholipid. The DNA G+C content was 58.9 mol%. On the basis of the evidence presented in this study, strain HMF3095 T represents a novel species of the genus Hymenobacter, for which the name Hymenobacter aquatilis sp. nov. is proposed. The type strain is HMF3095 T (=KCTC 52398 T =NBRC 112669 T ).
