Abstract

A non-motile and rod-shaped bacterium, designated strain WW84, was isolated from freshwater collected from the Woopo wetland (Republic of Korea). Cells were Gram-stain-negative, aerobic, catalase-positive and oxidase-negative. The major fatty acids were C16 : 0, C18 : 0, iso-C15 : 0 and iso-C17 : 1I and/or anteiso-C17 : 1B. The strain contained MK-7 as the major isoprenoid quinone, phosphatidylethanolamine as the major polar lipid and sym-homospermidine as the major polyamine. The DNA G+C content was 59 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain WW84 forms an evolutionary lineage within the radiation including the members of the genus Hymenobacter with Hymenobacter o cellatus Myx 2105 (96.96 % sequence similarity) as its nearest neighbor. A number of phenotypic characteristics distinguished strain WW84 from the related members of the genus Hymenobacter . On the basis of the evidence presented in this study, a novel species, Hymenobacter coalescens sp. nov. is proposed with strain WW84 (=KCTC 32530=JCM 19493) as the type strain.
