Abstract

A Gram-stain-negative, facultatively anaerobic, non-motile, rod-shaped and yellow-pigmented bacterium, designated strain THG-DN6.14, was isolated from a freshwater sample near Donghaksa temple in Daejeon, South Korea. On the basis of the results of 16S rRNA gene sequence comparisons, THG-DN6.14 was found to be most closely related to JBR12 (99.1 % sequence similarity), DSM 17448 (97.6 %), HMF2925 (96.5 %), and Gsoil 085 (94.4 %). The DNA–DNA relatedness between THG-DN6.14 and its phylogenetically closest neighbours was below 65.0 %. The DNA G+C content was 43.3 mol%. The major polar lipids were found to be phosphatidylethanolamine, an unidentified glycolipid and an unidentified aminoglycolipid. The major fatty acids were identified as C, iso-C, iso-C 3-OH, and summed feature 3 (Cω7 and/or Cω6). The respiratory quinone was menaquinone MK-7. These data supported the affiliation of THG-DN6.14 to the genus . THG-DN6.14could be distinguished from related species of the genus by physiological and biochemical tests. Therefore, the novel isolate represents a novel species, for which the name sp. nov. is proposed, with THG-DN6.14 (=KACC 18540=CGMCC 1.15958) as the type strain.
