ABSTRACT
A Gram-stain-negative, facultatively anaerobic, non-motile, rod-shaped and yellow-pigmented bacterium, designated strain THG-DN6.14T, 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-DN6.14T was found to be most closely related to Emticicia sediminis JBR12T (99.1â% sequence similarity), Emticicia oligotrophica DSM 17448T (97.6â%), Emticicia aquatica HMF2925T (96.5â%), and Emticicia ginsengisoliGsoil 085T (94.4â%). The DNA-DNA relatedness between THG-DN6.14T and its phylogenetically closest neighbours was below 65.0â%. 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 C16ââ0, iso-C15ââ0, iso-C17ââ0 3-OH, and summed feature 3 (C16ââ1ω7c and/or C16ââ1ω6c). The respiratory quinone was menaquinone MK-7. These data supported the affiliation of THG-DN6.14T to the genus Emticicia. THG-DN6.14Tcould be distinguished from related species of the genus Emticicia by physiological and biochemical tests. Therefore, the novel isolate represents a novel species, for which the name Emticicia aquatilis sp. nov. is proposed, with THG-DN6.14T (=KACC 18540T=CGMCC 1.15958T) as the type strain.
