Abstract

A Gram-stain-negative, aerobic, non-motile, non-spore-forming and rod-shaped bacterial strain, designated HKS-05, was isolated from ginseng field soil. This bacterium was characterized to determine its taxonomic position by using the polyphasic approach. HKS-05 grew at 10–37 °C and at pH 6.0–8.0 on R2A agar. On the basis of 16S rRNA gene sequence similarity, HKS-05 was shown to represent a member of the family and to be related to FaiI3 (98.1 % sequence similarity), ‘’ HLK1 (97.9 %), A8 (97.7 %), 4T-6 (97.2 %) and E (97.1 %). The major respiratory quinone was Q-10 and the major fatty acids were summed feature 8 (comprising Cω7 and/or Cω6), C, and summed feature 3 (comprising Cω7 and/or Cω6). The polar lipids were phosphatidylglycerol, unidentified glycolipids and unidentified polar lipids. The G+C content of the genomic DNA was 70.4 mol%. DNA–DNA relatedness values between HKS-05 and its closest phylogenetically neighbours were low. HKS-05 could be differentiated genotypically and phenotypically from the species of the genus with validly published names. The isolate therefore represents a novel species, for which the name sp. nov. is proposed, with the type strain HKS-05 (=KACC 18628=LMG 30081)
