Abstract

A cream-coloured, Gram-stain-negative, rod-shaped bacterium, designated strain KSC-6, was isolated from soil sampled at the Gapcheon River watershed in Daejeon, Republic of Korea. The organism does not require NaCl for growth and grows at pH 6.0–8.0 (optimum, pH 7.0) and 10–37 °C (optimum, 25 °C). Phylogenetic trees based on the 16S rRNA gene sequences reveal that strain KSC-6 belongs to the family within the order and is most closely related to Gsoil 1550 (95.9% similarity). The genomic DNA G+C content was 38.9 mol%. The major cellular fatty acids (>8 %) of strain KCS-6 were iso-C iso-C G and iso-C 3-OH. The predominant respiratory quinone was menaquinone 7 and the predominant polar lipids were phosphatidylethanolamine, five unidentified aminolipids and two unidentified lipids. Based on genome analyses, low digital DNA–DNA hybridization, average nucleotide identity and average amino acid identity values with closely related genera, and differential chemotaxonomic and physiological properties, we suggest that strain KCS-6 represents a novel species in a new genus in the family , for which the name gen. nov., sp. nov. (type strain KCS-6=KCCM 43337=NBRC 114336) is proposed.
