Abstract

A Gram-stain-positive, non-motile, coccus-shaped bacterium, strain THG-a14, was isolated from soil of Gyeyang mountain in Incheon, Republic of Korea. The isolate grew optimally at 28 °C, at pH 6.5–7.5 and with 0–3 % (w/v) NaCl. Based on 16S rRNA gene sequence comparisons, strain THG-a14 was closely related to 5516T-20 (97.7 %), BXN5-13 (97.6 %), ‘P. ’ L1b-b9 (97.4 %) and MSL-03 (97.2 %). The DNA G+C content of strain THG-a14 was 71.6 mol%. In DNA–DNA hybridization, the DNA–DNA relatedness between strain THG-a14 and its closest phylogenetically neighbours was below 50.0 %. Strain THG-a14 was characterized chemotaxonomically as having -diaminopimelic acid in the cell-wall peptidoglycan. Strain THG-a14 contained glucose and ribose as whole-cell-wall sugars and menaquinone MK-8(H) as the major isoprenoid quinone. Polar lipids in strain THG-a14 consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphoaminoglycolipids, unidentified phospholipids and unidentified lipids. The major fatty acids were iso-C , iso-C and C ω8. On the basis of our polyphasic taxonomy study, strain THG-a14 represents a novel species within the genus , for which the name sp. nov. is proposed. The type strain is THG-a14 ( = KACC 17892 = JCM 19837).
