Abstract

Two Gram-stain-negative, oxidase-negative, catalase-positive, aerobic and coccus-shaped bacterial strains, KSY3-6 and JSH6-18, were isolated from soil in South Korea. Strains KSY3-6 and JSH6-18 showed high resistance to gamma-ray and UVC irradiation. The 16S rRNA gene sequences of strains KSY3-6 and JSH6-18 showed a novel subline within the genus in the family . They shared 94.8–86.4 % nucleotide similarities with other species of the genus . Strain KSY3-6 exhibited high DNA–DNA hybridization values with JSH6-18 (77±0.8 %). The two strains showed typical chemotaxonomic characteristics of the genus , including the presence of menaquinone 8 (MK-8) as predominant respiratory quinone and C, Ccyclo and summed feature 3 (C 7/C 6) as major fatty acids. The G+C content of the DNA of strains KSY3-6 and JSH6-18 was 62.0 and 62.4 mol%, respectively. Polar lipids in strains KSY3-6 and JSH6-18 were mainly phosphoglycolipids. Based on their phenotypic and genotypic properties, strains KSY3-6 and JSH6-18 should be classified as representatives of a novel species in the genus , for which the name sp. nov. is proposed. The type strain is KSY3-6 (=KCTC 33787=JCM 31313). The reference strain is JSH6-18 (=KCTC 33788=JCM 31312).
