Abstract

Two strains of species of the genus , designated KIS18-7 and JOS5-1, were isolated from soil samples in Korea. The 16S rRNA gene sequence of strain KIS18-7 showed highest similarities with Sco-D01 (97.8 %), SST-45 (97.6 %) and BC 361 (97.3 %), and strain JOS5-1 had highest sequence similarities with SST-45 (97.5 %) and MSL-05 (97.3 %). The sequence similarity between KIS18-7 and JOS5-1 was 98.1 %. Phylogenetic analysis showed that these strains grouped with species of the genus . The major fatty acids of strain KIS18-7 were iso-C and Cω8, and Cω8, C 10-methyl (TBSA), Cω9, C 10-methyl and C 2-OH for strain JOS5-1. Strain KIS18-7 contained the polar lipids, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol and phosphatidylcholine, while strain JOS5-1 contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, one unknown aminolipid and two unknown phospholipids. The peptidoglycan of both strains contained -diaminopimelic acid as the diagnostic diamino acid and a single glycine residue as the interpeptide bridge (type A3γ). The major menaquinone of both strains was MK-8(H). The G+C contents of the DNA of strains KIS18-7 and JOS5-1 were 68.0 mol% and 62.9 mol%, respectively. These data demonstrate that strains KIS18-7 and JOS5-1 are representatives of two novel species of the genus , for which the names sp. nov. (type strain KIS18-7 = KACC 17307 = DSM 27140 = NBRC 109601) and sp. nov. (type strain JOS5-1 = KACC 17308 = DSM 27141 = NBRC 109602) are proposed.
