Abstract

A Gram-reaction-positive, aerobic, coccus- to rod-shaped, non-motile, non-spore-forming bacterium (strain UKS-03) was isolated from a sediment sample of Ungok Lake in Gochang, Republic of Korea. The taxonomic position of this bacterium was determined in an investigation based on a polyphasic approach. On the basis of 16S rRNA gene sequence analysis, strain UKS-03 was shown to belong to the family and to be related most closely to Gsoil 485 (98.5 % similarity), MSL-09 (98.4 %) and ‘’ Gsoil 958 (97.3 %). Strain UKS-03 was characterized chemotaxonomically as having -2,6-diaminopimelic acid in its cell-wall peptidoglycan, MK-8(H) as the predominant menaquinone, diphosphatidylglycerol and phosphatidylglycerol as the main polar lipids, and iso-C, Cω8 and C 10-methyl as its major fatty acids. The G+C content of the genomic DNA was 71.9 mol%. Mean DNA–DNA relatedness values between strain UKS-03 and Gsoil 485, KCTC 19272 and ‘’ Gsoil 958 were 37.5 ± 7.2, 6.8 ± 0.9 and 3.1 ± 0.7 %, respectively. On the basis of the data from this polyphasic taxonomic study, strain UKS-03 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is UKS-03 ( = KACC 18304 = LMG 28591).
