sp. nov., isolated from from lake sediment.

An aerobic and Gram-stain-negative bacterial strain, designated UKS-15, was isolated from lake water in the Republic of Korea. Results of 16S rRNA gene sequence and phylogenetic analyses indicated that the novel isolate belongs to the genus and was most closely related to RCML-52 (98.0 %), 9 NM-14 (97.4 %) and FJY8 (97.2 %). The DNA G+C content was 69.1 mol%. Strain UKS-15 possessed ubiquinone-8 (Q-8) as the sole respiratory quinone and the fatty acid profile comprised iso-C, iso-C and summed feature 9 (iso-C ω9 and/or C 10-methyl) as its major components. The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and one unidentified aminophospholipid. Moreover, the physiological and biochemical results and low level of DNA-DNA relatedness (<22.0 %) allowed the phenotypic and genotypic differentiation of strain UKS-15 from other species. Therefore, on the basis of the data from this polyphasic taxonomic study, strain UKS-15 should represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is UKS-15 (=JCM 30983=KACC 18719).
