Abstract

A novel Gram-stain-negative, non-spore-forming, orange-pigmented bacterium, designated strain SS2-56, was isolated from sediment of the Nakdong River in Sangju-si, Republic of Korea. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the isolate SS2-56 belongs to the family , and was most closely related to H32-4 (96.6 % similarity) and NJ-8 (96.1 %). Strain SS2-56 contained menaquinone 7 (MK-7) as a respiratory quinone and iso-C, iso-C 3-OH, iso-C G, summed feature 3 (C 7 and/or C 6) and C as major fatty acids. The major polar lipids of strain SS2-56 were phosphatidylethanolamine, one unidentified aminophospholipid and four unidentified lipids. The DNA G+C content was 43.8 mol%. Phenotypic, chemotaxonomic and phylogenetic evidence clearly indicates that strain SS2-56 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is SS2-56 (=KCTC 52160=JCM 31372).
