A novel bacterial strain designated HME7863(T) was isolated from a freshwater reservoir in Goheung, Republic of Korea. Cells of strain HME7863(T) were Gram-staining-negative, strictly aerobic, orange-pigmented, rod-shaped and motile by gliding. Phylogenetic analysis based on 16S rRNA gene sequence showed that strain HME7863(T) formed a lineage within the genus Sediminibacterium. Strain HME7863(T) was closely related to Sediminibacterium ginsengisoli DCY13(T) (96.9 % sequence similarity) and Sediminibacterium salmoneum NJ-44(T) (96.4 %). The major cellular fatty acids were iso-C15 : 1 G, iso-C15 : 0, iso-C17 : 0 3-OH and iso-C16 : 0 3-OH. Polar lipid analysis revealed the presence of phosphatidylethanolamine, five unidentified aminolipids, two unidentified aminophospholipids, one unidentified phospholipid and two unidentified polar lipids. The only respiratory quinone was MK-7. The DNA G+C content was 40.5 mol%. On the basis of the evidence presented in this study, strain HME7863(T) represents a novel species of the genus Sediminibacterium, for which the name Sediminibacterium goheungense sp. nov., is proposed. The type strain is HME7863(T) ( = KCTC 23945(T) = CECT 8100(T)).
