Abstract

A Gram-negative, aerobic, rod-shaped, non-spore-forming bacterium, Slu-01, was isolated from activated sludge from a wastewater treatment plant in Daejeon, South Korea. After 3 days on R2A medium, strain Slu-01 developed colourless colonies (0·7–1·2 mm). The non-motile rods (0·7–1·0×1·0–2·0 μm) were slightly curved and occurred singly and in pairs. No filamentous cells were found. On the basis of 16S rRNA gene sequence similarity, strain Slu-01 was shown to belong to the family and was most closely related to (96·6 %) and (96·5 %). The genomic DNA G+C content of strain Slu-01 was 68·1 mol%, within the range of 67·3–68·4 mol% for the genus . Chemotaxonomic data (major ubiquinone, Q-10; major fatty acids C 7, C, C and C) and 16S rRNA gene sequence analysis supported the affiliation of strain Slu-01 to the genus . However, DNA–DNA hybridization data and phenotypic properties showed that strain Slu-01 could be distinguished from the two other species with validly published names. Thus, it is suggested that strain Slu-01 represents a novel species of the genus , for which the name is proposed. The type strain is Slu-01 (=KCTC 12206=IAM 15119).
