Abstract

A novel actinobacterial strain, designated KGMB04484, was isolated from healthy human faeces sampled in the Republic of Korea. Cells of strain KGMB04484 were strictly anaerobic, Gram-stain-positive, catalase-positive, oxidase-negative, non-motile coccobacilli and formed tiny colonies on Columbia agar with 5 % horse blood. On the basis of 16S rRNA gene sequence similarity, strain KGMB04484 was affiliated with the genus in the family and its closest relative was JC110 (96.28 % sequence similarity). The DNA G+C content of strain KGMB04484 was 61.2 mol%. The polar lipids contained diphosphatidylglycerol, phosphatidylglycerol, an unidentified phospholipid, an unidentified aminolipid and three unidentified glycolipids. The predominant cellular fatty acids (>10 %) of strain KGMB04484 were C, C and C dimethyl acetal. Based on its phylogenetic, physiological and chemotaxonomic characteristics, strain KGMB04484 is considered to represent a novel species within the genus , for which the name sp. nov. is proposed. The type strain is KGMB04484 (=KCTC 15721=CCUG 72347).
