Abstract

A Gram-negative, rod-shaped bacterial strain, YC6729, was isolated from vermicompost collected at Masan, Korea, and its taxonomic position was investigated by a polyphasic taxonomic approach. Strain YC6729 grew optimally at 30 °C and at pH 6.5–8.5. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain YC6729 belongs to the genus in the family . It was related most closely to KP01 (96.4 % 16S rRNA gene sequence similarity), Gsoil 040 (96.1 %), IAM 12650 (96.1 %) and DSM 2588 (93.3 %). Strain YC6729 contained MK-7 as the major menaquinone and homospermidine as the major polyamine. The fatty acids of strain YC6729 were iso-C, Cω5, iso-C 3-OH, C, anteiso-C and/or Cω6,9, iso-C 2-OH and/or Cω7, C, iso-C 3-OH, iso-C G, Cω5, iso-C I and/or C 3-OH, C 2-OH, C 3-OH and unknown fatty acid ECL 13.565. The polar lipid profile contained phosphatidylethanolamine, unknown aminolipids and unknown lipids. The total DNA G+C content of strain YC6729 was 48.9 mol%. The phenotypic, chemotaxonomic and phylogenetic data showed that strain YC6729 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is YC6729 ( = KACC 13774  = DSM 22224).
