Abstract

A Gram-positive, aerobic, non-motile and coccoid actinobacterium, designated P31, was isolated from a traditional, fermented seafood. The strain was catalase-positive and oxidase-negative. Cells grew in the presence of 0–15.0 % (w/v) NaCl, and at pH 5–10 and 15–37 °C. Major cellular fatty acids were anteiso-C, anteiso-C and iso-C. Strain P31 contained MK-7 as the predominant menaquinone. The DNA G+C content of the genomic DNA of strain P31 was 65.2 mol%. A phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain P31 was most closely related to DSM 20032, with 96.9 % similarity, and these two strains clustered together in constructed phylogenetic trees. The DNA–DNA hybridization value between strain P31 and DSM 20032 was 21.1 %. On the basis of the phenotypic, chemotaxonomic and phylogenetic data, it is suggested that strain P31 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is P31 (=KCTC 19595=JCM 15915).
