A Gram-stain-positive bacterial strain, 11097T, was isolated from traditional pickle in Heilongjiang Province, China. The bacterium was characterized using a polyphasic approach, including 16S rRNA gene sequence analysis, phenylalanyl-tRNA synthase (pheS) gene sequence analysis, RNA polymerase α subunit (rpoA) gene sequence analysis, fatty acid methyl ester (FAME) analysis, determination of DNA G+C content, DNA–DNA hybridization and an analysis of phenotypic features. Strain 11097T was phylogenetically related to Enterococcus devriesei, E. pseudoavium, E. viikkiensis, E. avium, E. malodoratus, E. gilvus and E. raffinosus. Strain 11097T had 99.1–99.9 % 16S rRNA gene sequence similarities, 78.2–83.2 % pheS gene sequence similarities and 93.8–96.6 % rpoA gene sequence similarities with type strains of phylogenetically related species. Based upon polyphasic characterization data obtained in the present study, a novel species of the genus Enterococcus, Enterococcus xiangfangensis sp. nov., is proposed with the type strain 11097T ( = LMG 27495T = NCIMB 14834T).
