Abstract

A polyphasic taxonomic study was carried out on strain EBR-4-1, which was isolated from a biofilm reactor in the Republic of Korea. The cells of the strain were Gram-stain-negative, non-spore-forming, motile and rod-shaped. Comparative 16S rRNA gene sequence studies showed a clear affiliation of this strain to the , and it was most closely related to CCUG 54519, HT4, and DSM 6462 with 16S rRNA gene sequence similarities to the type strains of these species of 98.8 %, 98.7 %, and 96.3 %, respectively. The G+C content of the genomic DNA of strain EBR-4-1 was 68.7 mol%. Phenotypic and chemotaxonomic data [Q-10 as the major ubiquinone; Cω8, C 2-OH, and summed feature 8 (Cω7 and/or Cω6) as the major fatty acids] supported the affiliation of strain EBR-4-1 to the genus . On the basis of the polyphasic evidence, it is proposed that strain EBR-4-1 should be assigned to a new species, sp. nov. The type strain is EBR-4-1 ( = KCTC 32487 = JCM 30181).
