Abstract

The yellow-pigmented, Gram-stain-negative, rod-shaped bacterium KJ1R5 was isolated from the root of a pepper plant grown in a field in Kwangju, Korea. Strain KJ1R5 was characterized by physiological, biochemical, and molecular genetic analyses. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain KJ1R5 was most closely related to members of the genus , and that the strain exhibited the highest similarities with type strains of (97.0 %) and (97.1 %). DNA–DNA hybridization reassociation values between strain KJ1R5 and type strains of KACC 11675 and KACC 14918 were 46.9 and 38.4 %, respectively. The DNA G+C content of KJ1R5 is 40.2 mol%. The predominant respiratory quinone of KJ1R5 was menaquinone MK-6; major cellular fatty acids were iso-C, summed feature 3 (Cω7 and/or Cω6), iso-Cω9, and iso-C 3-OH. On the basis of these phenotypic and genotypic characteristics, the strain significantly differed from representative strains belonging to the genus . Thus, we propose that strain KJ1R5 represents a novel species of the genus , named sp. nov. The type strain is KJ1R5 ( = KACC 13029 = JCM 15904).
