Abstract

Gram-negative, non-spore-forming, rod-shaped, yellow-pigmented bacteria isolated from a freshwater stream in Korea were investigated to determine their taxonomic position. Complete 16S rRNA gene sequence analysis indicated that the organisms should be placed in the branch in the family . Phylogenetically, the strains were most closely related to ATCC 33487 and LMG 13028 (94·3 and 94·1 % 16S rRNA gene sequence similarity, respectively) and they clustered on a separate well-supported branch. The strains contained menaquinone MK-6 as the predominant respiratory quinone and showed higher G+C contents (41·7 mol%) than other species in the branch and i-C as a major fatty acid (47–52 %). The phylogenetic distances from any species with validly published names and their phenotypic properties confirmed that the strains constitute a separate species in a new genus, for which the name gen. nov., sp. nov. is proposed (type strain Chj707=KCTC 12107=IAM 15050).
