Anseongella ginsenosidimutans gen. nov., sp. nov., isolated from soil cultivating ginseng.

ABSTRACT

A Gram-stain-negative, rod-shaped, non-spore-forming, oxidase and catalase-positive, strictly aerobic bacterium, designated strain Gsoil 524T, was isolated from the soil of a ginseng field and subjected to polyphasic taxonomic analysis. Phylogenetic analysis, based on the 16S rRNA gene sequence, placed Gsoil 524T in a distinct lineage in the family Sphingobacteriaceae, sharing 87.2-88.0 % sequence similarity with members of the closely related genera Pedobacter, Mucilaginibacter and Solitalea. Strain Gsoil 524T contained MK-7 as the predominant quinone, and iso-C15 0, iso-C17 0 3-OH, summed feature 3 (C16 1ω7c and/or C16 1ω6c) and C16 1ω5c as the major fatty acids. Strain Gsoil 524T could be distinguished from the other members of the family Sphingobacteriaceae by a number of chemotaxonomic and phenotypic characteristics. The major polar lipids in strain Gsoil 524T were phosphatidylethanolamine and two unidentified polar lipids. Compared with the standard and reference strains unidentified sphingolipid was also found. Based on this polyphasic taxonomic analysis, strain Gsoil 524T represents a novel species within a novel genus, for which the name Anseongella ginsenosidimutans gen. nov., sp. nov. is proposed. The type strain of Anseongella ginsenosidimutans is Gsoil 524T ( = KACC 14636T = KCTC 22261T = LMG 24494T).
