Abstract

A Gram-stain-negative, rod-shaped, pale yellow, aerobic bacterial strain, JC2902T, was isolated from a sediment sample of Ungok Lake in Gochang, Republic of Korea. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain JC2902T belongs to the genus Flavobacterium and forms a distinct phyletic line within a clade containing four recognized species of the genus Flavobacterium. The genomic relatedness between strain JC2902T and closely related strains was calculated using average nucleotide identity values of whole genome sequences, which indicated that the new isolate represents a novel genomic species. Through comparison of chemotaxonomic and other phenotypic characteristics between strain JC2902T and the type strains of the four phylogenetically related species, a number of characteristics differentiated strain JC2902T from the previously described type strains. Differential characteristics of strain JC2902T include fatty acid profiles, cellular motility, inability to grow on Luria-Bertani and tripticase soy agar media, and absence of N-acetyl-β-glucosaminidase and flexirubin-type pigments. Based on data from this polyphasic taxonomic study, strain JC2902T is considered to represent a novel species of the genus Flavobacterium, for which the name Flavobacterium limnosediminis sp. nov. is proposed. The type strain is JC2902T (= KACC 16937T = JCM 18661T).
