Original Paper


An aerobic, Gram-stain-negative, bright yellow-pigmented, oxidase and catalase-positive, non-motile, non-spore forming, rod-shaped strain designated DMN11T was isolated from the soil of crossroads of Jeju Island in South Korea. Colonies were circular, bright yellow-pigmented and smooth with regular edges and measured approximately 1–2 mm in diameter. Flexirubin-type pigments were absent. Phylogenetic tree analysis based on the 16SrRNA gene sequence revealed that the strain DMN11T formed a lineage within the family Flavobacteriaceae of the phylum Bacteroidetes, and it was the most closely related to Flavobacterium suzhouense XIN-1T and Flavobacterium hauense BX12T (98.6% and 98.2% similarity, respectively). The major isoprenoid quinone was MK-6. The major fatty acids were summed feature 3 (comprising C16:1 ω7c and/or C16:1 ω6c), iso-C15:0 and iso-C15:0 3OH. The polar lipid profile of the strain DMN11T showed the presence of phosphatidylethanolamine (PE) as major lipid. The DNA G+C content was 35.3 mol%, as determined by the thermal denaturation method. The mean levels of DNA–DNA relatedness of the strain DMN11T with F. suzhouense XIN-1T and F. hauense BX12T were 20.5% and 29.2%, respectively. Thus, the data accumulated in this study support the suggestion that the strain DMN11T is considered to represent a novel species of the genus Flavobacterieum, for which the name Flavobacterium edaphi sp. nov. is proposed. The type strain is DMN11T (= KCTC 62114T = JCM 32372T).
