title: Flavobacterium daemonensis sp. nov., isolated from Daemo Mountain soil.
abstract: A Gram-staining-negative, catalase- and oxidase-positive, obligately aerobic, motile by gliding, bright yellow and rod-shaped bacterial strain was isolated from soil of Daemo Mountain (Daemosan) in Seoul, Republic of Korea. Its taxonomic position was investigated by using a polyphasic study. On the basis of 16S rRNA gene sequence comparisons, strain THG-DJ7(T) was found to be most closely related to Flavobacterium denitrificans ED5(T) (97.9 % sequence similarity), Flavobacterium ginsenosidimutans THG 01(T) (97.6 %), Flavobacterium kyungheensis THG-107(T) (97.5 %), Flavobacterium anhuiense D3(T) (97.1 %) and Flavobacterium ginsengisoli DCY54(T) (97.0 %). The DNA-DNA relatedness between strain THG-DJ7(T) and its phylogenetically closest neighbours was below 40.0 %. The G+C content of the genomic DNA was determined to be 32.6 mol%. The only isoprenoid quinone detected in strain THG-DJ7(T) was menaquinone-6 (MK-6). The major component in the polyamine pattern was sym-homospermidine. The major polar lipids were found to be phosphatidylethanolamine, phosphatidyldimethylethanolamine, an unidentified aminophosphoglycolipid, phosphatidylserine and an unidentified lipid. The major fatty acids were identified as iso-C15 : 0, iso-C15 : 0 3-OH and summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c). These data support the affiliation of strain THG-DJ7(T) to the genus Flavobacterium. We report the phenotypic, genotypic and phylogenetic characterization of strain THG-DJ7(T). Based on the findings presented, a novel species of the genus Flavobacterium, Flavobacterium daemonensis sp. nov. is proposed, with THG-DJ7(T) ( = KACC 17651(T) = JCM 19455(T)) as the type strain.
