    In this study, samples were collected from Lake Soyang in Kangwon-do in order to isolate novel Flavobacterium sp. strains. Totally, 21 strains of Flavobacterium showing 97%~98% similarity in 16S rRNA were selected and thoroughly investigated individual characteristics and ecological differences. As results, we could categorize Flavobacterium isolated from Lake Soyang into four major node groups, where most of Flavobacterium belonged to single group. Next, fatty acid analyses were performed demonstrating similar pattern of the majority of fatty acids as either iso C15:0 or summed feature 3 (comprised C16:1 ω7c and/or C16:1 ω6c) of the other Flavobacterium. However, other phenotypic data were different from the other Flavobacterium sp. Group. Our data showed that genetically related species of Flavobacterium have been distributed in Lake Soyang. Those Flavobacterium strains were phenotypically different from previously reported genus of Flavobacterium species. Taken together, we speculated that isolated Flavobacterium strains from Lake Soyang might be ecologically important members to maintain ecosystem.
