Abstract:
A Gram-stain-negative, motile by gliding, yellow-pigmented bacterial strain, designated KNUS1T, was isolated from Lake Paro in Korea. The phylogenetic tree based on 16S rRNA gene sequences showed that strain KNUS1T formed a distinct lineage within the genus Flavobacterium. Strain KNUS1T was closely related to Flavobacterium cheonhonense ARSA-15T (96.8 %16S rRNA gene sequence similarity), Flavobacterium pectinovorum DSM 6368T (96.3 %) and Flavobacterium dankookense ARSA-19T (96.1 %). The major fatty acids of strain KNUS1T were iso-C15 : 0 and iso-C15 : 1 G. The major polyamine was sym-homospermidine. The major polar lipids of strain KNUS1T were phosphatidylethanolamine, five unidentified aminolipids and three unidentified polar lipids. The major respiratory'quinone was menaquinone 6 (MK-6). The DNA G+C content of strain KNUS1T was 34.2 mol%. On the basis of the evidence presented in this study, strain KNUS1T represents a novel species of the genus Flavobacterium, for which the name Flavobacterium paronense sp. nov. is proposed. The type strain is KNUS1T ( = KACC 17692T = CECT 8460T).
