Flavobacterium sediminis MEBiC7310 sp. nov., a Marine Bacterium Isolated from a Tidal Flat Sediment

Abstract

A Gram-negative, rod-shaped, yellow-pigmented marine bacterium MEBiC07310T was isolated from tidal flat sediments in Taean province, South Korea. Phylogenetic analysis based on the 16S rRNA gene sequences indicated that strain MEBiC07310T was affiliated with members of genus Flavobacterium and showed that the strain was most closely related to Flavobacterium haoraii LQY-73T (96.7%) and followed by Flavobacterium indicum GPTSA 100-9T (95%) and Flavobacterium cucumis R2A45-3T (92.5%). Growth was observed at 17&#8211 43°C, at pH 5&#8211 48, and with 0&#8211 43% NaCl. The major fatty acids of strain MEBiC07310T were iso-C15:0, iso-C15:0 3-OH, iso-C17:0 3-OH, summed feature 1 (iso-C15:1 H and/or C13:03-OH) and summed feature 3 (C16:1ω6c and/or C16: 1ω7c). The G+C content of genomic DNA was 33.7% and major respiratory quinone was MK-6. On the basis of these characteristics, Flavobacterium sediminis MEBiC7310 sp. nov. is proposed.as affiliated with members of genus Flavobacterium and showed that the strain was most closely related to Flavobacterium haoraii LQY-73T (96.7%) and followed by Flavobacterium indicum GPTSA 100-9T (95%) and Flavobacterium cucumis R2A45-3T (92.5%).
