Abstract
A novel yellow-colored, Gram-stain-negative, aerobic, non-motile, catalase- and oxidase-positive, and rod-shaped psychrotolerant bacterium, designated strain PLR-18-3T, was isolated from Arctic soil and was subjected to polyphasic taxonomic study. Cells were able to grow at 0–30 °C, pH 6.0–10.5, and 0–3.0% (w/v) NaCl concentration. Based on the 16S rRNA gene sequence analysis, this Arctic strain belonged to the genus Flavobacterium, with the closest neighbor being Flavobacterium noncentrifugens R-HLS-17T (96.2% sequence similarity). The strain contained MK-6 as a sole respiratory quinone, phosphatidylethanolamine as the major polar lipid, and summed feature 3 (C16:1ω7c and/or C16:1ω6c), iso-C15:0, iso-C15:0 G, iso-C17:0 3-OH, iso-C15:0 3-OH, anteiso-C15:0, and summed feature 9 (iso-C17:1ω9c and/or C16:010-methyl) as the predominant fatty acids. The DNA G + C content was 37.9 mol%. On the basis of polyphasic data, strain PLR-18-3T represents a novel species of the genus Flavobacterium, for which the name Flavobacterium dasani sp. nov. is proposed. The type strain is PLR-18-3T (=KEMB 9005-713T=KACC 19627T=NBRC 113347T).
