Haloferax namakaokahaiae MBLA

Description of Haloferax namakaokahaiae MBLA 0252

Cells are Gram-stain-negative and coccus-shaped with 1.1 - 1.2 μm in diameter. Colonies are red, circular, and flat after 3 days of incubation on DBCM2 at 37℃. Catalase is positive, but oxidase is negative. Growth occurs in the 20 - 40°C (optimum, 37°C) at 5 - 25% NaCl (optimum, 15%) at pH 6.0 - 8.0 (optimum, pH 7.0) and lysed in distilled water. Mg 2+ is required for growth. D-Glucose, D-galactose, D-fructose, D-sucrose, lactose, D-xylose, Lrhamnose, D-raffinose, D-sorbitol, starch, fumarate, pyruvate, DL-malate, acetate, glycine, L-ornithine, L-asparagine, L-glutamine, and L-glutamic acid are utilized as sole energy sources for growth, but D-maltose, D-mannose, D-trehalose, D-mannitol, glycerol, DL-lactate, citrate, succinate, L-alanine, and L-histidine are not utilized. The NCBI accession number for the 16S rRNA gene sequence is OR646567. Strain MBLA0252 (= NIBRARC000510484) was isolated from seawater near Dokdo island , Korea (37°14 ʹ 29.4 ʺ N 131°52 ʹ 00.9 ʺ E) GoogleMaps .
