Haloferax elongans MBLA

Description of Haloferax elongans MBLA View in CoL 0250

Cells are Gram-stain-negative and pleomorphic-coccus shaped with 1.7 - 1.9 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 25 - 50℃ (optimum, 37℃) at 10 - 30% 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-fructose, D-sucrose, L-rhamnose, D-sorbitol, fumarate, pyruvate, glycine, L-histidine D-xylose, glycerol, DL-lactate, succinate, pyruvate, DL-malate, fumarate, citrate, acetate, and L-alanine are utilized as sole energy sources for growth, but D-galactose, D-maltose, lactose, D-mannose, D-xylose, D-trehalose, D-raffinose, D-mannitol, glycerol, starch, citrate DL-lactate, acetate, succinate, L-alanine, L-arginine, L-ornithine, L-asparagine, L-glutamine, and L-glutamic acid are not utilized. The NCBI accession number for the 16S rRNA gene sequence is OR646565. Strain MBLA0250 (=NIBRARC000510482) was isolated from seawater near Dokdo island , Korea (37°14 ʹ 29.4 ʺ N 131°52 ʹ 00.9 ʺ E) GoogleMaps .
