Colonies are circular, convex, smooth, opaque and white colored after incubation for 2 days on marine agar at 25℃. In the API 20NE system, positive reaction for urease activity, hydrolysis of esculin and gelatin and utilization of D-glucose, D-mannose, D-mannitol and D­maltose. In the API 20NE system, negative reaction for nitrate reduction, indole production, glucose fermentation, arginine dihydrolase, β-galactosidase activity, oxidase activity and utilization of L-arabinose, N ­acetyl­glucosamine, potassium gluconate, capric acid, adipic acid, malic acid, trisodium citrate and phenylacetic acid. Strain KYW1971 ( = NIBRBAC000503307) was isolated from seawater in Gwangyang , Jeollanam Province , Korea ( 34° 54′24.83″N 127°44′01.47″E ).
