Grows on R 2A at 25°C. Colonies are white colored, and irregular, umbonate and lobate. Diffusible pigment is not produced. Based on API20NE, cytochrome oxidase and nitrate reduction activities are positive, but indole production, glucose fermentation, arginine dihydrolase, urease, β-glucosidase, protease and β-galactosidase activities are negative. Capric acid and malic acid are assimilated, but not D-glucose, L-arabinose, D-mannose, D-mannitol, N ­acetyl­glucosamine, D­maltose, potassium gluconate, adipic acid, trisodium citrate and phenylacetic acid. Strain WS99 ( = NIBRBA 0000115015) was isolated from freshwater. The 16S rRNA gene sequence accession number is KP099964.
