Description of Polynucleobacter necessarius subsp. asymbioticus IMCC 26232

Cells are Gram negative and rod shaped. Grows on R 2A at 20°C. Colonies are cream colored, and circular, convex and smooth. Diffusible pigment is not produced. Based on API20NE, cytochrome oxidase activity is positive, but nitrate reduction, indole production, glucose fermentation, arginine dihydrolase, urease, β-glucosidase, protease and β-galactosidase activities are negative. D- Glucose, L-arabinose, D-mannose, D-mannitol, N ­acetyl­glucosamine, D­maltose, potassium gluconate, capric acid, adipic acid, malic acid, trisodium citrate and phenylacetic acid are not assimilated. Strain IMCC 26232 (= NIBRBA 0000114870) was isolated from freshwater.
