Positive results for oxidase, acid production (API CHB) from: cellobiose, sucrose,
maltose, starch, 5-keto-gluconate and potassium gluconate.
Can assimilate (API 20 NE): maltose, glucose, gluconate, and adipic acid.
Negative results for catalase, urease, acid production from: D- and L-arabinose, L-xylose, D-fructose and D-mannose.
No assimilation of: malic acid, sodium citrate, or mannitol.
