No fermentative metabolism.
Most biochemical characters were tested on API Coryne and API ZYM.
Positive results for acid phosphatase, alkaline phosphatase, catalase, esterase
lipase (C8) (weak), hippurate hydrolysis, and acid production from glucose.
Negative results for gelatin hydrolysis, lipophilism, nitrate reduction, pyrazinamidase, starch hydrolysis, urease, Voges-Proskauer
reaction, acid production from: glycogen, lactose, maltose, sucrose, mannitol, ribose & xylose.
Esculin hydrolysis is variable.
