Most biochemical reactions were determined by API Coryne and API ZYM tests.
Positive results for acid phosphatase (weak), catalase, esculin hydrolysis, esterase C4 (weak), ester lipase C8 (weak),
beta-glucosidase, nitrate reduction, acid production from: glucose, maltose, ribose & sucrose.

alpha-galactosidase, beta-galactosidase, beta-glucuronidase, gelatin hydrolysis, lipophilic reaction, pyrazinamidase, urease, acid
production from: glycogen, lactose, mannitol & xylose.
Variable results for alpha-glucosidase.
