Description is based on API CORYNE (2000324), API 50CH and API ZYM tests.
Fermentative metabolism.
Positive results for catalase, cystine arylamidase, esterase (C4), ester lipase (C8), leucine arylamidase (weak reaction), lipase,
pyrazinamidase, acid production from: fructose, glucose (at 37 and 42 ºC), N-acetyl-beta-glucosamine, maltose, mannose, ribose
and trehalose.
Negative results for acid phosphatase, alkaline phosphatase, aesculin hydrolysis, chymotrypsin, alpha- and beta-galactosidase,
alpha- and beta-glucosidase, beta-glucuronidase, N-acetyl-beta-glucosaminidase, gelatin hydrolysis, lipophilic reaction, nitrate
reduction, pyrrolidonyl arylamidase, trypsin, urease, valine arylamidase, acid production from: D- and L-arabinose, arabitol, arbutin,
adonitol, amygdalin, cellobiose, erythritol, L- and D-fucose, galactose, gentiobiose, glycerol, glycogen, 2- and 5-ketogluconate,
inositol, inulin, lactose, lyxose, mannitol, melezitose, melibiose, raffinose, rhamnose, salicin, sorbitol, L- sorbose, sucrose, tagatose,
turanose, xylitol and xylose.
Acid production from dulcitol is variable.
