Description is based on API Coryne and API rapid ID32 Strep results.
Positive results for esculin hydrolysis, alpha- and beta-galactosidase, alpha- and beta-
glucosidase, pyrazinamidase (weak reaction), Voges-Proskauer test (weak reaction), acid production from L-arabinose (weak
reaction), D-glucose, melibiose, D-raffinose, pullulan, ribose (weak reaction), sucrose and D-xylose.
Negative results for arginine dihydrolase, catalase, gelatin hydrolysis, beta-glucuronidase, hippurate hydrolysis, beta-mannosidase,
nitrate reduction, urease, acid production from D-arabitol, methyl-beta-D-glucopyranoside, lactose, mannitol, melezitose, sorbitol,
tagatose and trehalose.
Variable results for alkaline phosphatase, N-acetyl-beta-glucosaminidase, acid production from inositol and maltose.
