Positive results for catalase, citrate utilization, gelatin hydrolysis, nitrates reduction, pectate liquefaction, acid production from: lactose
(delayed), dextrose, mannitol, rhamnose, salicin, sorbitol and sucrose.
Negative results for arginine dihydrolase, indole production, lysine decarboxylase, ornithine decarboxylase, oxidase, phenylalanine
deaminase, urea hydrolysis and acid production from dulcitol.
Different results for H2S production (positive on lead acetate paper and negative in SIM medium).
Variable results for methyl-red test and Voges-Proskauer reaction.
