Positive results: gas and acid production from D-glucose, production of H2S, production
of indole, nitrate reduced, maltose utilization for fermentation, sucrose utilization for
fermentation, glucose use for fermentation & phenylalanine deaminase.
Negative results: cannot use lactose, arabinose, gelatin, casein or starch for fermentation , urease, catalase, oxidase & lysine
decarboxylase.
