Positive results for nitrate reduction to nitrite (no denitrification), cytochrome oxidase,
catalase,  esterase-lipase, urease & arginine dihydrolase, assimilation of:  D-xylose,
sucrose, adonitol, DL-alpha-amino-N-butyrate & trigonelline.
Levan is produced from sucrose.

benzoate, L-tryptophan, D-tartrate & meso-tartrate.

Variable results for lecithinase,gelatinase & assimilation of alpha-L-rhamnose.
