Heterofermentative.
Description is based on API 50 CHL (bioMerieux) results.
Positive results for arginine deamination, fermentation of L-arabinose, D-arabitol, D-fructose, glucose (with gas production),
gluconate (with gas production), maltose, ribose, D-xylose, N-acetylglucosamine, and methyl beta-D-xylopyranoside.
Negative results for catalase, fermentation of adonitol, amygdalin, D-arabinose, L-arabitol, arbutin, cellobiose, dulcitol, erythritol,
esculin, L- and D-fucose, gentiobiose, 2- and 5-ketogluconate, glycerol, glycogen, inositol, inulin, D-lyxose, mannitol, melezitose,
melibiose, mannose, methyl alpha-D-mannopyranoside, methyl alpha-D-xyloside, raffinose, rhamnose, sorbitol, L-sorbose, starch,
salicin, sucrose, D-tagatose, trehalose, turanose, xylitol, and L-xylose.
Variable results for the fermentation of galactose, lactose, and methyl alpha-D-glucopyranoside.
