Two growth-phase-dependent colony forms are present, one convex with undulate
margins that changes to convex circular over a 48 h period. Good growth occurs on
LB agar at 25-42 ºC.

Description is based mostly on API 20 E (Biomerieux) results, profile 1307160 (admin note: in the original paper the profile is
erroneously cited as 3107160).
Positive results for citrate utilization, beta-galactosidase (ONPG), gelatin hydrolysis, ornithine decarboxylase, Voges-Proskauer test,
acid production from: cellobiose, glucose, glycerol, lactose, mannitol, melibiose, raffinose , sucrose and trehalose.
Negative results for arginine dihydrolase, DNase, H2S production, indole production, lysine decarboxylase, malonate utilization,
oxidase, urease, acid production from: amygdalin, L-arabinose, aesculin, inositol, rhamnose, salicin, sorbitol, sorbose, and D-xylose.
