Growth occurs at 09-37 ºC. Aerobic.  No anaerobic growth using nitrate. Can grow in
the presence of 1% bile but not in 1% glycine or 3% NaCl. Cannot grow on EMB, TSI,  
MacConkey and Sellers agars or in MRVP broth. Range of pH: 6.0-9.0. Water-soluble
yellow-green fluorescent pigment is not produced. No pigment is produced from
aromatic amino acids.
