Growth occurs at 08-40 ºC. Aerobic.  No anaerobic growth using nitrate. Can grow in
the presence of 1% bile but not in 1% glycine or 3% NaCl. Can grow on EMB and TSI,
but not in MacConkey agar, Sellers agar or in MRVP broth. Range of pH: 5.5-8.5.  
Water-soluble yellow-green fluorescent pigment is not produced. No pigment is
produced from aromatic amino acids.
