After 72 h incubation at 15 ºC on TSA, colonies are 1.5-2.0 mm in diameter, smooth
and round with irregular edges. Do not produce fluorescent pigment on King’s B
medium.
Aerobic, psychrotolerant. Growth occurs at temperatures between -4 and 30 ºC, but
not at 37 ºC. NaCl is tolerated at concentrations up to 4% (w/v).
