Colonies on TSA after 3 days incubation at 30 ºC, are circular to slightly irregular, flat,
smooth, glistening, greyish-yellow in colour and 3.0-5.0 mm in diameter. Growth
occurs at  1
0-50 ºC, optimally at 30 ºC. Can grow in pH 5.0 and 8.0, optimally in pH
7.0-8.0. Can grow in 0-3% (w/v) NaCl, optimally in 0
-1% NaCl. Facultatively anaerobic.
