Colonies are yellowish, very thin, slightly roughened, with irregular edges, spreading
to 1-6 mm in diameter. Some colonies may be gelatinous. Colonies are butyrous in

consistency and easily emulsifiable in water. Growth occurrs at 4-28 ºC (optimum, 18
ºC), at pH 4
-11(optimum, 9-10) and in the presence of 0–1 % (w/v) NaCl. Unable to
grow at
30 or 37 ºC. Aerobic; no anaerobic growth on R2A agar. Violet pigment  is not
produced.
