Colonies are round, entire, raised, smooth, and shiny,1 mm in diameter (uncrowded
growth) after 24 h, 2 mm in diameter after 48 h and 10 mm after 1 to 2 weeks.
Produce a deep royal blue with a metallic copper-colored sheen at 36 to 48 h, due to
production of indigoidine. Slightly acidic conditions (pH 6.5) favor pigment production
on plate count agar. Abundant blue pigmentation occurs on PCA, Thayer-Martin agar,
chocolate agar, blood agar, Pseudomonas F agar, and chalk agar. Violacein and
pyoverdin are not formed. Alpha-hemolytic. Aerobic. Grows at 4 ºC and 37 ºC but not at
2 ºC and 40 ºC. Grows at pH 6.2 and most strains grow at pH 8.6, but not at pH 4.0.
Grows in the presence of 1 % (w/v) NaCl, but not in 2% NaCl. Fluorescence-positive
on chalk agar (very weak).
