Gram-negative straight rods, 0.40-0.45 x 1.3-1.8 µm, occurring singly and in pairs.
Motile by two polar flagella. Non-spore-forming.
Motile by two polar flagella. Non-spore-forming.
After 48 h of incubation at 25 ºC on LB agar, colonies are 1.5-2.5 mm in diameter,
greenish and mucoid with irregular edges. Growth occurs at 4-35 ºC, optimally at 28
ºC, and at pH 4.0-9.5. Can grow in the presence of 0-6% (w/v) NaCl. Grow on NA
containing 1% (w/v) 2,3,5-triphenyltetrazolium chloride, with slightly red to pink
colonies. Green fluorescent pigments are produced on King’s A and B media. Aerobic.
