Achromobacter kerstersii Vandamme et al. 2016.
Gram-negative rods, 0.4-0.7 x 0.9-1.5 µm. Motile.
Colonies are low convex, translucent and non-pigmented, with smooth margins and
1-1.5 mm in diameter after 48h incubation on trypticase soy agar at 28 ºC. Grows on,
blood agar, Drigalsky agar, but not on acetamide. Variable growth on cetrimide agar.
Nonhaemolytic. Can grow in 3% NaCl and 4.5% NaCl (most strains), not in 6% NaCl.
No growth at 42 ºC. No fluorescence on King’s B medium.
Isolated from soil samples.
