Old synonym: Burkholderia terrestris Vandamme et al. 2013.
Gram-negative rods with rounded ends, 0.7 x 1.6-2.2 μm, occuring singly or in pairs.
Non-motile. Non-spore-forming.
After 48 h of incubation on trypticase soy agar at 28 ºC, colonies are beige, smooth,
shiny, non-translucent, round, irregular in shape with entire edges, ~ 1-1.5 mm in
diameter. Grows on MacConkey agar. Growth occurs at 15-30 ºC and at pH 6-7. No
growth at 4, 37 or 45 ºC. Grows in1% and 2% (weakly) NaCl. Aerobic.
Isolated from bulk soil collected from a long-term arable field under maize monoculture in the Netherlands.
