Gram-negative rods, 0.3-0.6 x 0.8-1.6 μm. Non-sporulating. Motile by peritrichous
flagella.
flagella.
Colonies on 100-fold diluted NB agar are circular, entire, convex, opaque and white.
Growth is observed in NB and 10-fold and 100-fold diluted NB at 27 and 30 ºC, but not
at 41 ºC. Aerobic. Chemolithoautotrophic growth occurs in the presence of hydrogen,
oxygen and carbon dioxide.
