Negative results for amylase, DNase, beta-glucosidase, gelatinase, lysine decarboxylase, tryptophanase and urease.
No assimilation of melibiose, sucrose, trehalose, turanose, D-tagatose, methanol and methylamine.

Gram-negative rods, 1.0 x 2-3 μm. Non-motile. Non-sporeforming.
Colonies on R-2A agar are white to cream with a smooth edge. Grows at 4-40 ºC
(optimally at 30-37 ºC), at pH 3.5-8.3 (optimum pH 5-6) and with salt concentrations of
up to 2.7% NaCl (optimum 0-1.0%). Tolerates at least 0.5 mM AsV or AsIII and 10%
(w/v) lactose, but not cetrimide (0.03%, w/v). Slow growth occurs lithoautotrophically
with CO2 as sole C source, O2 as electron acceptor and thiosulfate or nitrite as
electron donors; sulfite, sulfide or AsIII do not support lithotrophic growth. N2 can be
used as sole N source.
