Gram-negative, straight rods, 0.7-0.8 x 2.0-4.0 μm. Motile. Non-spore-forming.
Colonies on TSA are translucent, beige, non-pigmented, round, convex and smooth
with entire margins at 28 ºC within 3 days. Grows 22 ºC and 36 ºC, but not at 41 ºC.
Facultatively anaerobic.

Isolated from the gut of adult bark beetle (Ips typographus) collected from the bark of Norway spruce (Picea abies) in Lithuania.
Resistant to myrcene (7-methyl-3-methylene-1.6-octadiene, C10H16, known as the defensive compound of Norway spruce), and is
capable of surviving at a concentration as high as 10 μl /ml myrcene in TSB.
