Gram-negative rods, 3.4 x 5.4 µm. Motile by one polar flagellum. Non-spore-forming.
Colonies on TSA agar are circular, flat, opaque, mucoid, beige coloured, with entire
edges and approximately 1-3 mm in diameter after incubation at 22 C for 2 days. No
pigment is produced when grown in King A or B mediums. Grows at 6-36 ºC, pH 6-10
and in the presence of 0-3% NaCl. Aerobic.

Isolated from rocks surfaces and water samples from a karstic cave, Mallorca (Balearic Island), Spain.
