polar flagellum. Poly-beta-hydroxybutyrate is not accumulated.
On Luria Bertani agar plates, produces smooth white colonies with regular edges,
1-2 mm in diameter after 72 hours incubation at 30 ºC, non-pigmented and slightly
raised in the centre. Moderately halophilic, growing in 0–8% NaCl broth (optimum 1-
3%). Grows at 10-45 ºC (optimum 25-30 ºC), but not at 4 or 50 ºC.
