of a single polar flagellum.
of a single polar flagellum.
Colonies are circular and colourless. Growth occurs in media supplemented with
3.5% NaCl, but not in media with salinity higher than 9% at pH 10. Growth occurs at
4-30 ºC, but no growth is observed at 40 ºC or higher. Can grow on MacConkey agar.
Can degrade poly(3-hydroxybutyrate).
