Features

The types of Moraxellaceae are rod - or kokkenförmig. Like all Proteobacteria, they are gram negative. They are catalase -positive. Within the family, also cold-loving ( psychrophilic ) species occur ( genus Psychrobacter ). Some species can form capsules. They are aerobic, that is, they are dependent on oxygen, and chemoheterotroph. Flagella are not usually available, but some species can dramatically propelled by an " elastic spring mechanism ". This is produced by special pili. Examples include Moraxella bovis, Moraxella nonliquefaciens and several species of Acinetobacter.
