The Flavobacteriales form an order within the division of the Bacteroidetes . It is the only order of the Flavobacteriia class .
Appearance
The gram test is negative. The cells are rod-shaped, some species form filaments from several cells. The latter includes z. B. the species Fluviicola taffensis placed among the Cryomorphaceae . Spores are not formed. Species of the families Cryomorphaceae and Flavobacteriaceae are aerobic or facultatively anaerobic , flagella are not present. Some species can move by gliding ("gliding motility"). The species Blattabacterium cuenoti forms a symbiosis with cockroaches and the termite species Mastotermes darwiniensis . Blattabacterium cuenoti was found exclusively within these insects and is vital for the insects.
metabolism
All species are chemo-organotrophic , metabolism is either respiration or, as in some species of the Flavobacteriaceae, fermentation .
Systematics
The following families belong to the order Flavobacteriales:
- Blattabacteriaceae
- Crocinitomicaceae
- Cryomorphaceae
- Flavobacteriaceae
- Ichthyobacteriaceae
