Sphingobacteria (phylum)
Sphingobacteria is a division (phylum), created by Cavalier-Smith, which contains the classes Chlorobea, Fibrobacteres, Bacteroidetes and Flavobacteria.
It is however not followed by the larger scientific community. The group is commonly referred to as the "FCB group" with the rank of superphylum and the subdivisions are of the rank phylum and are referred to as:
- Chlorobi (Chlorobea in Cavalier-Smith megaclassification)
- Bacteroidetes, which differs from Cavalier-Smith megaclassification as it is composed of the classes Bacteroidia (equivalent to Cavalier-Smith's Bacteroidetes), Cytophagia and Flavobacteria and Sphingobacteria
- Fibrobacteres
An analogous situation is seen with the PVC group/Planctobacteria.
