Phylum of bacteria
The FCB group is a superphylum of bacteria named after the main member phyla Fibrobacterota , Chlorobiota , and Bacteroidota . The members are considered to form a clade due to a number of conserved signature indels .[ 2]
Cavalier-Smith calls the equivalent grouping a phylum by the name of Sphingobacteria . It contains the classes Chlorobiota , Fibrobacterota , Bacteroidota , and Flavobacteria . However, this megaclassification is not followed by the larger scientific community.[ 3] [ 4] [ 5]
An analogous situation is seen with the PVC group/Planctobacteria .
The Bacteroidota–Chlorobiota group in brown is visible on this 2016 tree of life using ribosomal protein sequences[ 14]
