Phyla mainly responsible for cellulose degradation in the anaerobic digesters: Phylogenetic distribution of phylum level of Homology to Peptide (HotPep)-predicted cellulytic enzymes in the five phyla with highest number of HotPep-predicted cellulytic enzymes. Enzyme Commission (EC) numbers are on the left and the phyla are on the right side. The outer ring designates the relative abundance of genes from a given phylum (left) and the relative abundance of a given cellulytic enzyme (right); the inner ring designates the total number of genes encoding for a given cellulytic enzyme (left) and the total number of cellulytic enzyme associated with the given phylum. The width of the bars between a given phylum and a given cellulytic enzyme indicates their relative abundance to the other phyla mentioned
