Figure 6. Neighbor-joining tree showing the phylogenetic relationship among the top 50 OTUs in this study (red) with known cellulose degraders (blue) and OTUs identified in the giant panda (green).

Different phyla were shaded by different colors: green, Firmicutes; purple, Actinobacteria; orange, Bacteroidetes; blue, Proteobacteria. All bootstrap values > 50% were shown on the tree.
