Combined sample phylogenetic content. The proposed methodology was applied to the reads obtained from six samples and results were aggregated in a single tree. Branch widths indicate the proportion of reads assigned down those branches in the phylogeny. Branches fading into white represent reads that are resolution limited due to similarity among multiple sub-branches in the phylogeny. Branches fading into black represent reads that do not have full-length homology with any known 16S sequence.
