Figure 5 | OEUs corresponding to sulfate reduction do not have
metabolically identical OTUs. The three OEUs with profiles corresponding
to sulfate reduction in the model are shown (the black lines are OTUs within
each OEU; the red lines are the relative rate of sulfate reduction predicted by
the model). The rows in each OEU correspond to each of that OEU’s
member OTUs. Of these three OEUs, the single-cell assay determined that
two OEUs contained member OTUs that carry the diagnostic enzyme for
sulfate reduction. The relative abundance in the second column is percent of
the control non-specific 16S-barcode fusion library corresponding to each
OTU sequence. The third column indicates whether a fusion product was
identified in the dsrB-16S gene fusion library (+/−). The fourth column
indicates phylum level classification for each OTU, even if the OTU could be
classified at a lower taxonomic rank.
