Distribution of operational taxonomic units (OTUs) of less than 97% sequence similarity in 16S rRNA gene extracted from MEC reactors. DNA extracts of 0.01, 0.1, 1, 10, and 25% were pooled prior to pyrosequencing. Less than 10% abudant OTUs were summarized as others (white bars). Archaea (top) and Bacteria (bottom) and were targeted. Reactors were inoculated with bog sediment (left) or AD sludge seed. Gp, group.
