FISH images of sludge from reactor enriched in Accumulibacter clade IIA (R2). Images in panels (A) and (B) were collected in the same field, and panels (C) and (D) were collected in the same field. Cells in panels (B) and (D) were hybridized with PAOMIX probes and labeled cells are therefore members of the Accumulibacter lineage (Crocetti et al., 2000). Labeled cells (green) in panel (A) are hybridized with Acc-II-444, and labeled cells (green) in panel (C) are hybridized with Acc-I-444. Comparison of panels (C) and (D) demonstrates the heterogeneity within the Accumulibacter community, since many cells identified as Accumulibacter by PAOMIX in (D) are not hybridized with Acc-I-444 in (C).
