The distribution and genetic diversity of the functional microorganisms in five lab-scale CANON reactors have been investigated by using some molecular biology methods. Nitrosomonas-like aerobic ammonium oxidizing bacteria (AerAOB) and Candidatus Brocadia-related anaerobic ammonium oxidizing bacteria (AnAOB) were detected as predominant functional microbes in the five reactors while Nitrobacter-like nitrite oxidizing bacteria (NOB) existed only in the systems operated at ambient temperature. Communities of AerAOB and AnAOB were almost similar among the five reactors while the distribution of the functional microbes was either scattered or densely packed. Meanwhile, this study has demonstrated the feasibility of starting up CANON by inoculating conventional activated sludge in low ammonium content at ambient temperature. not specified 289.1 CC-BY-3.0 Creative Commons Attribution 3.0 Unported https://creativecommons.org/licenses/by/3.0/ Picture of a FISH analysis of biofilm samples from five CANON reactors. Left: Optical photomicrographs; Right: FISH micrographs: hybridization of biomass with Cy3-labelled NOS190 (red, targeting AerAOB), AMCA-labelled AMX368 (blue, targeting AnAOB) and HEX-labelled NIT3 (green, targeting Nitrobacter). AerAOB appears purple because of the overlapping of red and blue backgrounds.
