TL;DR: The presented 16S rRNA and amoA and AmoA sequence data from all recognized AOB species significantly extend the currently used molecular classification schemes for AOB and now provide a more robust phylogenetic framework for molecular diversity inventories of AOB.

TL;DR: The rRNA approach was used to investigate the abundance of other well-known nitrite-oxidizing bacterial genera and found that Nitrospira-like bacteria were present in significant numbers and frequently occurred in coaggregated microcolonies with N. mobilis.

TL;DR: A new microscopic method for simultaneously determining in situ the identities, activities, and specific substrate uptake profiles of individual bacterial cells within complex microbial communities was developed by combining fluorescent in situ hybridization performed with rRNA-targeted oligonucleotide probes and microautoradiography.

TL;DR: The microbial community structure of a trickling filter biofilm with a high anaerobic ammonium oxidation activity is investigated and it is revealed that ammonia-oxidizing bacteria of the beta-subclass of Proteobacteria were also present, albeit in significant smaller amounts, within the anoxic biofilm.

TL;DR: This study provides the first encompassing, high-resolution insight into the in situ composition of the microbial community present in a full-scale, industrial wastewater treatment plant.
