TL;DR: Two supplementary versions of probe EUB338 are designed and evaluated for in situ detection of most of those phyla not detected with this probe, which should allow a more accurate quantification of members of the domain Bacteria in future molecular ecological studies.

TL;DR: The discovery and cultivation of a completely nitrifying bacterium from the genus Nitrospira, a globally distributed group of nitrite oxidizers, and the genome of this chemolithoautotrophic organism encodes the pathways both for ammonia and nitrite oxidation.

TL;DR: This work uses environmental genomics—the reconstruction of genomic data directly from the environment—to assemble the genome of the uncultured anammox bacterium Kuenenia stuttgartiensis from a complex bioreactor community, and identifies candidate genes responsible for ladderane biosynthesis and biological hydrazine metabolism.

TL;DR: Two 16S rRNA-directed oligonucleotide probes specific for the phylum and genus Nitrospira were developed and evaluated for suitability for fluorescence in situ hybridization (FISH) and used to investigate the in situ architecture of cell aggregates of Nitro Spira-like nitrite oxidizers in wastewater treatment plants.

TL;DR: Comparison genomic analyses indicate functionally significant lateral gene-transfer events between the genus Nitrospira and anaerobic ammonium-oxidizing planctomycetes, which share highly similar forms of NXR and other proteins reflecting that two key processes of the nitrogen cycle are evolutionarily connected.
