Anaerobic ammonium oxidation (anammox) bacteria, which were discovered in waste-water
sludge in the early 1990s, have the unique metabolic ability to combine ammonium and …

The ribosomal-RNA (rRNA) approach to microbial evolution and ecology has become an
integral part of environmental microbiology. Based on the patchy conservation of rRNA …

The marine nitrogen cycle is perhaps the most complex and therefore the most fascinating
among all biogeochemical cycles in the sea. As a limiting element for biological productivity …

Anaerobic ammonium oxidizing (anammox) bacteria are detected in many natural
ecosystems and wastewater treatment plants worldwide. This study describes the …

Nitrification plays an important role in marine biogeochemistry, yet efforts to link this process
to the microorganisms that mediate it are surprisingly limited. In particular, ammonia …

This special issue highlights several recent discoveries in the microbial nitrogen cycle
including the diversity of nitrogen‐fixing bacteria in special habitats, distribution and …

The anaerobic oxidation of ammonium (anammox) contributes significantly to the global loss
of fixed nitrogen and is carried out by a deep branching monophyletic group of bacteria …

Nitrification is the process whereby ammonium (NH4 þ) is oxidized to nitrite (NO2 À) and
then to nitrate (NO3 À). It thus links the most oxidized and most reduced components of the …

Microbiological investigation of anaerobic ammonium oxidizing (anammox) bacteria has
until now been restricted to wastewater species. The present study describes the enrichment …

We performed incubation experiments with 15N‐labeled nitrogen compounds to investigate
the vertical distribution of pathways of N2 production through the suboxic zone of the central …
