Ammonia oxidising archaea are among the most abundant living organisms on Earth and
key microbial players in the global nitrogen cycle. They carry out oxidation of ammonia to …

Nitrite is one of the players in the broad nitrogen biogeochemical cycle. This nitrogen oxo-
anion is involved in key pathways crucial to life on Earth and to the planetary “recycling” of …

Nitrospira are barely studied and mostly uncultured nitrite-oxidizing bacteria, which are,
according to molecular data, among the most diverse and widespread nitrifiers in natural …

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

Numerous past studies have shown members of the genus Nitrospira to be the predominant
nitrite-oxidizing bacteria (NOB) in nitrifying wastewater treatment plants (WWTPs). Only …

In the United States anthropogenic activities are mainly responsible for the wide spread
perchlorate contamination of drinking water, surface water, groundwater, and soil. Even at …

The recent discovery of complete ammonia oxidizers (comammox) contradicts the paradigm
that chemolithoautotrophic nitrification is always catalyzed by two different microorganisms …

The anaerobic/anoxic/oxic (A2O) process is globally one of the widely used biological
sewage treatment processes. This is the first report of a metagenomic analysis using …

Nitrite-oxidizing bacteria (NOB) are ubiquitous and abundant microorganisms that play key
roles in global nitrogen and carbon biogeochemical cycling. Despite recent advances in …

Nitric oxide (NO) and nitrous oxide (N2O) are among nature's most powerful electron
acceptors. In recent years it became clear that microorganisms can take advantage of the …
