Ten years ago, an anaerobic ammonium oxidation (‘anammox’) process was discovered in
a denitrifying pilot plant reactor. From this system, a highly enriched microbial community …

Many countries strive to reduce the emissions of nitrogen compounds (ammonia, nitrate, NO
x ) to the surface waters and the atmosphere. Since mainstream domestic wastewater …

Planctomycetes form a distinct phylum of the domain Bacteria and possess unusual features
such as intracellular compartmentalization and a lack of peptidoglycan in their cell walls. …

With the increased use of chemical fertilizers in agriculture, many densely populated countries
face environmental problems associated with high ammonia emissions. The process of …

The bacteria that mediate the anaerobic oxidation of ammonium (anammox) are detected
worldwide in natural and man-made ecosystems, and contribute up to 50% to the loss of …

Anaerobic ammonium oxidation (anammox) is both a promising process in wastewater
treatment and a long overlooked microbial physiology that can contribute significantly to …

The organisation of cells of the planctomycete species Pirellula marina, Isosphaera pallida,
Gemmata obscuriglobus, Planctomyces maris and "Candidatus Brocadia anammoxidans" …

Anammox bacteria belong to the phylum Planctomycetes and perform anaerobic ammonium
oxidation (anammox); they oxidize ammonium with nitrite as the electron acceptor to yield …

The phylum Planctomycetes of the domain Bacteria consists of budding, peptidoglycan-less
organisms important for understanding the origins of complex cell organization. Their …

The planctomycetes are an unusual but widely distributed group of budding bacteria which
are proving to be of increasing relevance to at least three major areas of research in …
