Anaerobic ammonium oxidation (anammox) has become a main focus in oceanography and wastewater treatment. It is also the nitrogen cycle's major remaining biochemical enigma. Among its features, the occurrence of hydrazine as a free intermediate of catabolism, the biosynthesis of ladderane lipids and the role of cytoplasm differentiation are unique in biology. Here we use environmental genomics—the reconstruction of genomic data directly from the environment—to assemble the genome of the… Expand
Combined structural and chemical analysis of unique anammox bacteria that contain a prokaryotic organelle
The anaerobic oxidation of ammonium to dinitrogen gas (anammox) is a recently discovered pathway of the biological nitrogen cycle [1] and is currently estimated to be a major source of gaseousExpand
Biochemistry and molecular biology of anammox bacteria
TLDR
The present anammox pathway is the only one consistent with the available experimental data, thermodynamically and biochemically feasible, and consistent with Ockham’s razor: it invokes minimum biochemical novelty and requires the fewest number of biochemical reactions. Expand
Hydrazine Synthase, a Unique Phylomarker with Which To Study the Presence and Biodiversity of Anammox Bacteria
TLDR
Developed PCR primer sets targeting a subunit of the hydrazine synthase (hzsA), which represents a unique phylogenetic marker for anammox bacteria, were able to retrieve hzsA gene sequences fromanammox enrichment cultures, full-scale anamm ox wastewater treatment systems, and a variety of freshwater and marine environmental samples. Expand
The ultrastructure of the compartmentalized anaerobic ammonium-oxidizing bacteria is linked to their energy metabolism.
TLDR
The present review summarizes the knowledge about the ultrastructure of anammox cells and the connection between theAnammoxosome and the energy metabolism of the cell and suggests the unusual subcellular organization may well be essential for the lifestyle of anamsox bacteria. Expand
The Metabolism of Anammox
TLDR
Anaerobic ammonium-oxidizing (anammox) bacteria derive their energy for growth from the conversion of ammonium and nitrite into dinitrogen gas by a newly discovered and specialized group of micro-organisms, the anammox bacteria. Expand
Nitrifier genomics and evolution of the nitrogen cycle.
TLDR
The natural history of the nitrogen-cycle has been redrawn with emphasis on the early roles of incomplete denitrification and ammonification as driving forces for emergence of ANAMMOX as the foundation for a complete nitrogen cycle, and concluding with emergence of nitrification in the oxic era. Expand
Metabolism and Genomics of Nitrite-Oxidizing Bacteria: Emphasis on Studies of Pure Cultures and of Nitrobacter Species
TLDR
The genome analysis of Nitrobacter has provided some new and confirmatory insights into the biology of this genus, and several genes encoding for enzymes that facilitate metabolism of pyruvate, acetate, and glycerol were identified. Expand
The impact of genome analyses on our understanding of ammonia-oxidizing bacteria.
TLDR
The core metabolic module of aerobic ammonia oxidation, the extraction of electrons from hydroxylamine to generate proton-motive force and reductant, has evolutionary roots in the denitrification inventory of anaerobic sulfur-dependent bacteria. Expand
Autotrophic and mixotrophic metabolism of an anammox bacterium revealed by in vivo 13C and 2H metabolic network mapping
TLDR
The central carbon metabolism of the anammox bacterium Candidatus ‘Kuenenia stuttgartiensis’ is experimentally resolved using time-series 13C and 2H isotope tracing, metabolomics, and isotopically nonstationary metabolic flux analysis, and several instances where genomic predictions are not supported by in vivo metabolic fluxes are revealed. Expand
A Nitrospira metagenome illuminates the physiology and evolution of globally important nitrite-oxidizing bacteria
TLDR
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.

TLDR
The complete genome sequence of Geobacter sulfurreducens, a δ-proteobacterium, reveals unsuspected capabilities, including evidence of aerobic metabolism, one-carbon and complex carbon metabolism, motility, and chemotactic behavior, which suggest the organism has the potential for use in bioremediation of radioactive metals and in the generation of electricity.

TLDR
Phylogenetic analysis of all relevant markers clearly affiliates the Planctomycetales to the domain Bacteria as a distinct phylum, but a deepest branching is not supported by the authors' analyses. Expand

The purpose of this article is to highlight the diverse physiological features of this model acetogen and to examine some of the consequences of its metabolic capabilities. Expand

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.

Phylogeny: A non-hyperthermophilic ancestor for Bacteria
TLDR
It is found that hyperthermophilic bacteria (such as Aquificales and Thermotogales) do not emerge first, suggesting that the Bacteria had a non-hypertherMophilic ancestor, and it seems that Planctomycetales, a phylum with numerous peculiarities, could be the first emerging bacterial group. Expand
Anaerobic oxidation of methane and ammonium.
TLDR
Because both anaerobic methane and ammonium oxidation have been separately and excellently reviewed elsewhere, the added value of reviewing these two processes in one place is explored. Expand

The phylum Planctomycetes of the domain Bacteria consists of budding, peptidoglycan-less organisms important for understanding the origins of complex cell organization, in which the nucleoid is enveloped in two membranes to form a nuclear body analogous to the structure of a eukaryotic nucleus.
