Missing lithotroph identified as new planctomycete
The discovery of this missing lithotroph and its identification as a new, autotrophic member of the order Planctomycetales, one of the major distinct divisions of the Bacteria makes an important contribution to the problem of unculturability.
A microbial consortium couples anaerobic methane oxidation to denitrification
It is shown that the direct, anaerobic oxidation of methane coupled to denitrification of nitrate is possible and that the reaction presented here may make a substantial contribution to biological methane and nitrogen cycles.
Nitrite-driven anaerobic methane oxidation by oxygenic bacteria
Evidence for a fourth pathway to produce oxygen is presented, possibly of considerable geochemical and evolutionary importance, and opens up the possibility that oxygen was available to microbial metabolism before the evolution of oxygenic photosynthesis.
Anaerobic ammonium oxidation by anammox bacteria in the Black Sea
Evidence for bacteria that anaerobically oxidize ammonium with nitrite to N2 in the world's largest anoxic basin, the Black Sea is provided and anammox bacteria have been identified and directly linked to the removal of fixed inorganic nitrogen in the environment.

It is shown that in the ETSP-OMZ, anammox obtains 67% or more of NO2− from nitrate reduction, and 33% or less from aerobic ammonia oxidation, based on stable-isotope pairing experiments corroborated by functional gene expression analyses.

The results indicate that the enriched subgroup of NC10 bacteria is responsible for anaerobic methane oxidation coupled to nitrite reduction.
Candidatus "Scalindua brodae", sp. nov., Candidatus "Scalindua wagneri", sp. nov., two new species of anaerobic ammonium oxidizing bacteria.
A new genus and species of anaerobic ammonium oxidizing planctomycetes, discovered in a wastewater treatment plant treating landfill leachate in Pitsea, UK, are described, making this genus the most widespread of all anammox bacteria described so far.
Deciphering the evolution and metabolism of an anammox bacterium from a community genome
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.

It is shown that instead, the anammox process (the anaerobic oxidation of ammonium by nitrite to yield N2) is mainly responsible for nitrogen loss in the OMZ waters of one of the most productive regions of the world ocean, the Benguela upwelling system.

Evidence is presented that dissimilatory nitrate reduction to ammonium occurs in Benguela upwelling system at the same site where anammox bacteria were previously detected, indicating that anamm Oxidizing bacteria could be mediating Dissimilatory Nitrate reductionto ammonium in natural ecosystems.
