The metagenomic basis of anammox metabolism in Candidatus 'Brocadia fulgida'.

Anammox (anaerobic ammonium oxidation) coupled to nitrite reduction is an important step in the nitrogen cycle and has been recognized as an important sink for fixed nitrogen in the ocean. Still little is known about the genomic blueprint of different anammox species. In the present article, we discuss the important genes of anammox metabolism in Candidatus 'Brocadia fulgida' that were retrieved via a metagenomic approach.
