Technical Abstract: Anaerobic ammonium oxidation (ANAMMOX) is a promising process in the nitrogen cycle, especially in wastewater treatment. Under anoxic conditions the ammonium is oxidized to nitrogen gas by a group of bacteria belonging to phylum Planctomycetes. These organisms have been detected in a variety of environments. Aiming to analyze the bacterial community in a sludge reactor maintained in a laboratory scale, samples were submitted to DNA amplification, cloning, sequencing and phylogenetic analysis. Seventeen clones were obtained and three of them presented identity with Anammox genus and were related to Planctomycete KSU-1 and Candidatus Jettenia asiatica. The dominant bacteria genus in the reactor was clustered with Janthinobacteium.
