SANCHEZ, Jaime  y  SANABRIA, Janeth. Microbial metabolisms over advanced processes for Nitrogen removal, a prospective review. Rev. colomb. biotecnol [online]. 2009, vol.11, n.1, pp.114-124. ISSN 0123-3475.

Advanced processes for nitrogen removal are intimately related to the microbial community metabolisms that take part in the transformations. For the design, optimization or improvement of domestic waste water treatment systems, engineers and microbiologists working together, have managed to implemented suitable tertiary reactors for the development of these communities, improving the efficiency of nutrient removal. This article presents a revision of the bacterial activity and its application in treatment systems. The article begins by giving an explanation about the influence of microorganism and human activity on the global nitrogen cycle. Then, it analyzes the particular processes in which the microorganisms take part. New evidence of related metabolisms are classified and included. Some of the processes of wastewater tertiary treatment, successfully developed over the last decades, are described as examples.

Palabras clave : nitrogen compounds removal; advance treatment systems; nitrification; nitrafication; denitrification; denitrafication; anammox; nitrogen.
