Novel biotechnologies for nitrous oxide abatement

Abstract: La temperatura del planeta ha ido aumentando a una tasa sin precedentes a partir de la segunda mitad del siglo XIX, resultando en la aceleración de los efectos del cambio climático. A día de hoy, existen evidencias irrefutables que demuestran que el ser humano es el principal responsable del atípico aumento de la temperatura del planeta. En efecto, se ha encontrado una clara correlación entre el aumento de la concentración atmosférica de gases de efecto invernadero (GEI), los cuales tienen la capacidad de rete… Show more

“…Biological nitrogen-removal systems, including the activated sludge system (0.06%), nitrification (2.7-9%) [11], partial nitrification (nitritation), anaerobic ammonia oxidation (anammox), nitritation-anammox procedure (1.3-2.2%) [12], nitrifier denitrification, denitrification (0.6-1.9%) [13] and nitrification-denitrification process (1.9-8.5%) [14], have been identified as potential sources of N 2 O emission [15]. Nearly 70% of these emissions are attributed to the NH 4 + -N oxidation process, resulting in a nitrogen conversion of 27% with equivalent to 600 parts per million by volume (ppmv) [16]. In the family of microbes involved in the nitrogen cycle, aerobic ammonia-oxidizing bacteria (aerAOB) have been found to release higher amounts of N 2 O compared to aerobic ammonia-oxidizing archaea (aerAOA) and comammox bacteria [17].…”
