Abstract (English): The dumping of large polluted domestic wastewater is one of the main problems associated to the inadequate use of hydric resources by humans. Different physical and chemical technologies have been applied for water treatment. Nevertheless the use of biological systems, in special the microorganisms, has been extensively developed in recent years due to its various advantages. In present research organic matter, nitrogen and phosphorus removal by bacterial monocultures and consortia was evaluated from simulated domestic sewage. Three bacteria strains were used: Bacillus subtilis (AL-25), Bacillus cereus (AL-30) and Micrococcus sp. (AL-138). Their capacities were determined for different carbon source assimilation, proteolytic and lipolytic activities, and phosphate and ammonium removal. Taking into account these previous results, four consortia were designed. The feasibility of using consortia CMB3 and CMB4 in the mixed removal of nutrients was determined in a simulated domestic wastewater with removal values higher than 88 %. The monocultures of Bacillus cereus (AL-30) and Micrococcus sp. (AL-138)presented high percentages of COD (Chemical Oxygen Demand) and phosphate removal, respectively. These values were similar or higher than those reached by the consortia; for this reason they can constitute an alternative for wastewater treatment with these pollutants. The potentialities showed by these bacterial biomasses make them attractive candidates for future application on wastewater treatment systems for the elimination of these pollutants.

Abstract (Spanish): El vertimiento de aguas residuales domésticas, con un elevado grado de contaminación, constituye uno de los principales problemas asociados al uso inadecuado de los recursos hídricos por el ser humano. Como tecnologías de tratamiento se aplican diferentes métodos físicos y químicos, sin embargo, el empleo de sistemas biológicos, especialmente de microorganismos, ha tomado auge en los últimos años por sus múltiples ventajas. Este trabajo tuvo como objetivo evaluar la remoción de materia orgánica, nitrógeno y fósforo por monocultivos y consorcios bacterianos, a través de su interacción en agua residual doméstica simulada. Se emplearon tres cepas bacterianas: Bacillus subtilis (AL-25), Bacillus cereus (AL-30) y Micrococcus sp. (AL-138). Se les determinó la capacidad para degradar diferentes fuentes de carbono, la actividad proteolítica y lipolítica, así como la remoción de amonio y fósforo. A partir de los resultados de la interacción de las cepas con los compuestos de interés se diseñaron cuatro consorcios. Los sistemas mixtos denominados CMB3 y CMB4 mostraron los resultados más integrales en cuanto a la remoción diversa de contaminantes, con valores de remoción superiores al 88 %. Los monocultivos de Bacillus cereus (AL-30) y Micrococcus sp. (AL-138) presentaron elevados porcentajes de remoción de DQO (Demanda Química de Oxígeno) y fosfato, respectivamente. Estos valores fueron similares o superiores a los alcanzados por los consorcios; por ello pueden constituir una alternativa para el tratamiento de aguas con estos contaminantes. Los resultados demuestran las potencialidades de las biomasas bacterianas empleadas para su aplicación en el tratamiento de aguas residuales con la presencia de estos compuestos.
