Resumen
Advances in biotechnology have shown that the degradation of toxic and recalcitrant xenobiotics is a viable alternative for pollution control. A critical analysis is offered of the applicability of modified strains in the two related fields of environmental engineering wastewater treatment and bioremediation of soils and aquifers. There is a variety of products on the market for bioremediation or intensification of wastewater treatment. The application of these products should be preceded by detailed feasibility studies. The systems where they are used must offer precise control over the biodegradation process. An alternative to the purchase of commercially available strains is the isolation, identification and evaluation of indigenous microorganisms, and the adaptation of mixed cultures. Batch or lot processes that reproduce the physico-chemical parameters of the system may be used to acclimate the organisms. The microorganism best adapted to the degradation of a given pollutant is isolated from an environment in which the toxic is present.
