CARDONA, SANTIAGO  and  SUAREZ, EDGAR. BIODEGRADATION PATHWAY PREDICTION OF POPS (PERSISTENT ORGANIC POLLUTANTS) AND BIOBARRIER TREATMENT. Dyna rev.fac.nac.minas [online]. 2010, vol.77, n.163, pp.115-123. ISSN 0012-7353.

In this paper, the biodegradation pathway of Dieldrin is simulated using an expert system. This insecticide is included in the Stockholm Convention, signed and ratified by Colombian government in 2008, and it is considered one of the most harmful human-made compounds. For this model contaminant a complete metabolic biodegradation sequence was built and a simulation-based strategy was formulated for its biodegradation in a practical case. According to the simulated metabolic pathway, a sequential aerobic-anaerobic-aerobic reactor would be the best choice to achieve complete biodegradation. Using these results, the authors propose an innovative system for the biological treatment of POPs; this system was called Bio-Reactive Permeable Barrier (BioBarrier). In this work a description of the main and fundamentals aspects of BioBarrier system is also included, showing a new and potential possibility for the bio-treatment of hazardous pollutants.
