ABSTRACT
Natural and artificial wetlands have demonstrated to be efficient systems for the biological degradation of pesticides. A particular example for the biological elimination of an emerging pollutant would be the degradation of the chemical herbicide atrazine using a microbial consortium isolated within the natural wetlands represented by the Xochimilco channels. An alternative option through which most compounds are transformed into simpler chemical molecules with variable toxicity is the microbiological degradation using bacteria, actinomycetes, yeasts, microalgae, fungi, protozoa, among others, since these microorganisms use these pollutants as an energy source. To enhance the electricity production, it is necessary to investigate new parameters that would favor the redox required conditions besides improving the electrogenic microorganisms environment for the transferring of electrons from the anode to the cathode. Solid phase extraction is one of the most widely known techniques in the environmental labs particularly for aqueous samples, concentrating and cleaning the extracts before its analysis.
