- Abstract
Pesticides have contributed to improve the productivity and quality of agricultural production however, but their inadequate use can pollute the environment. Biobeds are bioremediation systems used to prevent specific contamination with agrochemicals during the filling process of fumigation equipment. In this work, a selection of strains of white rot fungi was made for the design of biomixtures with agricultural residues from the province of Córdoba. The enzymatic activity of the fungi was evaluated against four pesticides commonly used in the productive systems of the central region of Argentina. Trametes villosa CCC32 was the strain that showed the best enzymatic activity and was selected for the development of the biomixture. Laboratory scale biobeds were developed with the selected strain and sunflower husk as the lignocellulosic substrate. The enzymatic activity of phenoloxidases in the biobeds was determined. The bioassays with extracts of the biomixtures showed after 240 days of treatment a germination rate of 60%. The results obtained in the enzymatic measurements and the phytotoxic evaluation carried out in biobeds at laboratory scale are promising and suggest a great potential of biomixtures for the development of real scale biobeds.
