Abstract:

Several textile and food dyeing industries discharge annually large amounts of dissolved dyes, which are disposed with minimal or no treatment. These compounds are highly toxic for both, the aquatic ecosystem and human health. It has been reported that the use of chemical, physical and biological treatment methods of colored effluents. In this study a strategy that combines a physical adsorption method and a biological process was implemented. To evaluate the red 40 dye (R40) degradation under Solid State Fermentation (SSF) conditions, nine different treatments were carried out, in which the moisture content, carbón:nitrogen ratio (C: N) and the copper sulfate concentration as Inductor (IC) were the variables. Each of these treatments was carried out with the fungal species Trametes versicolor and Pleurotus ostreatus. Corncob wastes with R40 dye after an adsorption process was used as solid support for the SSF. Moisture content of 75%, C:N ratio of 30 and IC of 0.5 mM, were the best conditions found to T. versicolor achieving a degradation percentage of 96.9%. With P. ostreatus, 81% of degradation was achieved under the best conditions, moisture content of 80%, C:N ratio of 20, and without inductor addition. The results suggest that the process of SSF with white-rot fungi is efficient for the R40 dye degradation; therefore this methodology could be implemented on a larger scale.
