Abstract

The research was done to evaluate phenol biodregadation capacity in Guarango(Caesalpina spinosa) tannic extract phenols and in indigo carmine, orange II and red phenols, common residues in the textile industry. Two types of fungi were used, white-rot Trametes versicolor fungus and the filamentous Aspergillus niger. Biological treatments were applied in triplicate trough the spectrophotometric UV method for 15 days. When applying the Trametes versicolor fungis to the tannic extract, there was 69.45% degradation, and a 100% discoloration in the indigo carmine. When applying Aspergillus niger fungus to the tannic extract and orange II dye, there was a 63.45% and 32.78% degradatión, respectively. There was a discoloration no greater than 26% when applying Trametes versicolor and Aspergillus niger to the red phenol. The fungi applied during the biological treatement presented tolerance to both the tannic extract composition as well as the concentration of each dye used, verified through growing kinetics of each fungus.
