Avaliação da biodegradação dos corantes têxteis laranja Reafix, castanho Solimax, violeta Solimax e um efluente real, pelo fungo Phanerochaete chrysosporium

Abstract

The textile industries use dyes for dyeing fibers that have important characteristics for fixing the color in the fabric, but these same characteristics also demonstrate severe environmental risks if their disposal is done without proper treatment. The present study proposes to evaluate the removal of color from a real effluent and three synthetic effluents composed of Reafix orange, Solimax brown and Solimax violet dyes, based on the enzymatic action performed by the fungus P. chrysosporium. The use of this fungus proved to be suitable for this purpose, showing a significant reduction in the concentration of dyes in the medium tested. In the real effluent, despite the impaired growth of the fungus due to its chemical characteristics, a reduction in absorbance can still be observed, indicating the degradation of the dye.
