Resumen
Was evaluated the application of immobilized biomass of Phanerochaete chrysosporium in removal of Congo Red (20 mg/L) in sequencing batch reactor, in cycles of 48 h, in the presence of glucose, added to the medium at concentrations of 5 g/L (Stage I) and 1 g/L (Step II). Removals were recorded averages 86% and 97% dye, respectively, in Stages I and II in relation to chromophore; and mean removal of organic matter from 56% (Stage I) and 76% (Stage II). There was formation of by-products and difficulty of rupture of the dye molecule, particularly, to a wavelength related to benzene, checking it if still greater production of manganese peroxidase enzyme in the presence of low concentration of glucose (1 g/L). Was obtained mean removal of 83% and 65% for ammonia and 74%, and 56% for nitrate, respective steps I and II. The fungi population on reactor was predominated in biofilm during the experiment, and was shown to be viable as the removal of color, being necessary the study of strategies that promote greater mineralization of the dye.Key Words: co-substrate, ligninolitc enzymes, enzymatic inhibition, Phanerochaete chrysosporium, sequencingbatch reactor, congo red.
