Abstract (EN): The new possibilities of applying enzymes for organic waste treatment is studied. The reaction conditions for the degradation of phenol in aqueous and non-aqueous media (with ionic liquids) by biocatalysis using a commercial laccase were examined. Laccase from T. versicolor showed a higher capacity of phenol degradation and also a higher rate of reaction than laccase from Aspergillus. Better phenol degradation was obtained for pH 6. To improve the oxidation of phenol by laccase, the presence of enzyme mediators is required. The ABTS mediator promoted the highest phenol degradation (91%), although presenting a slight difference when compared to the others mediators. This is an abstract of a paper presented at the CHISA 2012 - 20th International Congress of Chemical and Process Engineering and PRES 2012 - 15th Conference PRES (Prague, Czech Republic 8/25-29/2012).
