Enzymatic biobleaching of two recalcitrant paper dyes with horseradish and soybean peroxidase.
A stilbene dye (Direct Yellow 11) and a methine dye, Basazol 46L, recalcitrant to common chemical bleaches, were treated with horseradish and soybean peroxidases. Both enzymes were effective at chromophore removal. When compared to laccase in combination with a mediator (ABTS), soybean peroxidase was more effective at oxidative dye removal, especially for the methine dye.
