The use of solid residues from Pleurotus ostreatus mushroom production to degrade different dyes was investigated. The solid residue was composed by hemicellulose and cellulose (52.81%), acid insoluble lignin (25.42%), chitin (6.5%) and water extractives (14.82%). Laccase and manganese peroxidase activities were 0.5 Ug-1 and 12 mUg-1 respectively. Decolorization percentages achieved were up to 100 for Azure B and Indigo Carmine, 74.5 for Malachite Green (MG), and zero for Xylidine. Highest adsorption was observed with MG (95%). Therefore, solid residue from P. ostreatus cultivation was presented as an alternative for studies focused on bioremediation of water and wastewater.
