ResumoThe production and consumption of mushrooms has increased, resulting in large amount of residue from cultivation, called spent mushroom compost (SMC). This study aimed the active enzymes recovery from SMC of Hypsizygus marmoreus, Flammulina velutipes, Pleurotus eryngii, Lentinula edodes, Pleurotus ostreatus and Pleurotus sp. Results indicated that it was possible to recover different types of enzymes (exocellulase, endocellulase, total cellulase, β-glucosidase, dextranase, amylase and laccase) from the SMCs, demonstrating the diversity of enzymatic activity in these compounds depending on the mushroom. It was also observed that the extract obtained from Pleurotus sp, a mushroom originated from the crossbreeding of two types of Pleurotus, had a different enzymatic profile, with a greater decolorizing capacity than other fungus tested. Thus, the results indicate that depending on the desired enzymatic activity, and therefore the final aim, a specific type of Basidiomycete SMC should be selected, since each one presents a distinct enzymatic profile.
