Resumo: The direct application of Agaricus bispora mushroom was evaluated for decolorization of a synthetic mixture of reactive dyes. The effects of particle size (0.5 or 1.0 cm cubes and triturated mushroom), mushroom mass (10, 20, 40, 60 or 80 g in 250 mL of solution) and different mushroom tissue treatments were analyzed regarding color removal efficiency of dyes Reactive Yellow 37, Reactive Black 5 and Reactive Red in a synthetic solution of 13.3 mg L-1 concentration of each dye. The best results were found with larger superficial contact area between mushroom particle (triturated mushroom) and colored effluent under continuous aeration. Acetone addition during mushroom trituration process followed by a freezing step contributed to decolorization improvement, leading to best results: 73% after 6h, with 20 g of biocatalyst 250 mL-1 of effluent. The use of different mushroom batches and brands resulted in different enzymatic activities and similar levels of color removal, such result confirmed that decolorization does not have any direct relation with enzyme activity.

Avaliou-se o efeito da granulometria das partículas (cubos de 0,5 ou 1,0 cm e cogumelos moídos), da massa de cogumelos (10, 20, 40, 60 ou 80 g em 250 mL de solução) e de diferentes formas de tratamento do cogumelo sobre a remoção de cor de uma solução sintética dos corantes Reactive Yellow 37, Reactive Black 5 e Reactive Red na concentração de 13,3 mg L-1 cada corante. Os melhores resultados foram obtidos para maiores áreas superficiais de contato do cogumelo (cogumelo moído) com o efluente colorido e sob aeração contínua. A adição de acetona durante o processo de moagem, seguido de congelamento, contribuiu para o aumento da remoção de cor, obtendo-se os melhores resultados: 73% após 6h, com 20 g de biocatalisador 250 mL-1 de efluente. A utilização de diferentes lotes e marcas de cogumelo levou à obtenção de diferentes atividades enzimáticas, mas percentuais similares de remoção de cor, indicando que a remoção de cor não possui relação direta com a atividade enzimática.Universidade Estadual De Maringá2010-11-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontratamento de efluenteapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/633910.4025/actascitechnol.v32i3.6339Acta Scientiarum.
