ABSTRACT
The aim of this work was to evaluate the performance of the fungus Lentinula edodes UEC 2019 in the treatment of an effluent derived from a wood laminate manufacturing process. The factorial design methodology was employed to verify the influence of the source of nitrogen, co-substratum and treatment time variables on the color and total phenols reduction. Assays were conducted in Erlenmeyer flasks and bench bioreactor and the obtained results showed that the best conditions for the effluent remediation were observed when using the effluent itself as the nitrogen source (1g/L) and glucose (79 g/L) as co-substratum (glucose) during a treatment period of 30 days. It was possible the remove 92% phenol, 97% color and reduce the COD in the bioreactor by 99% while controlling the temperature, pH and feeding. These results demonstrate that the fungus was able to use the effluent components as substrate and that it has potential for use in wood lamination effluent remediation.
