Resumo
If not properly and efficiently treated, wastes produced by the chemical industry can
contaminate the environment. Using fungi able to degrade organic compounds (e.g. phenol)
seems to be a prominent method to treat pharmaceutical wastewaters, in particular, the white-
rot fungus. The aim of this work was to treat pharmaceutical effluent by the Pycnoporus
sanguineus fungus. Three effluent samples were collected in a pharmaceutical industry. The
production of enzymes such as laccase and manganese peroxidase was determined. Their
production increased throughout the treatment with the P. sanguineus fungus, reaching
maximum concentration of 4.48 U.mL -1 (Effluent 1), 8.16 U.mL -1 (Effluent 2), 2.8 U.mL -1
(Effluent 3) and 0.03 Abs.min -1 (Effluent 2), respectively, during 96 hours of biological
treatment. Genotoxic effects of the raw and treated effluents were also investigated using the
in vivo mouse bone marrow micronucleus (MN) assay. Results showed the biological
treatment reduced the frequency of MN, in a dose-dependent manner, when compared to
untreated sample. The decreasing of around 20% and 45% of phenolics concentration was
observed throughout the treatment, confirming that laccase production can be related to the
degradation of toxic compounds present in the effluent. Therefore, the biodegradation by the
P. sanguineus fungus seems a promising method for the mineralization of recalcitrant
compounds present in pharmaceutical effluents.
