The decolorization of dye and textile effluent by Trametes hirsuta was studied in both induced and non-induced media. A removal of 70-100% of the color was achieved through adsorption and the action of laccases. Laccase activity was increased significantly with the addition of grapefruit peel (4000 U/mL) and effluent with grapefruit peel (16,000 U/mL) in comparison with the basal medium (50 U/mL). Analysis of the expression of laccase isoenzymes lac-B and lac-T revealed clear differences in the expression of these genes. The low levels of expression of lac-B in all media suggest a basal or constitutive gene expression, whereas lac-T was over-expressed in the media with effluent, and showed an up/down regulation depending on culture conditions and time. The results obtained suggest that the lac-T gene of T. hirsuta is involved in the decolorization of dyes.
