Effect of laccase from Hypsizygus ulmarius in decolorization of different dyes.

The objective of the study was to check the laccase (purified from Hypsizygus ulmarius) for decolorization of different dyes. The purified laccase from Hypsizygus ulmarius was studied for its decolorization of different dyes (Remazol brilliant blue R (RBBR), Alizarin red, Congo red, methyl orange and methyl violet). The results indicated that the percent of decolorization was increased when the time course and enzyme concentration was increased. The purified laccase showed maximum amount of decolorization in RBBR (85%) and followed by Methyl Orange (75%), Alizarin Red (73%), Methyl Violet (72%) and Congo Red (69%) without any additional redox mediator which suggest that this enzyme could be used in industries for effluent treatment.
