Resumo
The dyes are compounds widely used by various industries. The azo-dyes
are the most used. The main dyestuffes used by pharmaceutical industry are
tartrazine yellow and sunset yellow. These compounds can offer toxic,
mutagenic and carcinogenic risks. That study proposes the use of a biological
method of treatment using white-rot fungi that produce ligninolytic
enzymes to be able to degrade an enormous number of polluents. Assays
were made with the two dyestuffs cited using five fungal species. So, the
relationship between the decolourization and enzyme activity was made by
an average of 25 days. The best results of the both assays were obtained by
Tramestes versicolor, great producer of the enzyme laccase, while the other
fungi reported only a subtle decolourization. Thus, the laccase had a
relationship more evident with the removal process color.
