Capacity of white-rot fungi Perreniporia tephropora for decolourization of different dyes in solid medium

The aim of this study is to evaluate the capacity to degrade synthetic dyes (Orange G, Reactive blue 4 and Methyl Orange) used in textile industry by white-rot fungus Perreniporia tephropora isolated from Gabonese forest. The isolate was able to decolorize different dyes in wide range (up to 0.3 g/L), at temperature 30°C in solid culture media. The results revealed that the discoloration dyes was important after 6 days and this fungus presented an optimum growth temperature between 30°C and 35°C. This fungus on solid culture media produces different enzymatic activities like laccase, phenoloxidase, and peroxidases, which represented their important role in biotransformation.
