Abstract

Biodegradation of Orange II, Tropaeolin O, Congo Red, and Azure B in cultures of the white rot fungus, Phanerochaete chrysosporium, was demonstrated by decolorization of the culture medium, the extent of which was determined by monitoring the decrease in absorbance at or near the wavelength maximum for each dye. Metabolite formation was also monitored. Decolorization of these dyes was most extensive in ligninolytic cultures, but substantial decolorization also occurred in nonligninolytic cultures. Incubation with crude lignin peroxidase resulted in decolorization of Azure B, Orange II, and Tropaeolin O but not Congo Red, indicating that lignin peroxidase is not required in the initial step of Congo Red degradation.
