Activated sludge; Ames test; Biodegradation; Irpex lacteus; Ligninolytic fungus; Synthetic dyes

The purpose was to study the genotoxic effect of selected synthetic dyes and found out whether during biodegradation with activated sludge bacteria and ligninolytic fungus Irpex lacteus mutagenic products are formed. Ames test was used to monitor the production of mutagenic compounds during biodegradation and was also applicable to detect whether, in the case of compounds exhibiting a certain mutagenic effect, the biodegradation process was able to significantly reduce their mutagenic potential. Another purpose was to assess whether the results of mutagenicity tests could be used for the evaluation of efficiency of the biodegradation processes and/or whether the individual biodegradation processes could be compared using the results obtained and optimized on this basis.
