genotoxicity; biodegradation; synthetic dyes; activated sludge; Irpex lacteus; Ames test

Detection of mutagenicity was carried out with three samples containing residues of textile dyes obtained from textile company Jitex Písek. Two different biodegradation processes were used for elimination of genotoxicity, biodegradation using the bacterial activated sludge and treatment by the ligninolytic fungus Irpex lacteus. The genotoxicity of samples was detected by the Salmonella typhimurium His- assay.
