Reduction in the Mutagenicity of Synthetic Dyes by Successive Treatment with Activated Sludge and the Ligninolytic Fungus, Irpex lacteus
Original language description
Synthetic dyes are released in wastewater from textile manufacturing plants, and many of these dyes are genotoxic. In the present study, the mutagenicity of azo, anthraquinone, and triphenyl methane dyes was investigated before and after successive biodegradation with activated sludge and the ligninolytic fungus, Irpex lacteus. Two biodegradation systems were used in order to reduce the genotoxicity of dyes that were not efficiently inactivated by activated sludge alone. Mutagenicity was monitored withthe Salmonella reversion assay conducted with the base-pair substitution detector strains, TA100 and YG1042, and the frame-shift detector strains, TA98 and YG1041, with and without rat liver S9. All dyes except for Congo Red were mutagenic with S9 activation. Assays conducted with the dyes indicated that only the azo dye Reactive Orange 16 (RO16) was mutagenic in both TA98 and TA100

Snížení mutagenity syntetických barviv následným působením aktivovaného kalu a ligninolytické houby Irpex lacteus
Czech description
Syntetická barviva jsou přítomna v efluentech z textilního průmyslu a mnoho z nich vykazuje genotoxické účinky. V této práci byla studována mutagenita azo, antrachinonových a trifenylmetanových barviv před a po následné biodegradaci aktivovaným kalem a ligninolytickou houbou I. lacteus. Mutagenita byla sledována pomocí testu se Salmonella typhimurium. Všechna berviva vyjma Congo Red byla mutagení po S9 aktivaci. Methyl Red a Disperse Blue 3 byly mutagení v testu s kmeny TA98, YG1041 a YG1042 zatímco Reactive Black 5 byla mutagenní s kmeny YG1041 a YG1042. Congo Red nevykazovala žádné mutagenní účinky ani s jedním z testovaných bakteriálních kmenů
