Evaluation of genotoxicity in industrial waste waters

Abstract

This article presents the results of a research dealing with the detection of mutagenic activity of two samples used in the textile industry, Methylene Blue synthetic dye and Inotex real dye bath before, during and at the end of the biodegradation process by means of ligninolytic fungus Irpex lacteus. There is evidence that Methylene Blue synthetic dye was detected as an indirect mutagen prior to the biodegradation process. However, the biodegradation intermediate product was evaluated as a direct mutagen and the final product of biodegradation no longer induced any mutagenic activity. Inotex dye bath samples were assessed as non-mutagenic.
