Studie je zaměřena na detekci mutagenity vybraných syntetických barviv s využitím kmenů Salmonella typhimurium His- YG. Dílčím cílem studie bylo na základě stanovení mutagenní aktivity metabolických produktů barviv posoudit, zda jsou aplikované biodegradační metody dostatečně účinné k degradaci syntetických barviv.

Synthetic dyes find utilization in a wide range of industries, particularly in textile manufacturing. Many of these dyes are lost to the wastewater during textile processing and they contaminate the environment. The purpose of the study was to detect mutagenicity of different synthetic dyes. For the assessment of genotoxicity of the samples we used the Ames test with the utilization of bacterial strains of Salmonella typhimurium His- YG1041 and YG1042 for the detection of mutagenicity of nitroderivates. This survey presents the changes in mutagenicity of the metabolic products of the dyes during two biodegradation technologies.
