摘要

The work investigated ecotoxic effects of commercial pesticides “Benito”, “Fascord”, “Ceriax® Plus”, “Potassium humate” and “Bio-Don 10” and their effect on bacterial biofilms and rifampicin-resistant mutant formation frequency of the Acinetobacter calcoaceticus strain VKPM B-10353. With the help of biotesting using whole-cell bioluminescent bacterial sensors, integral toxicity, genotoxicity, and capability of the studied pesticides to induce oxidative stress were determined. It was established that the “Fascord” drug has the highest ecotoxicity level among the studied pesticides. It causes oxidative stress and DNA damage, enhances mutagenesis, and also has a stimulating effect on bacterial biofilm formation. “Benito”, “Ppotassium humate”, “Bio-Don 10”, and “Ceriax® Plus” preparations also exhibit some toxicity and may pose an environmental hazard to the environment. The results highlight the need to assess environmental risks of both existing and new pesticides to the soil microbial community using a representative set of bioassays.
