dc.description.abstract | The environmental contamination of soil by metal oxide nanomaterials is a growing global concern because of their potential toxicity. We investigated the effects of Mg doped ZnO (Mg-nZnO) nanoparticles on a model soil microorganism Bacillus subtilis. Mg-nZnO exhibited only a moderate toxic effect on B. subtilis vegetative cells but was able to prevent biofilm formation and destroy already formed biofilms. Similarly, Mg-nZnO ( lt = 1 mg/mL) was moderately toxic towards Listeria monocytogenes, Staphylococcus aureus, Escherichia coli, Salmonella enterica, Saccharomyces cerevisiae and murine macrophages. Engineered Mg-nZnO produced H2O2 and O-2(center dot-) radicals in solutions of various salt and organic molecule compositions. A quantitative proteomic analysis of B. subtilis membrane proteins showed that Mg-nZnO increased the expression of proteins involved in detoxification of ROS, translation and biofilm formation. Overall, our results suggest that Mg-nZnO released into the environment may hinder the spreading, colonization and biofilm formation by B. subtilis but also induce a mechanism of bacterial adaptation. | en |
