Article Synopsis
  • Four novel strains resistant to copper were tested against newly synthesized copper oxide nanoparticles (CuO and CuO NPs).
  • Characterization methods confirmed the successful creation of these nanoparticles, which showed superiority in inhibiting bacterial growth due to their ability to induce oxidative stress.
  • The study highlighted that CuO NPs not only reduced biofilm formation in copper-resistant strains but also revealed different responses based on the bacterial species, demonstrating the potential of nanotechnology in addressing metal tolerance in bacteria.

This study presents high-quality draft genome assemblies of six bacterial strains isolated from the roots of wheat grown in soil contaminated with cadmium. The results of this study will help to elucidate at the molecular level how heavy metals affect interactions between beneficial rhizobacteria and crop plants.

Environmental copper pollution causes major destruction to ecological systems, which require the development of environmentally friendly biotechnological, in particular, microbial methods for copper removal. These methods rely on the availability of microorganisms resistant to high levels of copper. Here we isolated four bacterial strains with record resistance to up to 1.

Antarctic plants are stable specific microenvironments for microbial colonization that are still less explored. In this study, we investigated cultivable heterotrophic bacteria and yeasts dominating in plant samples collected from different terrestrial biotopes near Ukrainian Antarctic Base on Galindez Island, maritime Antarctica. Phylogenetic analysis revealed affiliation of the bacterial isolates to genera Pseudomonas, Stenotrophomonas, Brevundimonas, Sporosarcina, Dermacoccus, Microbacterium, Rothia and Frondihabitans, and the yeast isolates to genera Rhodosporidium, Cryptococcus, Leucosporidiella, Candida and Exophiala.
