On the other hand, nanocomposites containing cobalt nanoparticles had the highest anti-bacterial potential when cobalt was displayed on the surface. aeruginosa, which indicates the possibility of increased virulence. We have found that particularly nanomaterials containing TiO 2 could induce pigmentation in P. Furthermore, a specific concentration of a given nanomaterial could cause contradictory effects leading to stimulation or inhibition of pigmentation, an optical density of the cultures, or biofilm formation. The co-incubation with the nanostructures (in concentration 125 µg/mL) could inhibit the population growth (in most cases) or promote it in the case of graphene oxide. aeruginosa to tested nanostructures, depending on their concentration. The results confirmed variability in the response of P. The optical density of cultures, pigment production, respiration, growth curve analysis, and biofilming were tested. Concentrations ranging from 15.625 to 1000 µg/mL were tested. Therefore, we aimed to test selected carbon nanomaterials and their components in a series of experiments describing the basic physiology of P. Testing other microorganisms, such as Pseudomonas aeruginosa, could provide novel insights into the microbial response to nanomaterials. Such experimental design does not show the dynamic changes in bacterial physiology, mainly when performed on reference microorganisms ( Escherichia coli and Staphylococcus aureus). Experiments describing properties of nanomaterials on bacteria are frequently limited to the disk diffusion method or other end-point methods indicating viability or survival rate in plate count assay.
