ABSTRACT

Six strains of Pseudomonas aeruginosa were used for experiments of the action of Ag nanoparticles embedded in starch matrix on growth. The strains were inoculated on medium TSA + 5% blood agar, and incubated for 24h in 37 ºC. Experiments were performed using different concentrations (55, 100, 150 and 220 ppm) of Ag nanostructures in growing medium (TSA + 5% blood agar). Bacterial strains were grown on the solid medium for 5 days at temperature 37 ºC. Concentration depended effect of microorganisms growth inhibition was observed. Total growth of both bacterial strains was completely stopped at nano Ag concentration of 220 ppm.
