antibacterial activity of a malodor neutralizer containing silver nanoparticles

in this study bactericidal activity of a malodor neutralizer containing silver nanoparticles manufactured in iran has been tested. for this purpose different concentrations of the product encounter with staphylococcus aureus, pseudomonas aeruginosa and bacillus cereus then the activity were evaluated in different contact times. the products containing at least 200 ppm of silver nanoparticles were effective on all of bacterial strains and higher exposure time increased its antibacterial activity. bactericidal activity against spore of bacillus cereus was less obvious in comparison with other bacteria. it seems that silver nanoparticle is a valuable antibacterial agent even in presence of aromatic fragments and could be applied as disinfectant in many situations.
