Description
Summary:CeO 2 nanomaterials have attracted a wide attention due to their applications, specially, as antibacterial and antifungal agents in the biomedical applications. In the current work, Fe-doped CeO 2 nanoparticles (with different iron doping concentrations) stabilized with xanthan gum as a green capping agent were prepared by co-precipitation synthesis and characterized by using X-ray diffraction, transmission electron microscope. Inhibitory activity of Fe-doped CeO 2 nanoparticles was evaluated against pathogens including Pseudomonas aeruginosa , Listeria monocytogenes , Candida albicans and Fusarium oxysporum via broth micro-dilution and streak plate methods. Good to excellent antimicrobial effects were observed with nanoparticles. These compounds can be used as food preservatives according their low toxicity and acceptable antimicrobial properties.
