Research Article: Antimicrobial effects of silver/copper/titanium dioxide-nanocomposites synthesised by chemical reduction method to increase the shelf life of caviar (Huso huso)
چکیده:   (251 مشاهده)
This paper focuses on the use of incorporation of silver (Ag) and copper (Cu) nanoparticles in titanium dioxide (TiO2) nanocomposites, as Ag/Cu/TiO2 nanocomposite was synthetized through the chemical reduction method against food borne microorganisms. The antimicrobial effect of Ag/Cu/Tio2 nanocomposite demonstrated a considerable antimicrobial activity as order as Escherichia coli > Staphylococcus aureus > Aspergillus niger. The results of the agar diffusion test exhibited no halo growth around the discs of four nanocomposite samples, which indicated the perfect inhibitory effect of synthesized Ag/Cu/TiO2 nanocomposites against the afore-mentioned bacteria. Scanning electron microscopy (SEM) analysis exhibited that Ag and Cu nanoparticles were homogeneously distributed into the TiO2 nanocomposite. Furthermore, the results of inductive coupled plasma mass spectrometry (ICP-MS) method showed that 0/168 ppm of Ag was released to caviar samples on 32nd day and 62nd days of the experiment. All findings indicated that the combined usage of Ag/Cu/Tio2 nanoparticles could meet all desirable objectives including increase of antimicrobial activity and reduction release of Ag nanoparticles into the caviar, which extends caviar shelf life.
