AHON-RIOS, Karen Alejandra; RENGIFO-MENDEZ, Fiorella; IGLESIAS-OSORES, Sebastián e MERCADO-MARTINEZ, Pedro Estuardo. Antibacterial activity of zinc oxide nanoparticles against Listeria monocytogenes ATCC 7644. Rev. Cuerpo Med. HNAAA [online]. 2022, vol.15, n.1, pp.71-75. Epub 31-Mar-2022. ISSN 2225-5109. http://dx.doi.org/10.35434/rcmhnaaa.2022.151.1032.
Background:
Zinc oxide nanoparticles (Np-ZnO) have different behaviors which allows its application in various areas.
Objectives:
To determine the minimum inhibitory concentration (MIC) of Zinc oxide nanoparticles for Listeria monocytogenes ATCC 7644.
Material and Methods:
Zinc oxide nanoparticles with an average size of 90nm and different concentrations of 4; 2; 1; 0,5; 0,25; 0,12; 0,06; 0,03; 0,01; 0,007 mg/mL prepared in aqueous solution were used. It was incubated at a time corresponding to generation time of the bacteria, evaluating the growth with the presence of turbidity.
Results:
The MIC for Listeria monocytogenes ATCC 7644 was 0,06 mg/mL.
Conclusion:
The minimum inhibitory concentration (MIC) of Zinc oxide nanoparticles (Np-ZnO) with an average size of 90nm for Listeria monocytogenes ATCC 7644 was 0,06 mg/mL, enough value to significantly control the growth of for Listeria monocytogenes ATCC 7644.
