Resumo: | Currently, the success of nanotechnology affects several areas of science, medicine, technology and, especially, the food industry. Silver nanoparticles (Ag-NPs) stand out, with their antimicrobial effect. Salmonella is a cause of foodborne diseases and there are reports of resistant serotypes. The use of Ag-NPs is an alternative for bacterial control in foods. The aim of this study was synthesize, characterize and verify the antimicrobial activity of Ag-NPs on serotypes of Salmonella. The size of Ag-NPs was estimated and it was possible to detect two populations of 4.7 ± 0.09 and 35.7 ± 2.12. The zeta potential was -33.7 ± 11.8 mV indicating good dispersion stability.Ag-NP antimicrobial activity was determined from minimum inhibitory concentration (MIC).The lowest MIC found was 4.7 μg·mL-1 for Salmonella Enteritidis and the highest was 27.7 μg·mL-1 for Salmonella Infantis 1 isolate.The use of Ag-NPs is promising with respect to antimicrobial activity, however, improvements in synthesis methods should be explored in order to make commercial use viable. |

Se destacan las nanopartículas de plata (Ag-NP), con su efecto antimicrobiano. La salmonella es una causa de enfermedades transmitidas por los alimentos y hay informes de serotipos resistentes. El uso de Ag-NP es una alternativa para el control bacteriano en los alimentos. El objetivo de este estudio fue sintetizar, caracterizar y verificar la actividad antimicrobiana de Ag-NP en los serotipos de Salmonella. Se calculó el tamaño de Ag-NP y fue posible detectar dos poblaciones de 4.7 ± 0.09 y 35.7 ± 2.12. El potencial zeta fue de -33.7 ± 11.8 mV, lo que indica una buena estabilidad de la dispersión. La actividad antimicrobiana Ag-NP se determinó a partir de la concentración inhibitoria mínima (MIC). La MIC más baja encontrada fue de 4.7 μg • mL-1 para Salmonella Enteritidis y la más alta fue de 27.7 μg • mL-1 para el aislado de Salmonella Infantis 1. El uso de Ag-NPs es prometedor con respecto a la actividad antimicrobiana, sin embargo, se deben explorar mejoras en los métodos de síntesis para hacer viable el uso comercial.Atualmente o sucesso da nanotecnologia atinge várias áreas da ciência, medicina, da tecnologia e, principalmente, do setor alimentício. As nanopartículas de prata (Ag-NPs) ganham destaque com seu efeito antimicrobiano que além de altamente tóxicas à celulas bacterianas, são facilmente sintetizadas e caracterizadas. O gênero Salmonella é o segundo maior causador de doenças e já existem relatos de sorotipos altamente resistentes. Assim, o uso de Ag-NPs é uma alternativa para controle bacteriano em alimentos. O objetivo deste estudo foi sintetizar, caracterizar e verificar a atividade antimicrobiana de Ag-NPs sobre sorotipos de Salmonella. O tamanho das Ag-NPs foi estimado e foi possível detectar duas populações de 4,7 ± 0,09 e 35,7 ± 2,12. O potencial zeta foi de -33,7 ± 11,8 mV, indicando boa estabilidade da dispersão. A atividade antimicrobiana das Ag-NP foi determinada a partir da concentração inibitória mínima (CIM). A CIM mais baixa encontrada foi de 4,7 μg • mL-1 para Salmonella Enteritidis e a maior foi de 27,7 μg • mL-1 para o isolado de Salmonella Infantis 1. O uso de Ag-NPs é promissor em relação à atividade antimicrobiana, no entanto, melhorias nos métodos de síntese devem ser exploradas para viabilizar o uso comercial.Research, Society and Development2020-08-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/643510.33448/rsd-v9i9.6435Research, Society and Development; Vol. 9 No. 9; e103996435Research, Society and Development; Vol. 9 Núm. 9; e103996435Research, Society and Development; v. 9 n. 9; e1039964352525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/6435/6227Copyright (c) 2020 Luana Virgínia Souza, Daniela Abrantes Leal, Tayara Rodrigues da Costa, Regina Célia Santos Mendonçahttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSouza, Luana VirgíniaLeal, Daniela AbrantesCosta, Tayara Rodrigues daMendonça, Regina Célia Santos2020-09-18T01:42:11Zoai:ojs.pkp.sfu.ca:article/6435Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:29:34.444882Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
