Resumo: | Pseudomonas aeruginosa is an opportunistic pathogen capable of forming biofilms of great relevance to medical microbiology and the food industry. Essential oil (EOs) constituents have been researched as new strategies for the control of biofilms. In the present study cinnamaldehyde was shown to be an effective EO against the planktonic cells of P. aeruginosa strains (p < 0.05). Thus it was used to prepare sanitizing solutions, which were tested against P. aeruginosa biofilms formed on stainless steel surfaces. Cinnamaldehyde showed antibacterial activity against sessile P. aeruginosa cells (p < 0.05). A 100% (5.87 log-reduction) elimination of viable bacterial cells was obtained after treatment with a 6xMIC (0.06% Minimal Inhibitory Concentration) solution for the strain ATCC 9027. Sanitizing cinnamaldehyde solutions can be used as new alternatives to control such microbial sessile communities in food industries. |

Os constituintes do óleo essencial (OE) têm sido pesquisados como novas alternativas para o controle do biofilme. Neste estudo, o cinamaldeído mostrou-se eficaz como OE contra células planctônicas de cepas de P. aeruginosa (p < 0,05) e foi então utilizado para a preparação de soluções sanitizantes que, por sua vez, foram testadas contra biofilmes de P. aeruginosa formados em superfície de aço inoxidável. Cinamaldeído mostrou atividade antibacteriana contra células sésseis de P. aeruginosa (p < 0,05). Para a estirpe ATCC 9027, foi obtida uma eliminação de células bacterianas viáveis em 100% (5,87 log-redução), após tratamento com a solução 6xMIC (0,06% Concentração Inibitória Mínima). As soluções sanitizantes de cinamaldeído podem ser novas alternativas para o controle dessas comunidades sésseis microbianas na indústria alimentícia.Instituto de Tecnologia de Alimentos - ITAL2020-06-15T19:06:53Z2020-06-15T19:06:53Z2019-05info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfPEREIRA, L.
