Resumo: The application of biocides to control microbial proliferation in stone materials is nowadays a rather common practice. In the Coimbra´s UNESCO World heritage monuments, biocide treatments rely on the application of Biotin T and Preventol R80. However, the application of these formulations often occurs without the complete knowledge of microbial communities’ susceptibility to their application. The aim of this study was to evaluate the efficiency of these compounds and compare them with a commercial version of Ocimum basilicum essential oil, against various fungal species present in these areas. Through the application of in vitro antifungal activity assays, we were able to verify that, in general, Biotin T rather than Preventol R80 was more efficient against all tested fungi. In addition, the commercial version of the Ocimum basilicum essential oil also exhibited good results and might be an alternative option to be taken into consideration in future interventions in these monuments.

Nos monumentos do património mundial da UNESCO de Coimbra, os tratamentos à base de biocidas têm consistido na aplicação de Biotin T e Preventol R80. No entanto, a aplicação dessas formulações ocorre muitas vezes sem o conhecimento completo da suscetibilidade das comunidades microbianas à sua aplicação. O objetivo deste estudo foi avaliar a eficiência destes compostos e compará-los com uma versão comercial do óleo essencial de Ocimum basilicum, contra várias espécies de fungos presentes nessas áreas. Por meio da aplicação de ensaios de atividade antifúngica in vitro, pudemos verificar que, em geral, o Biotin T, comparativamente ao Preventol R80, foi mais eficiente contra todos os fungos testados. Adicionalmente, a versão comercial do óleo essencial de Ocimum basilicum também apresentou bons resultados e pode ser uma opção alternativa a ser considerada em futuras intervenções nestes monumentos.ARP - Associação Profissional de Conservadores-Restauradores de Portugal2023-07-09info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://doi.org/10.14568/cp25076eng2182-99421646-043XTrovão, JoãoPortugal, Antónioinfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-07-11T02:30:33Zoai:ojs.revistas.rcaap.pt:article/25076Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T17:49:05.993672Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
