Resumo

A aplicação de biocidas para controlar a proliferação microbiana em materiais rochosos é hoje em dia uma prática bastante comum. 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.
