Abstract

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.

评价目前在科英布拉联合国教科文组织地区石灰石古迹中应用的杀菌剂的抗真菌效果

目前，使用杀菌剂控制石材中微生物的繁殖是一种相当普遍的做法。在科英布拉的联合国教科文组织世界遗产中，生物杀灭剂的处理依赖于生物素T和预防R80的应用。然而，这些制剂的应用往往在没有完全了解微生物群落对其应用的敏感性的情况下发生。本研究的目的是评估这些化合物的效率，并将它们与商业版本的罗勒精油进行比较，以对抗这些地区存在的各种真菌物种。通过体外抗真菌活性测定的应用，我们能够验证，在一般情况下，Biotin T比preventtol R80对所有测试真菌更有效。此外，商业版basilicum精油也显示出良好的效果，可能是未来对这些古迹进行干预时考虑的替代选择。

期刊介绍： Conservar Património is a journal, published three times a year, that intends to create a space for the diffusion of conservator-restorers’ studies and activities. However, at a time when Conservation-Restoration pretends to develop further through collaboration with other areas of knowledge, such as History of Art, Archaeology, Museum Studies, Chemistry, Physics, Biology and other related disciplines from the fields of the natural and social sciences, the journal also receives contributions from any other provenance as long as directed towards the multiple dimensions of the works that integrate our Cultural Heritage. Theoretical issues on the conservation activity may also be submitted.
