Abstract

In the heritage field, the microbial adhesion on wood, and consequently the formation of biofilm led to inestimable losses of historical and cultural monuments. Thereby, this study aimed to examine the combined effect of Thymus vulgaris, Myrtus communis, and Mentha pulegium essential oils on wood surface physico-chemical properties, and to elaborate the optimal mixture using the mixture design approach coupled to the contact angle method. It was found that both wood hydrophobicity and electron donor character increased significantly after treatment using an optimal mixture containing 57% and 43% of M. pulegium and M. communis essential oils, respectively. The theoretical and experimental fungal adhesion on untreated and treated wood were also investigated. The results showed that the adhesion was favorable on untreated wood and reduced using the optimal mixture. Moreover, the experimental data demonstrated that the same mixture exhibited an antiadhesive efficacy effect with a reduction of 36–75% in adhesion.

摘要

在遗产领域，微生物粘附在木材上，从而形成生物膜，导致历史文化古迹遭受不可估量的损失。因此，本研究旨在研究百里香、香桃木和薄荷精油对木材表面理化性质的综合影响，并利用与接触角法相结合的混合物设计方法来制定最佳混合物。结果发现，使用分别含有 57% 和 43% 的M. pulegium和43% 精油的最佳混合物处理后，木材的疏水性和电子供体特性均显着增加。还研究了未处理和处理过的木材上的真菌粘附的理论和实验。结果表明，未经处理的木材的附着力良好，但使用最佳混合物后，附着力会降低。此外，实验数据表明，相同的混合物具有抗粘附功效，粘附力降低了 36-75%。
