Abstract During the ongoing characterization of limestone biodeterioration in the UNESCO World Heritage site of “University of Coimbra – Alta and Sofia” (Coimbra, Portugal), it was brought to our attention that the limestone relieves adorning the tomb of D. Afonso I (First Portuguese King), displayed several signs of distinctive biodeterioration patterns. According to the ICOMOS Illustrated glossary on stone deterioration patterns, these could be characterized as visual mould proliferation, presence of black crusts, stone erosion and disintegration. Due to the invaluable nature of this monument, a multi-disciplinary approach (biological and analytical) to fully characterize these phenomena was applied. The results obtained allowed the characterization of the fungal diversity colonizing this monument, as well as the identification of various deterioration products. The results highlighted that the detected indoor black crusts displayed various characteristics from polluted environments, although lacking the typical association with gypsum. The black crusts were also characterized by the presence of lead oxides, damaging salts and carbonaceous particles. In addition, it could be verified that the erosion phenomena found are a result from fungal mediated calcium carbonate dissolution and calcium oxalate formation. The establishment of different fungal populations coupled with the deposition of environmental particles contributed to the development of the distinct phenomena detected through differential biodeterioration mechanisms.

多分析法分析第一个葡王墓真菌变质现象

摘要 在联合国教科文组织世界遗产“科英布拉大学 - 阿尔塔和索非亚大学”(葡萄牙科英布拉)正在进行的石灰石生物退化表征过程中,我们注意到石灰石减轻了 D. Afonso I 墓的装饰(第一葡萄牙国王),显示出几个独特的生物退化模式的迹象。根据 ICOMOS Illustrated 关于石材退化模式的词汇表,这些可以表征为可见的霉菌增殖、黑色结皮的存在、石材侵蚀和崩解。由于这座纪念碑的宝贵性质,应用了多学科方法(生物学和分析)来充分表征这些现象。获得的结果允许表征在这座纪念碑上定居的真菌多样性,以及各种变质产物的鉴别。结果强调,检测到的室内黑色结壳显示出来自污染环境的各种特征,尽管缺乏与石膏的典型关联。黑色结皮的特征还在于存在氧化铅、破坏性盐和碳质颗粒。此外,可以证实发现的侵蚀现象是真菌介导的碳酸钙溶解和草酸钙形成的结果。不同真菌种群的建立以及环境颗粒的沉积促成了通过差异生物恶化机制检测到的不同现象的发展。结果强调,检测到的室内黑色结壳显示出来自污染环境的各种特征,尽管缺乏与石膏的典型关联。黑色结皮的特征还在于存在氧化铅、破坏性盐和碳质颗粒。此外,可以证实发现的侵蚀现象是真菌介导的碳酸钙溶解和草酸钙形成的结果。不同真菌种群的建立以及环境颗粒的沉积促成了通过差异生物恶化机制检测到的不同现象的发展。结果强调,检测到的室内黑色结壳显示出来自污染环境的各种特征,尽管缺乏与石膏的典型关联。黑色结皮的特征还在于存在氧化铅、破坏性盐和碳质颗粒。此外,可以证实发现的侵蚀现象是真菌介导的碳酸钙溶解和草酸钙形成的结果。不同真菌种群的建立以及环境颗粒的沉积促成了通过差异生物恶化机制检测到的不同现象的发展。破坏盐和碳质颗粒。此外,可以证实发现的侵蚀现象是真菌介导的碳酸钙溶解和草酸钙形成的结果。不同真菌种群的建立以及环境颗粒的沉积促成了通过差异生物恶化机制检测到的不同现象的发展。破坏盐和碳质颗粒。此外,可以证实发现的侵蚀现象是真菌介导的碳酸钙溶解和草酸钙形成的结果。不同真菌种群的建立以及环境颗粒的沉积促成了通过差异生物恶化机制检测到的不同现象的发展。
