摘要
欧亨尼奥-德阿尔梅达基金会的壁画之家（Casa de Fresco）是一座具有珍贵历史艺术价值的历史古迹，目前由于石材和罗钉构件中微生物的大量繁殖，该古迹出现了各种生物膜。作为保护和修复项目的一部分，我们对该区域的生物劣化情况进行了研究。我们利用现代高通量 DNA 分析方法有效地确定了当地微生物群落的特征。结果表明，这里存在多种地衣或地衣化真菌，包括 Variospora、Verrucaria、Circinaria 和 Caloplaca 等属。此外，我们还检测到几种与鉴定这些地衣有关的原核微生物。为了妥善处理这一微生物问题，避免真菌重新定殖，我们对现有的商业抗菌剂进行了评估。
The Decorated Garden Grotto of Condes de Basto Palace in Évora, Portugal: Microbial Community Characterization and Biocide Tests for Conservation
The Eugénio de Almeida Foundation’s Casa de Fresco is a historical monument of valuable historic–artistic significance, which currently reveals an assortment of biofilms due to the proliferation of microorganisms in the stone and rocaille elements. The biodeterioration in this area was studied as part of the Conservation and Restoration Project. We effectively characterized the local microbial community using modern high-throughput DNA analysis. Our results suggested the existence of a variety of lichens or lichenized fungi, including genera such as Variospora, Verrucaria, Circinaria, and Caloplaca. Furthermore, we detected several prokaryote microorganisms related to the identification of these lichens. To properly deal with this microbiological issue and avoid fungal recolonization, we evaluated available commercial antimicrobial treatments.
