Abstract

The Museu Imperial has an important historical collection from the Portuguese Royal Family in Brazil. The throne represents the imperial power and is considered one of the most important objects in the museum; however, the piece has been facing for decades a gradual deterioration, mainly in its fabrics. With the growing motivation to preserve this property, conservation and restoration processes were conducted in all parts of the throne. As a part of this treatment, a microbiological survey was conducted in selected parts of the object and the surrounding environment where it was placed. This biodeterioration study, control and detection of microbial species indicated a very pertinent answer in relation to the place it was exposed, and the restoration process was performed in order to solve the most pronounced damages aiming to restore the original characteristics of the artefact. The study indicated a high diversity of fungi and bacteria. It was observed a marked decrease, before and after restoration, being observed the recurrence of the genera Absidia, Cladosporium and Epicoccum. This reduction was not so pronounced for bacteria, being also observed the recurrence of some bacterial groups after restoration (Microbacterium, Staphylococcus and Kocuria). In the atmosphere new fungal species were found after restoration, indicating a natural recontamination of the exhibition area.
D.佩德罗二世皇位周围和选定部分的微生物多样性——修复干预前后通过经典微生物学和分子生物学进行表征
帝国博物馆收藏了来自巴西葡萄牙王室的重要历史藏品。王座代表着皇权,被认为是博物馆中最重要的物品之一;然而,几十年来,这件作品一直面临着逐渐退化的问题,主要是在面料方面。随着保护这一财产的动机越来越强烈,王位的各个部分都进行了保护和修复工作。作为该处理的一部分,对物体的选定部分和放置物体的周围环境进行了微生物调查。这项对微生物物种的生物退化研究、控制和检测表明,对于其暴露的地方,有一个非常中肯的答案,进行修复过程是为了解决最明显的损伤,旨在恢复文物的原始特征。这项研究表明真菌和细菌的多样性很高。在恢复前后,观察到Absidia属、Cladosporium属和Epicoccum属的复发率显著下降。细菌的这种减少并不那么明显,也观察到一些细菌群在修复后复发(微生物、葡萄球菌和柯库氏菌)。修复后,在大气中发现了新的真菌物种,这表明展区受到了自然污染。

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.
