“…This phenomenon was observed only in areas close to the place where the inoculum was deposited. Despite showing the same alteration but more spread, EDS analysis of the sample C2 indicated an atypical increase of calcium, which is probably related to the residues of the organic material from the hyphae (Drewello et al, 2000). A slight depletion of Al2O3 was also observed, which could be related to the leaching of aluminum from the glass surface.…”

“…Nevertheless, soda-lime silicate glass is commonly known by its stability in comparison with other historical glass compositions, such as potash-lime silicate, because their hydration process is long and slow (García-Heras et al, 2005;Piñar et al, 2013;Palomar et al, 2017). The chemical stability of the glass in a humid environment favoured the poor interaction between the inoculated fungi and the glass matrix since the higher supply of adsorbed water is required to make the glass more attractive for microbes (Drewello et al, 2000).…”

“…The microbial colonization on glass windows is related to the climate and to a high concentration of air pollutants, among other factors. The main effects of biogenic attack on historical glass, include etching, pitting, leaching, discoloration, glass degradation, formation of gel layers, and intense soiling on the original glass surface, as reported in the literature (Drewello et al, 2000;Lombardo et al, 2005;Piñar et al, 2013;Rodrigues et al, 2014;Shirakawa et al, 2016). Most of these effects induce the loss of transparency, which directly affects not only the stained glass aesthetics, but also its iconographic function (Carmona et al, 2006).…”

“…The role of microorganisms in glass deterioration has been largely discussed during the last decades, mainly in European stained-glass windows (Drewello and Weissmann, 1997;Gorbushina and Palinska, 1999;Drewello et al, 2000;Rodrigues et al, 2014). The microbial colonization on glass windows is related to the climate and to a high concentration of air pollutants, among other factors.…”

The most prominent historical buildings in Belém do Pará (Northern Brazil) have modernist stained-glass windows, which were commissioned from Europe since the end of the 19 th century. Some of them present biodegradation; however, there is no information about the microbial activity on them. The present work is focused on the biodeterioration by fungi on some of these Modern stained-glass windows. The fungal communities were collected, isolated and then identified by means of molecular methods. Additionally, a laboratory-based biodeterioration experiment was carried out to assess the fungal activity on replica glass samples with three different chemical compositions. The replica samples were inoculated with a four-fungal species mixture and incubated under optimal growth conditions for 5 months. Optical microscopy, µ-PIXE, SEM-EDS and FTIR-ATR were performed to evaluate the biodeterioration of the soda-lime silicate glasses. This multidisciplinary approach showed that the inoculated spores (Aspergillus arenarioides, Fusarium oxysporum, Hortaea werneckii, and Trichoderma longibrachiatum) were able to form substantial mycelia in all replica glass samples. The main alterations observed were small crystals, hyphae fingerprints and a slight decrease on the glass surface smoothness. Despite the aforementioned damages, the soda-lime silicate glass compositions showed high resistance against the inoculated fungal species.

“…In the Mediterranean basin, most of the monuments (stone and glass), deserted quarries and natural outcrops show a common and uniform ochre-orange patina, in some cases alternated with a black patina of different composition (Blázquez et al 1997;Garcia-Valles et al 1996a, b, 1997. They are characterized by neoformed mineral phases (sometimes associated with bioactivity; Urzì and Realini 1998;Drewello and Weissmann 1997;Drewello et al 2000), which are stable in special environmental conditions. Santa Maria de Pedralbes Monastery (Fig.…”
