“…Here, we show that the most common fungal spores found in these confined air spaces, such as in churches, chapels, crypts, and other similar closed areas, are represented by the genera Cladosporium, Penicillium, Aspergillus, Alternaria and Fusarium. The comparison with other studies in Literature evidenced as the main genera recorded (Cladosporium, Penicillium, Aspergillus) in the present work were in line with those previously carried out (Montacutelli et al, 2000;Aira et al, 2007;Pangallo et al, 2012;Rojas et al, 2012). These types of spores can then also lead to serious consequences for plasterwork and paintings (Nugari et al, 1993).…”

Biodegradative potential of fungal isolates from sacral ambient: In vitro study as risk assessment implication for the conservation of wall paintings

et al. 2018

The principal purpose of the study was to evaluate in vitro the potential ability of fungal isolates obtained from the painted layer of frescoes and surrounding air to induce symptoms of fresco deterioration, associated with their growth and metabolism, so that the risk of such deterioration can be precisely assessed and appropriate conservation treatments formulated. Biodegradative properties of the tested microfungi were qualitatively characterized through the use of a set of special agar plates: CaCO3 glucose agar (calcite dissolution), casein nutrient agar (casein hydrolysis), Czapek-Dox minimal medium (pigment secretion); and Czapek-Dox minimal broth (acid and alkali production). Most of the tested isolates (71.05%) demonstrated at least one of the degradative properties, with Penicillium bilaiae as the most potent, since it tested positive in all four. The remaining isolates (28.95%) showed no deterioration capabilities and were hence considered unlikely to partake in the complex process of fungal deterioration of murals via the tested mechanisms. The obtained results clearly indicate that utilization of fast and simple plate assays can provide insight into the biodegradative potential of deteriogenic fungi and allow for their separation from allochthonous transients, a prerequisite for precise assessment of the amount of risk posed by a thriving mycobiota to mural paintings.

“…Ecological classification included the following groups: P (phytopathogens), H (human pathogens), and S (saprobic fungi), as well as their combinations (HP, HS, PS, and HPS). As for biodegradation properties, the fungal taxa were classified into six groups (G0-G5) (6,7,(27)(28)(29), with the G5 group having all five properties (carbonate dissolution, acid and alkali production, c a s e i n h y d r o l y s i s , p i g m e n t s e c r e t i o n a n d organomineralization), G4 having four properties, and so on. Data for both classifications were arranged in the same manner.…”

“…In recent years, monitoring of fungal propagules in the indoor environment of cultural heritage objects such as churches, museums, libraries, and archives has become an important part of preventive conservation (5)(6)(7)(8). Regardless of the growing interest, monitoring studies of this type have been scarce in Serbia, and none had been conducted in sacral complexes.…”

The main purpose of this study was to isolate airborne fungi and assess seasonal variations in air contamination with their particulates by determining the levels of their propagules in the nave and exonarthex of a church. We also monitored indoor microclimate as a determining factor for fungal proliferation on wall paintings, spore release, and transmission through the air. The temperature and relative humidity of the nave favoured fungal growth. A total of 33 fungi were isolated, mainly of the phylum Ascomycota, and to the lesser extent of the phyla Zygomycota and Basidiomycota. The most common were the fungi of the genera Penicillium and Aspergillus (23.55 % and 20.58 %, respectively). Sørensen’s quotient of similarity (0.37) suggests moderate species overlap and constant exchange of fungal propagules between the nave and exonarthex. The autumn had the highest diversity, with 17 documented taxa, followed by the summer and the winter. The spring had only eight taxa. Quantitative analysis of the airborne mycobiota in the nave (430±84.85 to 1880±106.07 CFU m-3) and exonarthex (715±59.62 to 2295±91.92 CFU m-3) showed very high contamination throughout the year, with values exceeding the maximum permissible concentrations by most standards. Many of the fungi determined in this study are known for their biodeteriogenic, toxigenic, and allergenic properties, and are a threat not only to occasional visitors and staff, but also to valuable works of art decorating nave walls.
