“…In contrast, a relatively low concentration of airborne fungi was measured indoors. These results agree with previous measurements in the Historical Museum of Crete as well as in other cultural heritage collections (Lazaridis et al, 2015;Lazaridis et al, 2018).…”

“…Absence or very low enrichment of airborne fast-growing fungi (I/O ratio: 0.1 -3) could be detected inside the Historical Museum of Crete during the measurement period. These results are in accordance to measurements in other cultural heritage collections where the microclimatic conditions are well controlled by HVAC systems, probably, due to absence of fungal emission sources indoors and the low outdoor air supply (Gauzere et al, 2014;Lazaridis et al, 2015;Lazaridis et al, 2018). Petushkova and Kandyba (1999) found also that the majority of the airborne microbes inside the Moscow Kremlin…”

“…Different selective microbiological growth media were used for the cultivation of viable airborne microbes (Lazaridis et al, 2015;Lazaridis et al, 2018;Katsivela et al, 2017). Two sequential repetitions on each specific growth medium were done at each site.…”

“…Microorganisms have been shown to present an important risk for cultural heritage objects, especially organic objects such as wood, woollen fabric, leather, and paper (Brimblecombe et al, 1999;Gauzere et al, 2013;2014, López-Miras et al, 2013Lazaridis et al, 2018). In addition, an important factor for the preservation of organic materials indoors in collections is the proper maintenance and climatic conditions of the museum microenvironment.…”

“…Orlandi et al, (2015) found a high variability of fungal bioaerosols in the crypt of St. Peter in Perugia with higher concentrations during summer. Biodegradation of art objects has been studied in the scientific literature and specific fungal and bacterial strains have been identified to deteriorate organic materials (Gallo, 1993;Lazaridis et al, 2015;Lazaridis et al, 2018;Pasquarella et al, 2015;Di Carlo et al, 2016). The deterioration depends on the structure of the material itself and the chemical composition of the substrate.…”

Measurements of viable ambient microbial levels and of microbial deposits on surfaces were performed in the Historical Museum of Crete for a period of two years. The concentrations of airborne microbes in museum rooms showed a considerable variability, which is mainly related to indoor activities (such as the number of visitors), the regulation of the indoor environmental conditions and air exchange rate, the chemical composition and conservation treatment of the exhibits, as well as the cleaning and storage conditions. An enrichment of acid producing bacteria, heterotrophic bacteria, and autotrophic chemolithotrophic bacteria was encountered indoors. A considerable decrease of the measured viable microbes was measured after the deployment of photocatalytic ionizers in the different indoor sites ranging from 5.5 % to 76 %. The use of photocatalytic ionizers improved the air quality by reducing mainly the presence of acid producing bacteria, which may cause the deterioration of cultural heritage objects. The microbial colonization on 24 different painting materials and surfaces of model essays, without the use of any preservation treatment, was examined for an exposure period of 18 months. The results from the bacterial deposition on paintings showed a gradual colonization, specific to the materials and surfaces, in concentrations ranging from 10 to 300,000 CFU cm-2. Although airborne fungi were measured in the exhibition rooms (yearly average concentration: 143 ± 115 CFU m-3), no growth of fungi could be detected on the majority of the used painting materials of the model essays. Very slow fungal surface colonization could be only determined on tempera, charcoal, wax pastel, and carton board in low concentrations ranging from 70 to 200 CFU cm-2 .

Microorganisms in the Deterioration and Preservation of Cultural Heritage

Microorganisms form the backbone of life on Earth. Over billions of years, they have colonized and shaped every possible niche on the planet. Microbes have modelled both the land and the sea, and have created favourable conditions for multicellular organisms to thrive in. Our understanding of how microbial diversity is distributed across natural environments and how microbes affect ecosystems is constantly evolving as public databases are set up and new techniques based on massive sequencing are developed. The microbiome found in a particular anthropogenic environment is generally much less complex than those found in natural ones: there is less competition and the main actors are often linked to survival mechanisms regulated by a few limiting factors. Despite this simplicity, it is very difficult to link cause and effect when seeking to identify the role of individual organisms. In the case of biodeterioration of paper and parchment, even when analysing the individual components of a simple phenomenon, it is not always easy to understand the mechanisms at play. Works of art are unique objects and the elements that determine the arrival and establishment of one or more microorganisms and the direction that the biodeterioration process takes are always different. In some cases, however, there are common denominators and predictable mechanisms. The variables that come into play are examined below.
