Sažetak
Throughout the history of Zadar's cultural heritage conservation facilities as private libraries and archives, they have collected a huge amount of diverse material, among which a significant part consists of old and rare books, manuscripts, and archival documents. Cultural heritage is one of the most important components of cultural identity, which is why its preservation, research, and presentation are national priorities. Since all types of material cultural heritage are subject to biological decomposition, it is necessary to study fungal communities that can colonize and decompose them to adopt optimal prevention and conservation strategies. One of the most important causes of microbiological deterioration of book cultural property is molds. Mold spores can be found in air and dust and, under favorable conditions, begin to grow after coming into contact with the book material. They can cause significant damage by secretion of cellulolytic, ligninolytic, and proteolytic exoenzymes. Cellulolytic enzymes degrade cellulose to glucose monomers and thus cause paper degradation. To prevent mold contamination or treat already contaminated items, an integrated approach that includes (micro) climate control, material-specific cleaning, and the application of carefully selected fungicides is needed. Monitoring biological air contamination is crucial for assessing the level of contamination and the potential risk to the preservation of cultural heritage and is the first step toward a successful prevention strategy. Moreover, the goal and purpose of the preventive approach are to prevent the biological degradation of cultural assets in case of the presence of cellulolytic molds to prevent the risk of biodegradation of cultural heritage. Therefore, within the project "KultBaMikroo", the monitoring of cellulolytic fungi in the air on the premises of the State Archives and the Archbishop's and Kaptol Library in Zadar has begun. Air sampling was performed using the device "Air Sampler" MAS-100NT, the air was passed through sterile nutrient media in Petri dishes. At each sampling point, three types of nutrient media were used to cover a wider range of fungi living at different relative humidity. The first preliminary results of the research showed us the number of colonies, the presence, diversity, and dynamics of cellulolytic fungi in the air on the premises of the Archbishop's and Kaptol's Library and the State Archives.
