Fungal Inhabitants of Deteriorated Historical Manuscripts at Istanbul University’s Virtual Library: Comparative Sampling and Media Assessments
Abstract
Historical manuscripts are invaluable cultural artifacts whose preservation is crucial for safeguarding human heritage. This study investigated fungal contamination in twenty-five deteriorated paper-based historical manuscripts from the Istanbul University Virtual Library. Samples were collected using both swab and membrane filter methods, and fungal isolates were cultivated on dichloran glycerol 18 agar and malt extract agar. Cellulase activity was screened among isolates, followed by morphological identification. A total of 199 fungal isolates were obtained, 93.46% of which were cellulolytic, and their enzymatic indices ranged from 1.16 to 4.00. Swab sampling yielded significantly higher colony counts than membrane filtration, although no significant difference was found between media. The most frequently encountered species were Penicillium chrysogenum and Aspergillus fumigatus. The findings emphasize the necessity of using complementary sampling techniques and culture media to assess microbial diversity and enzymatic activity in historical documents, thereby informing more effective conservation strategies.
