Metagenomic and microbiological analyses of historical manuscripts for bacterial community profiling and bacteria-related biodeterioration assessment

March 1, 2026

By documenting both culturable and non-culturable taxa, this work provides a foundational dataset for understanding bacterial contributions to manuscript stability and offers a methodological framework for future research on biodeterioration dynamics in Islamic and global documentary heritage.

Air- and dustborne fungi in repositories of the National Archive of the Republic of Cuba

April 1, 2022

This study has as objectives to determine the concentration and diversity of the air- and dustborne mycobiota in seven National Archive of the Republic of Cuba repositories, and to assess the potential risk of biodeterioration that iso-lated taxa may have. In the indoor and outdoor environmental microbiological samplings a SAS biocollector was used and the indoor/outdoor (I/O) ratio was determined for each repository. The settled dust was collected during six months. Sørensen's coefficient of similarity (QS) was calculated to compare the isolated taxa among the three studied niches (indoor air, dust, outdoor air). The biodegradation potential of the isolated taxa was determined by semi-quantitative tests. The concentrations in the air of repositories with natural cross-ventilation ranged from 225.2-750.3 CFU m-3, while in the Map library with air-conditioning (...)

Murals meet microbes: at the crossroads of microbiology and cultural heritage

December 6, 2021

This article comments on the duality of microorganisms in the conservation and restoration of cultural heritage, which encompasses the negative impact of damaging microorganisms and recent advances in using specific microorganisms and microbial-based technologies for cultural heritage preservation.
