Microbiology
A.Y. 2024/2025
Learning objectives
"This course provides information on microbial deterioration of cultural heritage and
points out critical environmental parameters for proper conservation. The course is an introduction to
biodeteriogens and their identification, prevention and control on different cultural heritage materials.
Finally, the course provides the basic on how to apply microorganisms for the cleaning and consolidation of
cultural heritage surfaces.

cultural heritage surfaces.
Expected learning outcomes
An understanding of how the colonisation and activities of microorganisms in cultural heritage environments affect conservation. The design of acceptable scientific solutions to microbial problems in indoor environments (e.g. museums, libraries and archives), and outdoor environments (e.g. monuments and archaeological sites). The use of microorganisms for cleaning and consolidation purposes.
