LEARNING OUTCOMES

The teaching aims to introduce students to the study of biodeteriogenic fungi living on different types of substrates of artistic and / or historical interest. In addition, the basic tools will be provided for effectively monitoring and controlling such agents with the goal of preserving the cultural heritage.

AIMS AND LEARNING OUTCOMES

The proactive presence of lecturers during the frontal lectures and laboratory activities along with the individual study will allow lecturers:

• to know the morphologic, metabolic, reproductive, trophic, and ecologic characteristics of fungi;
• to distinguish the principal taxa involved in biodegradation cases;
• to individuate the presence of fungi involved in biodegradation processes and to monitor their development;
• to isolate, analyze vital strains and identify fungal agents involved in biodegradation processes;
• to evaluate the main environmental conditions suitable to prevent and/or mitigate the development of fungi involved in biodegradation processes with the aim of a correct conservation-restoration of cultural heritage;
• to select specific protocols for restoration and disinfestation.

PREREQUISITES

To address the contents of the course, general notions of chemistry, general and applied biology are needed.

TEACHING METHODS

The course is organized in 32 hours of frontal lectures and 32 hours of theoretical-applied laboratory. The students are strongly recommended to attend the lectures and laboratory activities.

Each laboratory activity will be proceeded by a short theoretical summary devoted to illustrate the contents, goals and procedures of the work to be performed. At the end of each laboratory, the students will be fill a form (a sort of quiz) devoted to evaluate the acquired skills.

SYLLABUS/CONTENT

Main characters of fungal organisms (including lichenized fungi): structure and ultrastructure, development, differentiation. Sexual and asexual reproduction. Nutrition and trophic characters. General and specific aspects of metabolism. Factors affecting the fungal development.

Criteria for identifying main taxa and with a particular reference to the groups or species involved in biodegradation processes of cultural heritage.

Role of fungi in biodeterioration of different substrate typologies of cultural heritage, in particulary paper biodegradation and foxing. Lichenized fungi involved in deteriorating rocks and stone slate products. Hints of geomycology.

Aerobiology and biomonitoring of fungi.

Laboratory: isolation, cultivation, identification of main fungal agents of biodegradation processes.
