ENZYMATIC MONITORIZATION OF MURAL PAINTINGS BIODETERIORATION
Rosado, Tânia; Martins, M. Rosário; Pires, Margarida; Mirão, José; Candeias, A; Caldeira, A TeresaBiodeterioration of mural paintings by microorganisms is an important research field that needs novel approaches to fully understand the mechanisms and effects. In this work, the presence of microorganisms and their biological activity were investigated by extra and intracellular enzymatic monitorization. The enzymes arylsulphatase, β-glucosidase, dehydrogenase and phosphatase were used as biomarkers of the mic...
Enzymatic systems as biomarkers of cultural heritage decay: A new approach to a...
Pires, Margarida; Rosado, Tânia; Mirão, José; Candeias, António; Martins, M. Rosário; Caldeira, A. TeresaCultural Heritage decay is a serious problem with social and economic impact. Mural painting is one of the artistic expressions widely represented in Portugal, which over the time has suffered numerous forms of deterioration. Heritage decay depends on the physical properties and chemical nature of the materials, several environmental parameters and biological agents. The most harmful organisms involved in biode...
Enzymatic monitorization of mural paintings biodeterioration
Rosado, Tânia; Pires, Margarida; Mirão, José; Candeias, António; Martins, M. Rosário; Caldeira, A. TeresaMural paintings is not only a form of art but also a way of learn more about our ancestral traditions - that´s why it´s so important to protected it from biodegradation. There are several factors that affect this artworks, such as environmental conditions, chemical nature of the substrate and biological agents.
