Colored microbial coatings in show caves from the galapagos islands (Ecuador): ...
Miller, Ana Zélia; García-Sánchez, A.M.; Coutinho, M.L.; Pereira, M.F.C.; Gázquez, F.; Calaforra, J.M.; Forti, P.; Martínez-Frías, J.; Toulkeridis, T.The Galapagos Islands (Ecuador) have a unique ecosystem on Earth due to their outstanding biodiversity and geological features. This also extends to their subterranean heritage, such as volcanic caves, with plenty of secondary mineral deposits, including coralloid-type speleothems and moonmilk deposits. In this study, the bacterial communities associated with speleothems from two lava tubes of Santa Cruz Island...
Biodeterioration of glass-based historical building materials: An overview of t...
Macedo, M.F.; Vilarigues, M.; Coutinho, M.L.The main goal of this work was to review the 21st century literature (2000 to 2021) re-garding the biological colonisation and biodeterioration of glass-based historical building materials, particularly stained glass and glazed tiles. One of the main objectives of this work was to list and systematize the glass-colonising microorganisms identified on stained glass and glazed tiles. Biodiversity data indicate th...
A transparent dialogue between iconography and chemical characterisation: a set...
Rodrigues, A.; Coutinho, M.L.; Machado, A.; Martinho, B.A.; Cerqueira-Alves, L; Macedo, M.F.; Vilarigues, M.This work presents the first results of the iconographic study and analytical characterisation of a set of four stained-glass panels that are part of the collection of National Palace of Pena (Sintra, Portugal). These panels were collected by the King Ferdinand II in the mid-nineteenth century, for his main residence the Palace of Necessidades (Lisbon, Portugal), and only first presented to the general public i...
Biodeterioration of majolica tiles by the fungus Devriesia imbrexigena
Coutinho, M.L.; Miller, A.Z.; Phillips, A.; Mirão, J.; Dias, L.; Rogerio-Candelera, M.A.; Saiz-Jimenez, C.; Martin-Sanchez, P.M.; Cerqueira-Alves, L.This study aimed at evaluating the influence of ageing on the bioreceptivity and biodeterioration of glazed tiles by fungi. These microorganisms have been identified in historical tile colonizing microbial communities. A 12-month laboratory colonization experiment was conducted using pristine and artificially aged tile models inoculated with Devriesia imbrexigena. Fungal growth was evaluated by digital image an...
