Mould and yeast identification in archival settings: preliminary results on the...
Pinheiro, A. C.; Macedo, M. F.; Jurado, V.; Saiz-Jimenez, C.; Viegas, Carla; Brandão, J.; Rosado, L.This project was developed to fully assess the indoor air quality in archives and libraries from a fungal flora point of view. It uses classical methodologies such as traditional culture media – for the viable fungi – and modern molecular biology protocols, especially relevant to assess the non-viable fraction of the biological contaminants. Denaturing high-performance liquid chromatography (DHPLC) has emerged ...
Manganese oxides as biominerals in a granitic subterranean environment
Miller, A.; Dionísio, A.; Braga, M. A. Sequeira; Afonso, M. J.; Jurado, V.; Fernandez-Cortes, A.; Cuezva, S.; Sanchez-Moral, S.; Saiz-Jimenez, C.Black coatings were detected on granite surfaces in groundwater catch work tunnels from Porto city (NW Portugal). XRD, FTIR, Micro-Raman, ICP-MS, TEM-EDS, SEM-EDS and SEM-FIB were the analytical procedures carried out to investigate the origin of the black coatings. In this subterranean environment, the enrichment in metals and other trace elements, such as Mn and Fe, and clay minerals characterize the black mi...
