An integrated approach for assessing the bioreceptivity of glazed tiles to phot...
Coutinho, M. L.; Miller, A. Z.; Martin-Sanchez, P. M.; Mirao, J.; Gomez-Bolea, A.; Machado-Moreira, B.; Cerqueira-Alves, L.; Jurado, V.A laboratory-based methodology was designed to assess the bioreceptivity of glazed tiles. The experimental set-up consisted of multiple steps: manufacturing of pristine and artificially aged glazed tiles, enrichment of phototrophic microorganisms, inoculation of phototrophs on glazed tiles, incubation under optimal conditions and quantification of biomass. In addition, tile intrinsic properties were assessed to...
Técnicas no destructivas para la monitorización cuantitativa y cualitativa de p...
Rogerio-Candelera, M. A.; Miller, A. Z.; Dionísio, A.; Macedo, M. F.; Saiz-Jiménez, C.Biological stone colonisation is one of the main problems related to the conservation of monuments and buildings. Stone biodeterioration has been assessed by several authors using time-consuming and extensive sampling methodologies for microbial identification and the follow-up of their action. However, most sampling procedures may convert the own researchers in deterioration agents. In this study the use of no...
Laboratory-induced endolithic growth in calcarenites: biodeteriorating potentia...
Miller, A. Z.; Rogerio-Candelera, M. A.; Laiz, L.; Wierzchos, J.; Ascaso, C.; Braga, M. A. Sequeira; Hernández-Mariné, M.; Maurício, A.; Dionísio, A.This study is aimed to assess the formation of photosynthetic biofilms on and within different natural stone materials, and to analyse their biogeophysical and biogeochemical deterioration potential. This was performed by means of artificial colonisation under laboratory conditions during 3 months. Monitoring of microbial development was performed by image analysis and biofilm biomass estimation by chlorophyll ...
