Growth of phototrophic biofilms from limestone monuments under laboratory condi...
Miller, Ana Zélia; Laiz, Leonila; Dionísio, Amélia; Macedo, Maria Filomena; Saiz-Jimenez, CesareoInternational Biodeterioration & Biodegradation,xxx (2009) 1–8 ; In the current study, five phototrophic biofilms from different Southern Europe limestone monuments were characterised by molecular techniques and cultivated under laboratory conditions. Phototrophic biofilms were collected from Orologio Tower in Martano (Italy), Santa Clara-a-Velha Monastery and Ajuda National Palace, both in Portugal, and Sevil...
Biodiversity of cyanobacteria and green algae on monuments in the Mediterranean...
Macedo, Maria Filomena; Miller, Ana Zélia; Dionísio, Amélia; Saiz-Jimenez, CesareoMicrobiology (2009), 155, 3476–3490 ; The presence and deteriorating action of micro-organisms on monuments and stone works of art have received considerable attention in the last few years. Knowledge of the microbial populations living on stone materials is the starting point for successful conservation treatment and control. This paper reviews the literature on cyanobacteria and chlorophyta that cause deteri...
The influence of inherent properties of building limestones on their biorecepti...
Macedo, Maria Filomena; Miller, Ana Zélia; Dionísio, Amélia; Laiz, Leonila; Saiz-Jimenez, CesareoAnnals of Microbiology, 59 (4) 705-713 (2009) ; The influence of open porosity, water absorption capillarity, water vapour permeability, surface roughness, stone pH and chemical composition on stone bioreceptivity to phototrophic microorganisms was assessed by means of a thorough stone characterisation with subsequent artificially inoculation of limestone samples with a multi-species phototrophic culture and p...
Reproducing stone monument photosynthetic-based colonization under laboratory c...
Macedo, Maria Filomena; Miller, Ana Zélia; Laiz, Leonila; Miguel Gonzalez, Juan; Dionísio, AméliaScience of the total environment 405(2008) 278-285 ; In order to understand the biodeterioration process occurring on stone monuments, we analyzed the microbial communities involved in these processes and studied their ability to colonize stones under controlled laboratory experiments. In this study, a natural green biofilm from a limestone monument was cultivated, inoculated on stone probes of the same lithot...
