“…Hence, the chemistry of minerals and porosity or the shape of the surfaces are important to better understand the biodeterioration mechanisms [37]. Rough and porous surfaces are more vulnerable in facilitating attachment of both airborne propagules and accumulation of nutrient-enriching soiling materials [39]. The biodeterioration process by cyanobacteria has been described previously by Danin and Caneva [38], who highlight how cyanobacteria contribute to the decay of calcareous stones:…”

“…for one year show a significant pH reduction (from 12 to 8) [55]. Biogenic acid production (aggravated by pollutants) and atmospheric weathering act together and create cracks and crevices on concrete surfaces [39]. Fungi increase this physical damage on concrete structures by etching and extending hyphae that penetrate inside surfaces [2,44,54], thus resulting in an enlargement of the already damaged area and an increase in porosity [55], as shown in Fig.…”

“…Under drier conditions, the biofilms are generally grey in colour, whereas more humid areas are more frequently green [2]. Cyanobacteria were found on several materials types: concrete and stones, metals, painted surfaces and plastic [5,26,31,[38][39][40][41]. Table 1 shows the main species isolated from disfigured buildings or those that have been shown to be capable of biodeterioration.…”

“…Painted surfaces are usually smoother and highly exposed to driving rain surfaces, so they remain clearer from colonization [39]. However, there are several studies that show algal fouling of paint films.…”

“…However, there are several studies that show algal fouling of paint films. In general, phototrophic organisms prefer alkaline surfaces more than acid ones, and their growth is encouraged by the presence in the paint of compounds like phosphate and nitrogen, as in latex paints [39]. About the mechanism of erosion on painted surfaces, it seems due to an association between algae and lichens, whose rhizoids can penetrate masonry coatings inducing disruption and detachment of the paint film [44].…”

A strong attention is recently paid to surface properties of building materials as these allows controlling solar gains of the building envelope and overheating of buildings and urban areas. In this regard, deterioration phenomena due to biological aggression can quickly damage solar-reflecting roof surfaces and thus increase sharply solar gains, discomfort, air-conditioning costs and waterproofing degradation. The same deterioration problem has deleterious effect on cultural heritage, ruining its huge historic and artistic value. This work is aimed at providing an overview on the different organisms that affect the surface of most used building materials, to support the design of new building materials with long-lasting surface properties and to find a way to preserve cultural heritage. Artificial ageing is the long-term aim of this investigation, in which what in nature happens after months or years is compressed in a very short time by forcing the growth of microorganisms through a strict control on the different conditioning factors. Both natural and artificial ageing are eventually outlined in the last part of this work to provide a comprehensive idea of what is necessary to study in a complete way biological ageing protocols on building materials. Several characterization techniques are also introduced to analyse the influence of microorganisms on the surface of different building materials.

The study of the physiological action of microorganisms in artistic materials is one of the most interesting topics in biodeterioration nowadays. Pathologies and illnesses of organic and inorganic materials provoked by microorganisms can be treated by experts by a variety of preventive interventions. Artistic medicine encompasses the monitoring of the exhibition and storage of art, as well as proper environmental conditions and the regular cleaning of museums. Biodeterioration control is essential in order to prevent fungal and bacterial contamination in artwork. Biodeterioration of canvas paintings is a complex phenomenon, not well-known at the moment. Canvas paintings are created by several artistic techniques on textile supports that are not always kept in the best conditions, and the best parameters of preventive conservation are often not applied. Therefore, we need to research the agents and the main causes that provoke canvas painting biodeterioration. By applying new methodologies, we can identify the alterations and the treatments needed in order to manage the diverse materials employed in artwork correctly. Herein, we review the causes of biodeterioration that affect artwork, especially art created on textile supports. We also study the alterations of the natural filmogenic materials employed in traditional pictorial techniques, such as agglutinants and protection layers, and the biodeterioration agents that impact them. Additionally, we review current scientific methods employed for the identification of microbial species, and the types of alterations of the materials where the organisms grow. Finally, we summarize the different biocides and preventive conservation treatments that are currently employed.
