“…SSA is directly related to porosity and inversely related to pore size (Benavente et al, 2007;Benavente, 2011) and therefore, provides pore structure information related to decay mechanisms. Thus, high SSA values imply a high susceptibility to salt weathering (Benavente et al, 2007), capillary stress (Benavante et al, 2008), high capacity to water condensation and retention within porous materials, and consequently, high bioreceptivity (Sanchez-Moral et al, 2005;Miller et al 2012). In addition, the presence of a water film might decrease the free surface energy of the material, decreasing its strength.…”

The Circular Mausoleum in the Roman Necropolis of Carmona was carved on a calcarenite sequence in an ancient quarry located in the town of Carmona, Southern Spain. This rock-cut tomb, representative of Roman burial practices, currently suffers from serious deterioration. A detailed survey over several years permitted the identification of the main tomb's pathologies and damaging processes, which include loss of material (scaling, flaking, granular disintegration), surface modifications (efflorescences, crusts and deposits) and extensive biological colonization. The results obtained in this study indicated that anthropogenic changes were largely responsible and enhanced the main alteration mechanisms observed in the Circular Mausoleum. Based on the deterioration diagnosis, effective corrective actions were proposed. This study shows that any conservation intervention in the interior of the tomb should be preceded by accurate in situ measurements and laboratory analyses to ascribe the source of the deterioration damages and thus designing effective treatments.

“…It is well known that rocks, either in natural geological settings or as part of monuments, are common habitats for a wide range of microorganisms (Scheerer et al, 2009;Miller et al, 2012). The colonization of lithic substrates by microbial communities is influenced by the properties of the substrate, such as porosity, surface roughness and mineralogical composition -bioreceptivity-(see review in Miller et al, 2012), in addition to climate and microclimatic conditions (Guillitte, 1995;Ortega-Morales et al, 1999;Gaylarde and Gaylarde, 2005;Barberousse et al, 2006).…”

Antecedentes y Objetivos: La colonización de los sustratos líticos por comunidades fúngicas está determinada por las propiedades del sustrato (bioreceptividad) y las condiciones climáticas y microclimáticas. Sin embargo, los efectos del tiempo de exposición de la superficie de la roca calcárea al ambiente sobre la composición de las comunidades fúngicas no se ha investigado. En este estudio, analizamos la composición y estructura de las comunidades fúngicas inmersas en biopelículas asociadas a roca calcárea, en paredes de edificaciones modernas construidas a diferentes tiempos en un ambiente subtropical en Campeche, México.Métodos: Se consideró una cronosecuencia de paredes construidas a uno, cinco y 10 años. Sobre cada pared, se rasparon tres superficies de 3 × 3 cm para cada biopelícula. Los hongos se aislaron por la técnica de lavado y filtración de partículas, posteriormente se inocularon en dos medios de cultivo contrastantes (un medio oligotrófico y uno copiotrófico). Los hongos se identificaron de acuerdo a sus características macro y microscópicas.Resultados clave: Encontramos 73 géneros y 202 especies de 844 aislados. Los resultados mostraron que las comunidades fúngicas son diferentes en las tres biopelículas. En la biopelícula de desarrollo intermedio encontramos un alto número de aislados, pero tanto la riqueza como la diversidad fueron bajas. En contraste, en la biopelícula avanzada, los valores de riqueza de especies y diversidad fueron altos, y las especies abundantes fueron Hyphomycete 1, Myrothecium roridum y Pestalotiopsis maculans. Las especies dominantes en la biopelícula intermedia fueron Curvularia lunata, Curvularia pallescens, Fusarium oxysporum y Fusarium redolens, y en la biopelícula joven fueron Cladosporium cladosporioides, Curvularia clavata, Paraconiothyrium sp. y Phoma eupyrena.Conclusiones: Nuestros resultados sugieren que la composición de la comunidad fúngica en cada biopelícula cambia de acuerdo al tiempo de exposición de la roca calcárea al ambiente. Además, como parte de la composición de la comunidad fúngica, encontramos un conjunto de especies poco comunes que podrían ser autóctonas en la roca calcárea.

“…There may be additive biodeteriorative effect of the other microorganisms like cyanobacteria and etc., but we didn't searched its. Similar researches demonstrated that cyanobacteria is a component of stone deteriotation [4][5][6][7][8]21,24,25].…”

“…The stone is susceptible to colonization by several microorganisms such as bacteria, fungi, algae, cyanobacteria and more complex organisms such as lichens and mosses responsible for a series of mechanical and chemical processes that cause the biodeterioration of the stone. The relative effects of each of these organisms vary according to the topoclimatic environmental conditions, the stone type, its state of preservation and its position on the monument [6][7][8]. On the other hand, pore size, distribution and specific surface area together with the capillarity of a stone control the mechanical degradation caused by water, salts, and bacteria.…”

“…In addition to physical and chemical factors, microorganisms play a contributing role in deterioration of stone monuments [4,13]. Microbial colonization of buildings causes aesthetic and physical damage to the structure through the formation of biofilms, which contain microorganisms and their metabolic products, such as extracellular polymeric materials (EPS), and both inorganic and organic acids [7,14,15].…”
