“…Sulphur and nitrifying bacteria have been linked to deterioration of concrete, and are thus capable, by their biological activity, of generating the same acids which may be present in acid rain. However, Tiano et al (1975) stated that no relation was observed between the number of sulphur-oxidizing bacteria and the gypsum content of weathered stones. Sulphur oxides, major pollutants in urban environments, play a key role in the formation of gypsum crusts covering the surfaces of weathered limestones (Saiz-Jimenez and Bernier, 1981;Del Monte et al, 1984;Grimalt et al, 1991;SaizJimenez, 1993).…”

“…These organisms, from which sulphur and nitrifying bacteria are representatives, are rare in nature, and their share in the total production of organic matter is small. Microbiological analyses of weathered stones have shown the presence of microorganisms which utilize sulphur dioxide or sulphurcontaining compounds giving rise to sulphate as a product of metabolism (Tiano et al, 1975). Species of the genus Thiobacillus utilize hydrogen sulphide, elemental S and even thiosulphate as sources of energy for carbon dioxide reduction.…”

Monuments and buildings act as repositories of airborne organic and inorganic pollutants, which accumulate at the surfaces in zones protected from direct rainwater. This enriches the substratum and anthropogenic compounds may influence to a great extent the colonization and growth pattern of microorganisms in polluted urban environments. This paper reviews recent and ongoing research on the deposition of pollutants on building stones and their possible utilization by microorganisms.

“…In these positions, different groups of organisms can settle and spread on and into the rock materials. Biodeterioration research has so far focused chiefly on lichens, fungi, algae and bacteria in Europe and the Mediterranean (Tiano et al 1975;Nimis and Monte 1988;Tretiach 2004). Microorganisms living on inorganic substrates form more or less complex communities structured in biofilms, or microbial mats (Tomaselli 2003).…”

The problem of deterioration of art works is particularly relevant in countries like Iran that are rich in cultural heritage. According to UNESCO data, Iran holds the tenth rank in a list of countries possessing the highest number of monuments belonging to the world cultural heritage. Archaeological areas, buildings, mosques, statues, museums and objects are all exposed to different biogenic and abiogenic stresses under generally aggressive climatic conditions. Lichens and fungi are known to actively decompose stone surfaces. This process is both physical and chemical in nature and often reaches deep below the stone surfaces. This is caused by chemical and physical interactions of the microbiota with the fluctuating and often drastically changing environmental conditions. Here, we describe and analyze the mainly physical degradation by invading fungal hyphae between stone crystals and a generally destabilizing stone texture. In addition to physical deterioration, organic acids produced by lichens enhance the chemical decomposing processes. In this work, penetration of hyphal bundles as well as individual fungi was studied, and the biodeteriorating patterns were documented and compared to general physical-chemical weathering phenomena. Several strains of aggressive black yeast-like fungi and bacteria were isolated and cultivated and will be described in a taxonomical context with many other isolates from different localities using physiological, morphological and molecular data.

“…The most abundant bacterium was Micrococcus luteus, but species of the genera Bacillus, Pseudomonas, and Streptomyces were also identified. Sulphur oxiding and reducing bacteria in amounts exceeding those indicating biological attack to monuments (Tiano et al, 1975) were recorded.…”

Abstrad:The weath.ering of stone and masonry results, among other phenornena, in the formation of effiorescences, a deposit of salts not originally evident in the sound material, and composed of a variety of different hygroscopic salls, including carbonates, chlorides, nitrates, sulphates, etc. Thus the deteriorated areas of sorne monuments can be considered as extremely saline environments, at least in the effiorescences zones. These zones seemed to be a particular niche for investigating halotolerant and/or halophilic bacteria, but only recently a few reports appeared stressing the importanee ofthese types ofbacteria. In this paper, bacteria were isolated from samples taken from the effiorescences originated in the Chapel of AH Souls, cathedral of Jere~ Spain, and cultured in media with increasing concentrations ofhalite" or epsomite (up to 25 %). The most frequently isolated genus waS Baci/lus, followed by Staphylococcus, Kocuria, Micrococcus, Paenibaci/lus and Arthrobacter. The origin, occurrence and ecology ofhalotolerant and halophilic bacteria in monuments are discussed.
