Biodeterioration of Stone Monuments a Worldwide Issue
The biodegradation is a general action strictly linked in the presence of active organisms, and this is not only unavoidable but it represents a fundamental process of the Biosphere. When this process is acting on « valuable » objects, is named as Biodeterioration. The consequences surely produce a worse condition, and this process is particularly unfavourable when the object belongs to the Cul...
متن کاملWhat About Biofilms on the Surface of Stone Monuments?
Bacteria can live either as free planktonic cells in bulk solution, or as sessile cells attached to a surface. In addition to their attachment status, sessile bacteria are part of sessile communities termed biofilms. A biofilm can be defined as a microbial community attached to a solid surface composed of cells organized as microcolonies embedded in an organic polymer matrix of microbial origin...
متن کاملDiversity of Endolithic Prokaryotes Living in Stone Monuments
Stone monuments (statues, fountains, tombs, memorials, buildings, etc.) are apparently indestructible artefacts that were built to last. Depending on the chemical composition and structure, stones may be friendly or hostile to colonization by eukaryotic and/or prokaryotic communities. Among various lithotypes, porous rocks (limestone, sandstone) have highest bioreceptivity. Abiotic factors have...
متن کاملDesign and testing of artificial stone for the restoration of stone elements in monuments and historic buildings
Different structural parts of monuments and historic buildings were based on stone as the main building material, such as masonry and foundation, while many types of stones were also used for decorative, architectural elements, such as reliefs, cornices, corbels, colonnettes. The preservation of stone elements is crucial for the continuity of these structures. Mortar on the other hand is an art...
متن کاملContributions of in situ microscopy to the current understanding of stone biodeterioration.
In situ microscopy consists of simultaneously applying several microscopy techniques without separating the biological component from its habitat. Over the past few years, this strategy has allowed characterization of the biofilms involved in biodeterioration processes affecting stone monuments and has revealed the biogeophysical and biogeochemical impact of the microbiota present. In addition,...
