“…In order to establish the impact of the biocleaning on the treated surfaces, color variation, mineralogical and chemical analyses were carried out to evaluate the nitrate removal and to monitor the long term effects on the surface. Nitrate removal was successful and six years later, in the areas that had been treated using bacteria, the nitrate concentration remained stable; no noteworthy presence of microflora or color change were measured in comparison with an untreated control area [11].…”

Abstract:Microbial agents are among the major causes of deterioration of cultural heritage, strongly affecting our global cultural legacy, the stone, glass, wood and other sources used to fabricate millions of artworks and monuments around the world. However, it is not all about rotting and erosion! Microbial action has been harnessed to clean the surfaces of stone sculptures and buildings and frescoes. In particular, the ability and potential of different microorganisms to remove undesired sulphates, nitrates and organic matter have been demonstrated a number of times in the last decade.

The collaboration between scientists and conservators is fundamental for achieving reliable and durable results in the conservation of works of art. The contribution of scientists lies in the development of both advanced diagnostic techniques and cutting-edge materials for the restoration of artifacts. Colloid and materials science have provided over the last decades a palette of tools for the cleaning, consolidation and pH control of artistic and historical substrates. Nanostructured materials such as microemulsions, micellar solutions, dispersions of alkaline nanoparticles and chemical gels, can be used to effectively counteract the degradation processes without altering the physico-chemical properties of the treated works of art, and to minimize or completely avoid drawbacks. This chapter provides an overview of the principles and scopes that underlie the use of nanomaterials in conservation science, considering the advantages with respect to traditional restoration materials, and the availability of these innovative tools.
