Abstract

[automatically translated] SUMMARY - The degradation of the materials with which the works of art, is often caused by the activity of macro and micro organisms are made (plants, insects, lichens, algae, bacteria, actinomycetes, etc.), called biodeteriogens. Present in all terrestrial habitats, constitute a serious problem for storage both in outdoor sites is confined, such as libraries, archives, mussali institutions, deposits and, anyway, in all those places where it implements storage / use of artifacts. Typically, there is a place for conservation that does not show traces of partial or extensive infestations / colonization involving more or less consistent alterations of the artifacts present. The biological alterations occur with quite different phenomena in relation to organisms to environmental parameters, to the characteristics of the constituent materials of the article. The biodeteriogens can cause chemical damage (related to the effect of metabolic products), physical (related to the penetration of microbial cells or structural parts) and aesthetic (patinas, biofilm). Therefore, it is of fundamental importance to establish the presence of macro-organisms and consequently to characterize them, in order to intervene in a timely manner and effectively limiting the damage, before they become irreversible. In this context, the electron microscopy, both scanning (SEM) that laser scanning confocal (CLSM), is a tool for scientific investigation of extreme interest. ABSTRACT - Works of art are made of such materials That Are Often Subjected to deterioration by macro and micro organisms (plants, insects, lichens, algae, bacteria, actinomycetes, etc ..) called biodeteriogens. They are present in all terrestrial habitats, they Therefore Represent a serious threat for conservation of cultural assets, in Both outdoor and indoor sites, such as libraries, archives, museum institutions, deposits) and all the places where the conservation / use of artifacts is Implemented. Generally, all conservation / fruition sites show signs of either partial or extensive infestation / colonization, Involving the hosted artifacts. Biological systems, strongly related to environmental parameters and characteristics of the constitutive materials, are incendio induces Sufficiently wide range of alterations. The biodeteriogens can cause chemical (related to the effect of metabolic products), physical (related to penetration of microbial cells or structural elements) and aesthetic (coatings, biofilms) damages. Therefore, it is essential to Establish the presence of macro and microorganisms and to identify them in order to promptly and effectively intervene to restrain the damage, before it Becomes irreversible. In this context, electron microscopy, both scanning (SEM) and confocal laser scanning (CLSM) Represent scientific tools of great interest in the diagnostic field.
