Stybio-restoration: microbes for art works
Procedure that uses, either alone or in combination, specific non-pathogenic bacteria, immobilized in an easily applicable and removable gel, for the selective cleaning of deposits, even overlapping, without damaging the paint or the constitutive material of artifacts and without leaving residues. The procedure is harmless and selective and is intended to replace toxic and aggressive products.
In accordance with the latest principles of sustainability in restoration strategy, the invention relates to a bio-cleaning procedure to remove coherent deposits of various nature – even stratified- on different types of artworks, by means of bacterial packs (micro-packs). The bacteria used are spontaneous environmental strains, specifically selected, aerobic, non-pathogenic, conserved in a public microbial collections. The specially prepared laponite gel is a support that allows the bacterial strains to be immobilized, keeping them in the right moisture conditions, it is easy to apply the micro-pack even on vertical surfaces or ceilings and, at the end of treatment, it is easily removable without leaving any residues. The products are non-toxic. The procedure is selective, does not damage the painted patina or the underlying noble patina, is extensible to many problems and “tailor-made” adaptable.
- Bio-cleaning of frescoes, murals and easel paintings (canvas and wood), stone material, paper, intaglio plates;
- Possible extensions: Biodegradation control in substitution of biocidal products for the removal of biological patinas; Bio-consolidation of limestone materials.
- Viable cells do not require controlled operating conditions, unlike enzymes;
- No toxic effects for operators;
- Selective action;
- Safety for the work of art;
- Compatibility with constituent material;
- Environmental compatibility;
- Sustainable “bio-based” economy.
