“…As regards historical or ethnographic textiles, glues have mainly been used for restoration purposes, e.g. to fasten them to textiles or to solid (paper or wood) supports (Ahmed and Kolisis 2011). In the past, glues of either vegetal (i.e.…”

“…In the case of animal glues, humidity, temperature, UV radiation and pollutants can generate protein cross-linking and/or hydrolysis/oxidation of peptide bonds, while microbial metabolism produces acid molecules and pigmented spots (Barbabietola et al 2016). Starch glue has been commonly used for ancient textile restoration (Ahmed and Kolisis 2011;Whaap 2007). After aging, starch paste is generally found in shrunk, cracked, rigid and brittle form, which cannot provide enough adhesion for effective support.…”

“…Bio-based methods, i.e. the use of enzymes or microorganisms, have been shown to be a very efficient alternative in a number of cases (Ahmed and Kolisis 2011;Barbabietola et al 2016;Ferrari et al 2017).…”

“…Enzymes are certainly the most frequently used method for the treatment of glue-damaged paper (Banik et al 2003;Corbi et al 2005;DeSantis 1983;Sandrine 2002) or textiles (mainly linen, silk and cotton fabrics, so far) (Ahmed and Kolisis 2011;Ciatti et al 2010) and several successful examples have been reported in the literature. For instance, trypsin has been used for detaching a compact block of leaves (Wendelbo 1976).…”

Ancient documents and milestones of human history such as manuscripts and textiles are fragile and during aging undergo chemical, physical, and biological deterioration. Among the different causes of damage, also human intervention plays a role since some restoration strategies proved to be transient and/or they generated further damage. Outdoor monuments undergo deterioration since they are exposed to pollution, weathering, microbial attack (giving rise to undesired pigmentation, discoloration or true dissolution, corrosion, and overall decay), as well as man-made damage (i.e., graffiti). This review article reports the best-fitting strategies used to restore wall paintings, outdoor monuments, textiles, and paper documents to their ancient beauty by employing "soft" biobased approaches such as viable bacteria or suitable enzymes.

“…Adhesives, both natural and synthetic, are widely used in the restoration practice, yet in many cases their aging produces aesthetic alterations, or the formation of volatile and acidic compounds that are detrimental to the artefacts [1][2][3]. Following their invention in 1845 (attributed to Dr. Horace Day) for medical purposes, pressure sensitive tapes (PSTs) were industrially developed in the 1920s, and largely exploited in different applicative fields [4].…”

Ancient textiles are fragile and several factors can affect their integrity. In the present chapter, the main agents of deterioration of old and new textiles, namely physical-chemical (light, oxygen, heat, and humidity) and biological factors as well as human erroneous interventions will be explored. As far as the biological deterioration is considered, the effects of microbial growth, primary and secondary metabolites (acids, solvents, surfactants, pigments) and enzymes (lipases, proteases, and glycosidases) on textile strength and cleanliness will be described in details. The main fungal and bacterial species involved in the damage (textile discoloration, black and green spots, cuts) will be reported. Adhesive application during restoration procedures is discussed to highlight the risk of glue thickening giving rise to dull precipitates on the fabric.The main strategies for oil-stain and glue removal (both animal glue, such as fish collagen, and vegetal glue, i.e. starch) will be described in the paragraph devoted to biorestoration. Finally, a case study concerning an ancient Coptic tunic housed in the Egyptian Museum of Torino, Italy, and biocleaned by means of gellan-immobilized alpha-amylase from Bacillus sp. will be largely discussed by reporting historical data, adhesive characterization, methods for artificial aging of simulated sample and glue removal from the artwork.
