“…Geba et al [ 63 ] claimed that increasing the irradiation dose above 10 kGy had drastic effects on the loss of elasticity and the mechanical resistance of the tested specimens. In another study on fabrics (wool, linen, silk, and cotton), it was proven that all specimens became discolored by exposure to gamma irradiation from 0.5 to 25 kGy, and this change in darkness was more evident in samples dyed with natural pigments [ 64 ].…”

The microbial deterioration of cultural heritage includes physical and chemical damage as well as aesthetic alteration. With the technological advancement, a plethora of techniques for removing unwanted microorganisms have opened up new opportunities for microbiologists and conservators. This article reviews the most applied, up-to-date, and sustainable techniques developed for the control of cultural heritage microbial deterioration presenting noteworthy case studies. These techniques include chemical methods, i.e., traditional biocides and nanoparticles; physical methods, such as mechanical removal, UV irradiation, gamma radiation, laser cleaning, heat shocking, microwaves, and dry ice treatment; and biological methods, such as natural molecules with biocidal activity, enzymes, and microorganisms. The application of control systems requires the comprehension of their behavior toward the unwanted microorganisms and possible interactions with the heritage materials. This overview shows also the control methods drawbacks for the purpose of creating awareness in selecting the most suitable technique or combination of techniques.

“…These methods dislodge or cause the lysis of some microorganisms with the help of tools, such as brushes (Caneva et al 1991;Borderie et al 2015). In contrast to biocides, the killing does not lead to resistance but the material can be discolored or damaged (López et al 2010;Vujcic et al 2019). Additionally, the effect is mainly on the surface, e.g., endolithic growth is generally not affected.…”

Microorganisms in the Deterioration and Preservation of Cultural Heritage

View full text Add to dashboard Cite

Subaerial biofilm (SAB) formation on cultural heritage objects is often considered an undesirable process in which microorganisms and their by-products, e.g., enzymes and pigments, cause damage or alteration to a surface. Since biofilms are widespread phenomena, there has been a high demand for preventive and control strategies that resist their formation or reduce their negative effects once formed. Up to date, the main strategy to control biofilms has been the use of biocides. Because of their intrinsic properties, biocidal products can pose risks to humans, animals, and the environment. In this chapter, the authors call “green” only those alternative strategies to biocides able to prevent/control biofilms but that do not kill microorganisms, i.e., irrespective of the use of natural compounds. Here, we describe some of the methods that are most commonly used to test the effectiveness of antibiofilm compounds with multiple-species biofilm model systems. A unified terminology and well described protocols and guidelines are still required to compare and test the effectiveness of traditional or novel compounds against biofilms retrieved on heritage surfaces.

“…[14][15][16] Also, to lower down the environmental impacts associated with utilization of synthetic dyes, natural dyes have widely been explored by researchers all over the world. Currently researchers are working on finding the new sources of natural dyes, cleaner extraction process, eco-friendly mordent, [17,18] also improved natural dyeing (better exhaustion and fixing) of textiles with use of advanced treatment such as nonthermal plasma, [17,19,20] microwave processing, [21,22] ultrasonic processing, [23] gamma ray irradiation [24] etc., apart from enzymatic pre-treatment.…”
