“…Analyses can monitor the activity of microbiological agents and alterations of artistic support on canvas painting, and on the filmogenic components, thus delimiting each type of organic material and the microorganisms in this support (Agrawal, Dhawan, & Garg, 1989;Bolívar, 1995;Bravery, 1988;Evans, Wales, Bratt, & Sagar, 1992;Gargani, 1968;Gaylarde & Moreno, 2006;Giacobini and Firpi, 1981;Ross, 1963;Strzelczyk, 1981). Other studies deal directly with the nature and composition of the organic materials of canvas paintings, and either focus on the composition of the textile support, or the agglutinants, pigments and protection layers of the pictorial substrate.…”

The study of the physiological action of microorganisms in artistic materials is one of the most interesting topics in biodeterioration nowadays. Pathologies and illnesses of organic and inorganic materials provoked by microorganisms can be treated by experts by a variety of preventive interventions. Artistic medicine encompasses the monitoring of the exhibition and storage of art, as well as proper environmental conditions and the regular cleaning of museums. Biodeterioration control is essential in order to prevent fungal and bacterial contamination in artwork. Biodeterioration of canvas paintings is a complex phenomenon, not well-known at the moment. Canvas paintings are created by several artistic techniques on textile supports that are not always kept in the best conditions, and the best parameters of preventive conservation are often not applied. Therefore, we need to research the agents and the main causes that provoke canvas painting biodeterioration. By applying new methodologies, we can identify the alterations and the treatments needed in order to manage the diverse materials employed in artwork correctly. Herein, we review the causes of biodeterioration that affect artwork, especially art created on textile supports. We also study the alterations of the natural filmogenic materials employed in traditional pictorial techniques, such as agglutinants and protection layers, and the biodeterioration agents that impact them. Additionally, we review current scientific methods employed for the identification of microbial species, and the types of alterations of the materials where the organisms grow. Finally, we summarize the different biocides and preventive conservation treatments that are currently employed.

“…As most of the collagen-based artifacts, leather is frequently involved in bio-deterioration caused by microorganisms (Strzelczyk et al, 1989). The non-adequate environmental conditions of artifacts conservation constitute a crucial factor in the promotion and development of the bio-deterioration favored, in particular, by altered values of temperature and/or relative humidity (Strzelczyk et al, 1987(Strzelczyk et al, , 1997Montanari et al, 2012). The bio-deteriorating agents can cause structural and chromatic alterations inducing hydrolysis of the collagen fibers, modifying the leather's inorganic components, producing pigments, and organic acids causing chromatic alteration or discolouration of the support Piñar et al, 2015a,b;Cicero et al, 2018;Mercuri et al, 2018).…”

Effects of the Ionizing Radiation Disinfection Treatment on Historical Leather

et al. 2020

Microorganisms often cause significant damage on historical objects. The archive or library materials as well as textile or leather artifacts suffer serious attacks that need appropriate care treatments. Several biocide processes have been implemented but often their application does not preserve the material of the good. The objective of this work is the disinfection through ionizing radiation of leather wallpaper from the museum building Palazzo Chigi in Ariccia (Rome, Italy). The controlled sterilization treatments were carried out using X-ray beams to eliminate the microorganisms present on the leather and maintaining unchanged the properties of the constituent material. Some fragments of decorated leather wallpaper, dating back to the 1700s, were irradiated with X-rays up to 5,000 Gy. The amount of microorganisms was evaluated by microbiological analysis before and after X-ray irradiation treatments to identify the dose that inhibits the bacterial load. It will be shown how the results obtained by the application of different chemical-physical techniques (Scanning Electron Microscopy, Fourier Transform Infrared spectroscopy and Light Transmission Analysis) have helped in the evaluation of the impact of the X-rays on leather chemical and physical integrity.

“…Pigments and colored spores are produced as the molds grow on wood surfaces resulting in wood discolorations (Viitanen and Ritschkoff, 1991;Ghosh et al, 2008), and distortion of wood could take place without affecting its strength (Daniel, 2003). Decayed bookbinding leather showed the prescience of C. globosum as a very active organism (Strzelczyk et al, 1987).…”

Assessment of efficacy and effectiveness of some extracted bio-chemicals as bio-fungicides on wood

2019

The present study investigates in-vitro the antifungal activity of two extracts (ethyl ether extracts of Schinus terebinthifolius ripened fruits and Pinus rigida heartwood) and two essential oils (Thymus vulgaris and Origanum majorana leaves) against two species of fungi; Trichoderma harzianum and Aspergillus niger. The results clearly show that O. majorana oil and P. rigida wood extract had the highest activity against both fungi and were chosen for the application on four wood species; Weeping-Wreath Wattle (Acacia saligna), Beech (Fagus sylvatica), Black Walnut (Juglans nigra) and Pitch Pine (Pinus rigida). Additionally, their impact on the wood structure was examined by FTIR, SEM and colorimetry. The study suggests that O. majorana oil appears to show the best results and could be used as friendly bio-fungicides to protect wood objects without changing their structures.
