“…The tabulated data show the highest catalytic and proteolytic activities were observed by Paecilomyces canoes. These data match those obtained by Pekhtasheva, et al, 2012 [20] proving that during the bio-deterioration of ancient textiles, microorganisms produce extracellular cellulalytic and proteolysis enzymes, as well as secreting pigments and acids. Furthermore, to inhibit all isolated microorganisms, followed by p-chloro-m-cresol at (1000 ppm), and Sodium azide at (2000 ppm).…”

All ancient textile materials have a simple chemical composition, mainly cellulose and protein. This organic component increases the susceptibility of textiles to soaking up and retaining wet from the unfavorable conditions of high humidity and temperature, causing microbial deterioration. Microbial deterioration of archaeological textile was studied as a state from the Egyptian Textile Museum; isolation, purification, and identification of the causative microorganisms were occurring, where the most common microorganisms isolated from archaeological textiles were molds. Biological activities of the isolated microorganisms were studied and disinfection of archaeological textile was applied using different methods. The characteristics of test methods and disinfection include their application to historical objects. Historic textiles were analyzed from different perspectives: Stereo microscopes, SEM with EDX, FTIR, as well as fiber structure and fiber chemical composition. The results illustrated that the best concentrations of a specific mic-robicide for the bio-treatment of infected textile materials is Di-chloroxylenol at (1000 ppm). It is sufficient to inhibit all isolated microorganisms, followed by p-chloro-m-cresol at (1000 ppm) concentration, and Sodium azide at (2000 ppm) concentration.

“…The process of restoring and preserving cultural heritage artifacts needs knowledge of cultural, social and religious life in different old periods of time, requiring multiple and advanced analysis techniques to answer the questions raised by these types of objects [1]. Technical and characterization studies on metal threads from Romanian historical textiles by using modern analytical techniques have been done in our country for more than 15 years [2][3][4][5]. In our study, golden threads from two twin liturgical embroideries: Epitrachelion/ Inv.…”

In the present study, golden threads from two, apparently identical, medieval epitrachelions considered masterpieces of the Romanian Byzantine embroidery art, were investigated by using Micro-Particle Induced X-ray Emission (micro-PIXE) and optical microscopy. PIXE measurements allowed to accurate identify the elemental composition, distribution of the trace elements, the layered structures (depth profiling) and thicknesses of the gold layer. Useful information for the characterization of the gilded silver threads due to elemental maps concerning the constituent elements spatial distribution in the sample was also obtained.
