Microbial Degradation of Ancient Textiles Housed in the Egyptian Textile Museum and Methods of Its Control

Abstract

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 usage of AgNPs/Klucel G Nanocomposites And Some Conventional Materials in The Conservation of Archaeological Linen Textile Remains

“…Many microbial swabs were taken from the affected surfaces of the archaeological piece by scraping those using sterile medical swabs. [22] Petri dishes containing nutrient media were inoculated with Nutrient Agar bacteria and PDA fungi, and this stage was carried out in a sterilizing UV-type CHEM.TECH sterilization cabin. After the process of inoculating the plates with sterile medical wipes, they were incubated at 28-30 degrees for a period of time of 48-72 hours for Nutrient Agar media for bacteria and 1-7 days for PDA media for fungi.…”
