Historical textiles – a review of microbial deterioration analysis and disinfection methods

All historical textile materials, due to their chemical composition (cellulose, protein), under conditions of high humidity are potentially exposed to microbial degradation. Numerous examples of microbial deterioration of archaeological textile materials demonstrate the need for the use of modern analytical methods for examination of diversity of organisms inhabiting them, as well as an analysis of their behavior. It is recommended that objects with a high degree of microbiological contamination are disinfected before being incorporated to a collection. Today, due to the progress in research on the effects of disinfection on historical material, risks to health and the environment, new methods of disinfection are still being developed. The presented literature review describes the testing methods of microbial deterioration of historical textile materials, including the latest methods for assessing biodiversity (called Next Generation Sequencing) and properties of historical textiles (chemical, microscopic, mechanical). It is particularly suitable for conservators and scientists who are interested in biodeterioration, disinfection technology, and maintenance problems of this type. Characteristics of test methods and disinfection include their application to historical objects, description, advantages, and disadvantages, as well as directions for future studies that aim to even better protect cultural heritage using the latest scientific and technical innovations.
