Abstract

Wasabi has been displayed substantial fungicidal behavior for the disinfection of bio-deteriorated non-painted archaeological papyri. Therefore, in this study for the first time the interference of Wasabi with different pigments of painted papyrus has been studied. Microbiological, mechanical, physical and chemical evaluations were carried out using various spectroscopic, tensile tester and microscopic tools. Wasabi vapors treatment for 72hs (2.5%) has eradicated the microbial growth of all the examined infected painted and non-painted papyri with inhibition efficiency of 100%. The tensile strength of the treated papyri recorded enhancement by 26%, while maintained the color of painted and non-painted papyri without any noticeable change (ΔE < 1). Moreover, surface morphology of treated papyri has been evaluated and there was no change recorded. Additionally, FT-IR and EDX analyses revealed negligible chemical changes were attained. Interestingly, upon long term treatment evaluation, which has been conducted based on the artificial aging of approximately 100 years, the papyrus samples remained unchanged. Therefore, this study presents a green and cost-effective conservation approach for long-term preservation of painted archaeological papyri.

用 Wasabi 对生物劣化的彩绘考古纸莎草纸进行安全的绿色处理

在对生物劣化的非彩绘考古纸莎草纸进行消毒时，山葵表现出了很强的杀菌能力。因此，本研究首次研究了山葵对彩绘纸莎草纸不同颜料的干扰。使用各种光谱、拉力测试仪和显微镜工具进行了微生物、机械、物理和化学评估。经过 72 小时（2.5%）的山葵蒸汽处理后，所有受感染的彩绘和非彩绘纸莎草纸的微生物生长都被根除，抑制率达到 100%。经过处理的纸莎草纸的拉伸强度提高了 26%，同时保持了涂漆和未涂漆纸莎草纸的颜色，没有发生任何明显的变化 (ΔE<1)。此外，还对处理过的纸莎草纸的表面形态进行了评估，没有发现任何变化。此外，傅立叶变换红外光谱（FT-IR）和乙二胺四乙酸（EDX）分析表明，所发生的化学变化可以忽略不计。有趣的是，根据人工老化约 100 年进行的长期处理评估显示，纸莎草纸样本保持不变。因此，这项研究为长期保存彩绘考古纸莎草纸提供了一种绿色、经济的保护方法。
