| Abstract:Rubbings are important documents in China， which serve as important carriers of the nation’s cultural history. Therefore， conservation research is of great importance for the long-term preservation of rubbings. In view of the fact that there was a large amount of mold growth in the rubbings of the Zhang Qian Memorial Hall in Chenggu County. In this study the molds were isolated and purified using PDA culture medium. Then， for the scientific identification of the molds， a combination of micromorphological observation and 18S rDNA-ITS sequence analysis was used. The results showed that the predominant mold species found in this batch of rubbings were Aspergillus niger， Trichoderma， Penicillium， and Aspergillus flavus. Different concentrations of nano-ZnO were investigated for their antifungal performance. The macroscopic observation and the microscopic observation based on the scanning electron microscope showed that 2.0% nano-ZnO exhibited effective anti-mold properties on the paper samples. |
