| Abstract:This study took the collection of “Characters on paper” in Shaanxi History Museum as the research object to discuss the removal of mildew. On the basis of the analysis of the pigment components of this heavey color painting and calligraphy， the species of mildew on the surface of the painting and calligraphy were separated， purified and identified， and the simulated samples of mineral pigment and non-mineral pigment mildew were made by using the successfully cultivated strains. Four cleaning solutions， 75% alcohol cleaning solution， 3% papain cleaning solution， 3% papain and 0.05% ascorbic acid compound cleaning solution， and 3% papain and 5% betaine compound cleaning solution were used to clean mildew. The results showed that the cleaning solution combined with 3% papain and 5% betaine compound cleaning solution had a good cleaning effect on the non-mineral pigment mold samples， and had less impact on the color difference， gloss， pH value， and physical properties of mineral and non-mineral pigment heavy-colored paper samples. Therefore， it could be used for cleaning mold stains produced by Aspergillus glaucus. |
