古旧纸本字画孳生霉斑的鉴定

古旧纸本字画在保存过程中,易于孳生霉菌病害,霉菌会对纸质文物造成不可逆转的破坏作用。为鉴定字画上孳生的霉菌种类,利用分子生物学方法,对馆藏的几幅古旧字画上孳生的疑似霉斑进行分离、纯化、培养、鉴定,鉴定结果确定霉菌有肉色曲霉Aspergillus carneus、草酸青霉菌Penicillium oxalicum、花斑曲霉Aspergillus versicolor、杂色曲霉Aspergullus versicolor、宛氏拟青霉Paecilomyces varioti Bainier、赤散囊菌Eurotium rubrum、产黄青霉Penicillium Chrysogenum、辐毛小鬼伞Coprinellus radians,此鉴定结果可为进一步的霉斑去除以及防霉技术研究提供科学指导。

Identification of the mildew stain on paper of ancient calligraphy and paintings

The paper used in calligraphy and painting relics easily grows paperdamaging mildew during the preservation process. the mildew from paper relics was identified by means of molecular biological methods. Aspergillus versicolor, Aspergillus carneus, Penicillium oxalicum, Paecilomyces varioti Bainier, Eurotium rubrum, Penicillium Chrysogenum, and Coprinellus radians were identfied.The study is valuable for planning antimold treatments for the conservation of paper relics.
