摘要:

目的:对带有“霉斑”的纸质文物上的霉菌进行分离鉴定并优化其培养条件。方法:通过形态学观察(三点植入法、镜下显微结构观察法)与分子生物学18S rDNA ITS序列扩增相结合对纸质文物上霉菌进行鉴定,采用单因素分析及正交试验对霉菌培养条件进行优化。结果:两种方法的鉴定结果均显示该菌株为链格孢霉菌(Alternaria eichhorniae),其培养最佳条件为28℃,pH 5.5,摇床震荡频率125 r/min。结论:确定该菌为链格孢霉菌(Alternaria eichhorniae),其培养条件实验室较易达到,为下一步纸制文物上的霉斑成份分析及生物法清洗霉斑的研究奠定基础,并为纸质文物上霉菌防治提供科学依据。

Objective: To isolate and identify the fungus on paper heritage as well as optimized culture condi-tions. Method: Through morphology (three implantation, microscopic observation microstructure) and Molecular Biology 18S rDNA ITS sequence amplification a strain on the paper relics is identified. The fungal culture condition is optimized by using single factor analysis and orthogonal test. Results: Two identified results showed that it was a strain of Alternaria mold (Alternaria eichhorniae). The optimum for its cultivation conditions is 28˚C, pH 5.5, shaking frequency 125 r/min. Conclusion: The strain is identified as a Alternaria mold (Alternaria eichhorniae) whose culture condition is easier to achieve in our laboratory, which makes basis for further analysis of components of mildew on paper artifacts and cleaning mildew with biological research, and also provides scientific basis for prevention and treatment of mold on paper artifacts.
