Cultural property preserved in indoor environments is subjected to fungal deterioration which resulted from air biocontamination and can lead to a heavy cultural loss. This study aimed to monitor and assess the biodiversity and concentration of airborne fungi for all areas of the Grand Egyptian Museum—Conservation Center (GEM-CC), such as conservation laboratories, scientific laboratories, corridors, storerooms, and outside in each season during 2013 using the air sampler machine. Results of the quantitative analysis of fungal aerosol demonstrated that the air quality level in GEM-CC was generally acceptable, though some areas showed deviation from the threshold limit value of the GEM-CC (200 CFU m−3). Also, the fungal load in all storerooms was lower than inside the laboratories. Quantitative analysis revealed that 22 fungal species were isolated and identified. The genus Penicillium appeared with high relative distribution (42.6%), followed by Cladosporium and Aspergillus. In vitro study revealed the effectiveness of ethanol with 70% concentration, against the most common airborne fungus: Aspergillus flavus. However, the concentration rose to 95% when applying in vivo. Finally, we suppose that weekly spraying the GEM-CC environment with 95% ethanol is a protective measure for both our valuable artifacts and staff health.

大埃及博物馆—保护中心空气菌群监测方法与控制建议

保存在室内环境中的文化财产会受到空气生物污染导致的真菌退化，并可能导致严重的文化损失。本研究旨在监测和评估 2013 年每个季节大埃及博物馆保护中心 (GEM-CC) 所有区域的空气传播真菌的生物多样性和浓度，例如保护实验室、科学实验室、走廊、储藏室和室外使用空气采样器。真菌气溶胶的定量分析结果表明，GEM-CC 的空气质量水平总体上是可以接受的，尽管有些地区表现出与 GEM-CC 阈值限值（200 CFU m-3）的偏差。此外，所有储藏室的真菌负荷都低于实验室内部。定量分析表明，分离和鉴定了 22 种真菌。青霉属的相对分布较高（42.6%），其次是枝孢属和曲霉属。体外研究揭示了 70% 浓度的乙醇对最常见的空气传播真菌：黄曲霉的有效性。然而，在体内应用时，浓度上升到95%。最后，我们假设每周用 95% 乙醇喷洒 GEM-CC 环境是对我们宝贵的文物和员工健康的保护措施。体内应用时浓度升至95%。最后，我们假设每周用 95% 乙醇喷洒 GEM-CC 环境是对我们宝贵的文物和员工健康的保护措施。体内应用时浓度升至95%。最后，我们假设每周用 95% 乙醇喷洒 GEM-CC 环境是对我们宝贵的文物和员工健康的保护措施。
