监测空气传播真菌的动态和控制有害真菌对文物保护至关重要。然而,空气质量和微生物群落结构特征的评价,尤其是真菌,尽管中国建设了4000多个档案馆,但档案氛围正处于不断探索的阶段。本研究从昆明医科大学档案馆采集了72个不同空间和天气条件下的空气样本,位于昆明都市圈,云南省,中国西南部。总共22个空气传播的真菌类别,确定了160个属和699个ASV,随着外部空间空气流通的加强,物种多样性正在增加,因此,在窗户和晴朗天气的空间中发现了密集的能量代谢和活动,除了室内样品的脂质合成高于室外样品。此外,晴天和多雨天气之间的真菌群落组成和丰度存在显着差异。在档案的各种环境和天气条件下,已经确定了相当多的物种作为指标,温度和湿度被认为与这些物种的丰度具有显着相关性。同时,枝孢菌和链格孢菌是这里的优势属,这可能对档案专业人员的健康构成威胁。因此,监测和控制这些真菌物种的生长对于保存纸质记录和档案专业人员的健康至关重要。
Monitoring dynamics of airborne fungal species and controlling of harmful ones are of vital importance to conservation of cultural relics. However, the evaluation of air quality and the community structure characteristics of microorganisms, especially fungi, in the atmosphere of
archives is in a stage of continuous exploration though more than 4,000
archives were constructed in China. Seventy-two air samples were collected in this study under different spatial and weather conditions from the
archives of Kunming Medical University, located in the Kunming metropolitan area, Yunnan province, southwestern China. A total of 22 airborne fungal classes, 160 genera and 699 ASVs were identified, the species diversity is on the rise with the strengthening of air circulation with the outside space, and thus the intensive energy metabolism and activity were found in the spaces with window and sunny weather, except for the higher lipid synthesis of indoor samples than that of outdoor ones. Furthermore, there were significant differences in fungal community composition and abundance between sunny and rainy weathers. A considerable number of species have been identified as indicator in various environmental and weather conditions of the
archives, and temperature and humidity were thought to have significant correlations with the abundance of these species. Meanwhile, Cladosporium and Alternaria were the dominant genera here, which may pose a threat to the health of archive professionals. Therefore, monitoring and controlling the growth of these fungal species is crucial for both conservation of paper records and health of archive professionals.
