Fungal growth on cellulose-based materials in libraries can have detrimental effects on books and documents. This biodeterioration affects their physical, chemical, and esthetical characteristics. Thus, this work aimed to assess fungal aerosols' concentrations and biodeterioration risk in two public libraries with artificial ventilation: the Banco de la República and CAJAMAG libraries. Air sampling was performed using a two-stage viable Andersen cascade impactor with Sabouraud dextrose agar at 4% on Petri dishes. Also, the temperature and relative humidity were measured with a digital thermo-hygrometer HOBO U12 Data Logger. The concentrations were low, with values of around 35 CFU/m. , , and were the predominant genera in the two libraries, with being the most abundant species. The thermo-hygrometric conditions inside the libraries were stable, with a mean temperature of 25.2 °C and a mean relative humidity of 52.1%. The calculated potential risk associated with fungal aerosols was seen to be medium in both libraries, where genera reported the highest cellulosic activity and hence had a higher risk of biodeterioration.
图书馆中基于纤维素的材料上的真菌生长会对书籍和文件产生有害影响。这种生物劣化会影响它们的物理、化学和美学特性。因此，这项工作旨在评估两家采用人工通风的公共图书馆——共和国银行图书馆和CAJAMAG图书馆中真菌气溶胶的浓度和生物劣化风险。使用带有4%沙氏葡萄糖琼脂的两级活态安德森级联撞击器在培养皿上进行空气采样。此外，使用数字温湿度计HOBO U12数据记录器测量温度和相对湿度。浓度较低，约为35 CFU/m³。在这两家图书馆中，曲霉属、青霉属和枝孢属是主要的属，其中曲霉属是最丰富的物种。图书馆内的温湿度条件稳定，平均温度为25.2℃，平均相对湿度为52.1%。在这两家图书馆中，与真菌气溶胶相关的计算潜在风险被认为是中等的，其中曲霉属报告的纤维素活性最高，因此生物劣化风险更高。
