介绍了波兰六个不同博物馆和档案馆的空气和表面微生物污染分析结果。结果表明，空气中的微生物污染水平为1.5 x 10（2）至7.0 x 10（3）cfu M-3;表面污染为1.4 x 10（2）至1.7 x 10（4）cfu 100 cm（-2）。污染博物馆和档案馆的最常见真菌是曲霉属、青霉属、枝孢属、链格孢属、毛霉属、根霉属、木霉属、拟青霉属、短梗霉属、葡萄孢属和假丝酵母属;诊断出一些潜在的致敏性和毒性菌种：烟曲霉、黄曲霉、赭曲霉、寄生曲霉、杂色曲霉、金黄色葡萄球菌。对于分析区域中出现频率最高的32种细菌和真菌菌株以及ATCC保藏的6种菌株，测定了制备纳米银的MIC和MBC。粒径为10-100 nm的纳米银浓度为90 ppm时，可以有效去除物体表面的微生物，而浓度为45 ppm时，可以去除除耐药枯草杆菌和木糖葡萄球菌外94%的所有微生物。结果表明，银纳米颗粒制剂可用作历史物品和档案文件表面的消毒剂。(C)2011爱思唯尔有限公司版权所有。
The results of microbial contamination analysis of air and surfaces in six different museums and archives in Poland are presented. It was shown that the level of microbial contamination of the air ranged from 1.5 x 10(2) to 7.0 x 10(3) cfu M-3; contamination of the surfaces was 1.4 x 10(2) to 1.7 x 10(4) cfu 100 cm(-2). The most common fungi contaminating museums and archives were Aspergillus, Penicillium, Cladosporium, Alternaria, Mucor, Rhizopus, Trichoderma, Paeciliomyces, Aureobasidium, Botrytis and Chrysonila: and from bacteria Bacillus. Some potentially allergenic and toxic species were diagnosed: Aspergillus fumigatus, Aspergillus flavus, Aspergillus ochraceus, Aspergillus parasiticus, Aspergillus versicolor, Staphylococcus aureus. For 32 strains of bacteria and fungi with the highest occurring frequency in the analyzed areas and for 6 strains of ATCC collection, MIC and MBC for the preparation of nanosilver were determined. A concentration of nanosilver with a particle size 10-100 nm at the level of 90 ppm is effective in removing the microorganisms present on the surface of objects, while a concentration of 45 ppm removed 94% of all microorganisms except for the resistant Bacillus subtilis and Staphylococcus xylosus. It was shown that a preparation of silver nanoparticles can be used as a disinfectant for the surface of historical objects and archival documents. (C) 2011 Elsevier Ltd. All rights reserved.
