“…Under favorable conditions, microbes capable of biodeterioration can settle onto historical objects and into environments in which they are collected and stored (15). If they grow actively, they can cause changes on the surface of documents, such as discolorations or stains, and can weaken the structure of the material and increase its brittleness until complete destruction occurs (3,(16)(17)(18)(19). In discussions of the microbial hazards of cultural heritage objects, filamentous fungi and actinobacteria are the most important microbes, since, in comparison with bacteria, they are capable of growing actively in environments with lower temperature and relative humidity.…”

The literature of environmental microbiology broadly discusses issues associated with microbial hazards in archives, but these publications are mainly devoted to paper documents. There are few articles on historical parchment documents, which used to be very important for the development of literature and the art of writing. These studies present a broad spectrum of methods for the assessment of biodeterioration hazards of the parchment document in question. They are based on both conventional microbiological methods and advanced techniques of molecular biology. Here, a qualitative analysis was conducted, based on genetic identification of bacteria and fungi present on the document as well as denaturing gradient gel electrophoresis profiling and examining the destructive potential of isolated microbes. Moreover, the study involved a quantitative and qualitative microbiological assessment of the indoor air in the room where the parchment was kept. The microbes with the highest destructive potential that were isolated from the investigated item were Bacillus cereus and Acinetobacter lwoffii bacteria and Penicillium chrysogenum, Chaetomium globosum, and Trichoderma longibrachiatum fungi. The presence of the B. cereus strain was particularly interesting since, under appropriate conditions, it leads to complete parchment degradation within several days.

“…Table exhibits the MIC and the MBC of the chitosan‐CMC silver nanocomposite. The antibacterial activity is affected by release of silver nanoparticles, as well as the size of the nanoparticles and the type of the microorganisms . The MBC/MIC ratio is a parameter that indicates the bactericidal capacity of the silver nanocomposite.…”

Chitosan‐carboxymethyl cellulose (CMC) full polysaccharide membrane was prepared by cross‐linking of chitosan with CMC dialdehyde and subsequent reductive amination. CMC dialdehyde molecule was prepared by periodate oxidation of CMC and then applied as a cross‐linking agent to form a new membrane network. The properties of oxidized CMC were investigated by various methods such as Fourier transform infrared (FT‐IR) spectroscopy, 1H NMR spectroscopy, and viscosity test. Then, novel chitosan‐CMC silver nanocomposite was prepared using chitosan‐CMC as a carrier. The structure of the chitosan‐CMC membrane and the silver nanocomposite were confirmed by FT‐IR spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), and thermogravimetric analysis (TGA). TEM images indicate that the chitosan‐CMC nanocomposite comprises silver nanoparticles with diameters in the range of about 5–20 nm. The antibacterial studies of the nanocomposite were also evaluated. The chitosan‐CMC silver nanocomposite demonstrates good antibacterial activity against Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli. Copyright © 2016 John Wiley & Sons, Ltd.

“…A sensitivity to nanosilver has been shown, with different levels of sensitivity among species. Gutarowska et al [49] reported that Aspergillus, Penicillium and Rhizopus are silver nanoparticle-resistant microfungi, while Alternaria, Cladosporium and Mucor are sensitive. Therefore, more studies are needed on the optimization of using silver nanoparticles and developing humanenvironmental friendly solutions.…”

Ö ZB u çalışmada, İstanbul Üniversitesi'nin farklı bölümlerindeki hava kökenli fırsatçı mikrofungal patojenlerin derişiminin ve kompozisyonunun belirlenmesi amaçlanmıştır. Dikloran gliserol 18 agar ve malt özüt agar izolasyon için kullanılmış ve sırasıyla tüm örnekleme süresince toplam 1830 ve 1290 mikrofungus kolonisi toplanmıştır. Avrupa Birliği Komisyon raporuna göre örnekleme alanlarındaki kirlilik seviyeleri sınıflandırılmıştır. Diğer örnekleme alanlarında orta düzeyde kirlilik seviyesi saptanırken, Arşiv 1'de yüksek seviyede kirlilik saptanmıştır. En yaygın hava kökenli mikrofunguslar Aspergillus flavus, Aspergillus amstelodami, Aspergillus niger ve Aspergillus fumigatus olarak tanımlanmıştır. Anahtar KelimelerHava kalitesi, kütüphane, mikrofungus, volümetrik hava örneklemesi. A B S T R A C TT his study aimed to determine the concentration and composition of opportunistic airborne microfungal pathogens in different parts of the library of İstanbul University, Turkey. Dichloran glycerol 18 agar and malt extract agar were used for isolation and a total of 1830 and 1290 microfungal colonies were collected during the whole study period, respectively. Contamination levels in sampling areas were classified according to the Commission of European Communities report's classifications and a high contamination level was determined in Archive 1, while an intermediate contamination level was determined in other sampling areas. The most common airborne microfungi were identified as Aspergillus flavus, Aspergillus amstelodami, Aspergillus niger and Aspergillus fumigatus.
