چکیده
Background: Paper substrates are highly susceptible to fungal degradation, as fungi produce enzymes that decompose paper materials. This study investigates and compares the antifungal efficacy of silver nanoparticles (AgNPs) synthesized through various physical and biological methods. The fungal strains tested, Penicillium sp. and Aspergillus sp., were isolated from paper samples in a previous study, chosen for their more prevalence in contaminated paper.Methods: Five types of AgNPs, synthesized using both biological and physical methods, were evaluated. The biological methods involved the use of extracts from Juglans regia green husk, Malva sylvestris leaves, and cyanobacterial cells. The minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) of the AgNPs were determined using standard protocols.Results: The MIC values of the AgNPs synthesized from different sources exhibited varying degrees of antifungal activity against the tested fungi. The AgNPs’ effectiveness ranked as follows: (۱) AgNPs produced by Nostoc pruniforme, (۲) AgNPs produced by M. sylvestris, (۳) AgNPs produced by Nostoc IBRC-M۵۰۶۴, (۴) AgNPs produced by J. regia, and (۵) physically synthesized AgNPs.Conclusion: These findings highlight the potential of biologically synthesized AgNPs as environmentally friendly biocidal agents for preventing and controlling paper biodegradation.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
