Abstract

Biological degradation of documentary heritage is a serious issue faced by libraries, museums and archives as it can lead to paper becoming brittle, fragile and discoloured, resulting in a loss of information. This study investigates the impact of didecyldimethylammonium bromide (DDAB) on the properties of pure or inked paper and the growth of different types of fungi. Three fungi species known for their ability to cause paper biodeterioration in libraries and museums, Aspergillus clavatus Desm, Penicillium paneum Frisvald and Ulocladium chartarum Preuss, were selected for the DDAB salt antifungal activity test. The study measured the pH and degree of polymerization (DP), monitored colour changes and conducted scanning electron microscopy analyses (SEM) to confirm that DDAB can be used as a biocide for fungi on pure or inked paper. The study also investigated the antifungal effect of DDAB on paper treated with different types of ink, including black (iron-gall ink) and brown (copper ink). Didecyldimethylammonium bromide (DDAB) can be used as a biocide for cleaning and preserving paper documents, with active concentrations of 0.7 and 1%.

季铵盐对水墨纸保鲜的抑菌作用研究

文献遗产的生物降解是图书馆、博物馆和档案馆面临的一个严重问题，因为它可能导致纸张变脆、易碎和变色，从而导致信息丢失。本研究研究了二癸基二甲基溴化铵（DDAB）对纯纸或油墨纸性能以及不同类型真菌生长的影响。在DDAB盐抗真菌活性测试中，选择了三种因其在图书馆和博物馆中引起纸张生物降解的能力而闻名的真菌，棒曲霉（Aspergillus clavatus Desm）、潘氏青霉（Penicillium paneum Frisvald）和黄曲霉（Ulocladium chartarum Preuss）。该研究测量了pH值和聚合度（DP），监测了颜色变化，并进行了扫描电子显微镜分析（SEM），以确认DDAB可以用作纯纸或墨水纸上真菌的杀生物剂。该研究还研究了DDAB对用不同类型墨水处理的纸张的抗真菌作用，包括黑色（铁胆墨水）和棕色（铜墨水）。二癸基二甲基溴化铵（DDAB）可用作清洁和保存纸质文件的杀生物剂，其活性浓度分别为0.7%和1%。
