Abstract

The article is focused on comparison of inhibition effect of two types of silver nanoparticles and silver ions on mold growth on surfaces of building materials. Nanoparticles of silver are product of different producers prepared by different way (e. g. chemical to mechanical). We used typical mold mixture of commonly occurring fungal species in middle Europe especially in the middle of Czech Republic including Trichoderma, Penicillium, Alternaria, Paecilomyces. They were isolated from samples taken in the air exposition. But the mold, used in experiment, were received from a Czech Collection of Microorganisms (CCM). It is not proved that type of biodeteriogens in the air correlates with isolated species on buildings facades. Tested building materials were gypsum and wooden based. Presented results show that protection against mold by silver nanoparticles and ions is not universally applicable protection for all tested materials.
