The Occurrence of Mold in Construction Materials before Inbuilt into New Building and Protection against this Type of Biodegradation

Mold together with other microorganisms are belonging to the group of biodeteriogens which is common occurred on both the inner and outer surfaces of building structures. Mentioned study is comparing the generic composition of mold on the surface of board materials (wood and plaster based) with the generic composition of mold trapped air in Central Bohemia. In the air they were identified following species of mold: Cladosporium, Aspergillus, Penicillium, Aureobasidium, Epiccocum, Alternaria, Mucor. The almost identical species of mold was found on board materials. It also investigated the minimal inhibitory concentrations of silver nanoparticles against selected mold (Cladosporium, Aspergillus, Penicillium, Aureobasidium, Epiccocum, Alternaria). The results show that the minimum inhibitory concentration for most of mold is 1.5 g / m2 except Apergillus species, where the minimum inhibitory concentrations have a double value.
