Lignin als biologische Barriere gegen Schimmelpilze in Innenräumen
[Lignin as a biological barrier against mould fungi inside buildings]
Gesunde Pflanzen 65 (1), 15-20
Abstract: Many different fungi grow indoors as mold in the presence of moisture. Some of these fungi can cause allergic or toxic reactions, while a few may cause infections in susceptible individuals. A comprehensive treatment of this complex topic is still lacking. As part of investigations on alternative management strategies of these fungi, it is tested if the growth of nine fungi (Alternaria alternata, Botrytis cinerea, Cladosporium herbarum, Fusarium culmorum, F. solani, F. verticillioides, Mucor sp., Penicillium sp. and Trichoderma sp.) which are all common inside buildings could be inhibited by mixing lignin into wall plaster. On maltextract agar, lignin concentrations above 10 % inhibited mould growth except for Penicillium sp. Further studies with a lignin-plaster-agar, which contained only plaster as nutrient and had a high pH at 8, showed no inhibition on the tested fungi (Alternaria alternata, Fusarium verticillioides, Mucor sp., Trichoderma sp. and Penicillium sp.) at concentrations up to 5 %. Higher lignin concentrations lead to insufficient quality of building materials, e. g. cracking. Furthermore, the color of the building materials turned from greyish-white in an exotherm reaction into brown, which was no longer suitable for construction purposed.
