Abstract
Comparison of susceptibility of European aspen (Populus tremula L.) and oak (Quercus sp.) against molds Aspergillus niger (Tiegh) and Chaetomium globosum ((Kunze)Fr.). In the conditions of high moisture wood is exposed to molds, which not only influences on wood appearance, but also are dangerous to human life. European aspen wood (Populus tremula L.) is traditionally used for roofing and fence building. It also finds more and more uses both indoor and outdoor, where it can be exposed to molds. Comparison of susceptibility towards growth mold Aspergillus niger (Tiegh) and Chaetomium globosum ((Kunze)Fr.) between aspen wood and oak sapwood (Quercus sp.) have been made. The result of this research showed, that aspen wood is less susceptible toward growth of Aspergillus than oak sapwood. The susceptibility of aspen wood towards development of Chaetomium is comparable to oak, although slightly lower rate of mycelium growth has been observed. This result may be explained by the fact, that trembling aspen wood contains less nonstructural components than oak, therefore the environment for mold growth on aspen is less fertile. Keywords:
