Fungi in air and on wooden constructions of old historical building

Abstract

In this research the microfungi biodestruction of wooden constructions in the historical building was analyzed. Since the main artifacts in the Museum of Folk Architecture and Life of Ukraine "Pyrogovo" are built of wood, they are extremely vulnerable to the action of biological agents, especially microfungi. The house of village Samary from Volyn region, which is the most ancient artifact in the museum, was examined to identify the fungi spectrum on the wood and in the air. 20 samples of building constructions and 8 air samples have been collected inside and outside the studied house. In total, 11 species and genus (35 specimens) of microfungi were identified from 20 samples of building constructions of the studied house. 25 fungi specimens belonging to 6 species (Aspergillus niger, Alternaria tenuissima, Chaetomium globosum, Mycelia sterilia, Stachybotrys chartarum, Trichoderma viride) and 4 fungi which was possible identified only to genus Acremonium, Fusarium, Mocladium and Penicillium were found on wood walls. The most abundant species of the Samary house on the construction substratum were Aspergillus niger and Alternaria tenuissima, in the air - Aspergillus flavus, A. repens, A. niger and Alternaria tenuissima.
