- Аннотация: Original data on the growth parameters of the fungi Penicillium chrysogenum Thom, Aspergillus repens (Corda) Sacc., and Trichoderma viride Pers. isolated from living spaces in Moscow are presented. Spore germination, fungal growth, and the radial growth rate of the colonies were investigated upon cultiva tion on agarized nutrient media with different water activity (aw) values. Spore germination and fungal growth were studied in house dust under laboratory conditions at different relative air humidity (RH). It was shown that, at decreased aw and RH, the spore germination time increased, as did the period from germination to mycelium and conidia formation, while the radial growth rate of colonies decreased. House dust was found to be a suitable growth substrate for A. repens and P. chrysogenum, supporting their complete life cycle. It was suggested that house dust is unsuitable as a substrate for the growth of T. viride. The aw and RH ranges for development of these micromycetes were determined. On this basis, the A. repens, P. chrysogenum, and T. vir ide strains isolated from living spaces were identified as xerophilic, xerotolerant, and hygrophilic ones, respectively.
