[Contamination of solid-cast rubber tires by microscopic fungi].

The main peculiarities of fungal resistance of two types of unit cast rubber tires of domestic manufacture have been investigated. Rubber tires which contained synthetic plasticizer were non-resistant to fungal contamination in contrast to ones with natural plasticizer. Using the method of confocal laser-scanning microscopy, it was shown that inner layers of two types of rubber tires were contaminated with fungal mycelium.

[Effect of heavy metal ions on the soil mycobiota in Kryvyĭ Rih region].

Ecological-taxonomic analysis of mycobiota from heavy metal polluted soils in Kryvyi Rig town and its residential suburbs are presented in this study The mycobiota consists of45 filamentous species (127 strains) belonging to 28 genera from 3 divisions. Among them Myrothecium leucotrichum was described as a new species for Ukrainian mycobiota while Absidia cylindrospora and Gongronella butleri as rare species. Paecilomyces lilacinus and P.

[Copper ions sorption by soil micromycetes].

This study gives a comparison of copper ions sorption ability of micromycetes (72 strains) isolated from both modern and archaeological soils polluted with heavy metals. Copper sorption ability was inter- and intra-specific with Cladosporium cladosporioides 77, C. cladosporioides 716 and Stachybotrys chartarum 357, S.

[Colonization and destruction of concrete by mitosporic fungi in model experiment].

When investigating the action of microscopic fungi of genera Aspergillus, Alternaria, Cladosporium and Paecilomyces on concrete specimens in the model system, it was shown that the fungi can colonize successfully the concrete surface during 1 year and cause its destructive changes. However the fungi did not colonize those sections of concrete surface which were filled with granite. The fungi leached chemical elements of concrete into nutrition medium, accumulated them in their biomass and caused their transformation into newly-formed crystals of calcium oxalates on the surface of concrete.
