ABSTRACT
The article presents the results of monitoring the soil mycobiota of sulfur quarries in LvivRegion. The dynamics of soil micromycete complexes as a result of their adaptation to the conditions of technozems, embryozems and zonal soils of sulfur quarries was studied. The increase in the number of colony-forming units (CFU) in the studied soils of the Yavoriv and Podorozhnie sulfur quarries over the years is specified, which indicates the active processes of decomposition of plant remains, the formation of stable processes of decomposition of cellulose and other complex compounds in the detrital block of the ecosystem. The change in the frequency of banding of selected species of micromycetes over the years was studied, depending on the content of SO4-2 in the soil solution. The functional structure of soil micromycete communities after sulfur extraction was established. A decrease in the frequency of occurrence of pathogens and toxin-producing agents and an increase in the frequency of occurrence of species that actively participate in the transformation of organic remains, and also act as plant endophytes and participants in mycorrhizal symbiosis were recorded. The species composition of micromycetes that grew in the presence of SO4-2 content in the soil solution, which exceeded the background level from 3.6% to 50%, was determined, the species-bioindicators of soil pollution with sulfur compounds were defined - Fusarium oxysporum, Paecilomyces lilacinum, P. waksmanii, P. nigricans, P. funiculosum, Trichoderma viride, Cladosporium cladosporioides, C. herbarum, Aureobasidium pullulans, Humicola grisea, Ulocladium consortiale, Alternaria alternate, Mortierella ramanniana var. angulispora. During 10 years of research a decrease in the content of SO4-2 in soils was noted, which is associated with an increase in the biodiversity of soil micromycetes and an enrichment of the phytocenotic cover.
