Abstract

The species diversity and the structure of the opportunistic fungi complexes in the forest Albic Podzols under the impact of the Aluminum and Copper-Nickel Plants emissions, as well as in the Hortic Anthrosol contaminated by the oil products (diesel fuel, gas condensate, mazut) in the north-west region of Russia (the Kola Peninsula) have been investigated. The share of the opportunistic fungi increase up to 15% in the zones of the Aluminum and Copper-Nickel Plants emissions comparable to the background soil, and up to 20-25% in the soils contaminated by the oil products has been revealed. The majority of the fungi species belong to the following genera: Penicillium, Aspergillus, Mucor, Lecanicillium, Phoma and Cladosporium. The structure of the fungal complexes has changed in the polluted soil, that is, the species abundance and the frequency of the opportunistic fungi occurrence have increased. The strains of the fungi isolated from the contaminated soil reveal the potential pathogenicity in a greater degree, than the strains isolated from the clean soil. 55% of the total amount of fungi strains isolated from the soils contaminated by the Aluminum Plant emissions had the potential pathogenicity. The most dangerous for a human’s health were Amorphotheca resinae, Aspergillus fumigatus, A. niger, Paecilomyces variotii, Penicillium commune, P. purpurеogenum, Trichoderma viride isolated from the soils contaminated by the Aluminum Plant emissions; and P. aurantiogriseum, P. glabrum, P. commune, P. simplicissimum, Rhizopus nigricans isolated from the soils contaminated by the oil products. Those species revealed protease, phospholipase activity, as well as the growth ability at the temperature 37°C
