The sensitivity of 33 micromycete species to nitric compounds of copper, lead, zinc, nickel and cadmium has been determined. Absidia butleri Lendn, Mortierella vanesae Dixon-Stewart, Cunninghamella echinulata Thaxte, Curvularia tuberculata Jain, Cladosporium cladosporiodes (Fresen) G. A. de Vries and Fusarium solani (C. Mart.) Appel et Wollenw are sensitive to minimal content of the heavy metals (0.75 of maximum permissible concentration (MPC)) in the growth medium. At the same time Trixoderma longibrachiatiim Rifai, Alternaria alternatа (Fr.) Keissl and Penicillium sp. 4 demonstrated moderate growth under maximal concentration (50 MPC). It is determined that minimal content of the heavy metals in the initial stage of influence (up to 48 h) promotes growth of only Fusarium oxysporum E. F. Sm. et Swingle, while retards growth of the other species.
