MICROMYCETES STABILITY TO THE HEAVY METALS COMPOUNDS JOINT ACTION

Abstract

It has been studied the micromycetes stability to the joint action of nitric acid compounds of cadmium, zinc, copper, nickel and lead. Most sensible to minimum maintenance (0.75 MPC) of heavy metals compounds in the Chapek medium were Absidia butleri Lendn, Mortierella vaneсаe DixonStewart, Cunninghamella echinulata Thaxter, Curvularia tuberculata Jain and Fusariu solani (C. Mart.) Appel et Wollenw, while at Trichodermа longibrachiatum Rifai, Alternaria alternatа (Fr.) Keissl, Penicillium sp4 and Mucor globоsus Ficher moderate growth was observed even at a maximal concentration (50 MPC). The most inhibition of biomass synthesis (in 7.3 times) at the concentration of heavy metal ions in medium 3 MPC is marked at Penicillium sp1.
