Activity of peroxsidase and polyphenoloxidase of the soils in North-East part of Azerbaijan have been studied. The relation of these ferment activities to the content of humus in soils has been shown: a direct one- for polyphenoloxidase and an inverse one-for peroxidase. From the studied soils of Azerbaijan were isolated and tested more 200 fungal strains belonging to the following genera: Rhizopus, Mucor, Aspergillus, Penicillium, Geotrichum, Cephalosporium, Fusarium, Trichoderma, Verticillium, Alternaria, Cladosporium. From the 8 active strains, most strains were representatives of the genera Fusarium, Cladosporium, Penicillium. Along with the isolated strains of fungi, the activity of oxidoreductases was exhibited by museum strains of predatory fungi of the genera Arthrobotrys and Nematophagus.
