The effects of a low-frequency pulsed magnetic field (1.5 Hz) and low-intensity laser radiation (0.3 and 0.7 W) on the activity of intracellular oxidoreductases of micromycetes, Penicillium cyclopium , Aspergillus niger , and Alternaria alternata , which are active agents of biodegradation of industrial materials, were studied. The studied physical factors had dose-dependent effects on the activity of fungal intracellular oxidoreductases (catalase and peroxidase); both an increase and a decrease in enzyme activity were observed. An increase in the activity of enzymes can contribute to the manifestation of the adaptive properties of fungi to the action of such physical factors as low-intensity laser radiation and magnetic field. A decrease in the activity of intracellular catalase and peroxidase under the action of these factors may inhibit the vital activity of microorganisms.
