Changes in the activity of micromycete endocellular oxidoreductases under the influence of low-frequency pulsed magnetic field and low-intensity laser radiation

Abstract

This study aims to investigate the effects of low-frequency pulsed magnetic field (1.5 Hz) and low-intensity laser radiation (0.3 and 0.7 W) on the activity of micromycete endocellular oxidoreductases that catalyze biodegradation of industrial materials such as Penicillium cyclopium, Aspergillus niger, and Alternaria alternata. The investigated physical factors had dose-dependent effects on the activity of fungal endocellular oxidoreductases (catalase and peroxidase): increases and decreases in the activities of enzymes have been observed. An increase in the activity of enzymes can contribute to the manifestation of the adaptive properties of fungi against the action of such physical factors as low-intensity laser radiation and magnetic field. A decrease in the activity of endocatalase and endoperoxidase under the influence of these factors may suppress the vital activity of microorganisms.
