The Effect of a Magnetic Field and Low-Intensity Laser Irradiation on the Destructive Activity of Filamentous Fungi During their Growth on a Number of Industrial Products

An assessment of the impact of low-intensity laser irradiation (LILI) and magnetic field (MF) on the biodegradation of a number of industrial products: wood fiberboard (WFB) and polyester caused by filamentous fungi is presented. It has been established that the magnetic field is capable of causing intensive destruction of wood fiberboard and polyester by fungi Alternaria alternata, Aspergillus niger, then the destructive process of WFB in the case of Penicillium cyclopium remained at the control level, and in the case of polyester it slowed down. The action of LILI, on the contrary, increased the destructive activity of Penicillium cyclopium in variants with WFB, and for polyester in the fungi Alternaria alternata, Aspergillus niger. Differences in the change in the resistance of products to fungi under the action of LILI and MF can be associated with both the physiological and biochemical characteristics of fungi and the aging process of polymers under the influence of the studied physical factors.
