The influence of various parameters of the electromagnetic radiation of millimeter range: wavelength (λ-4, 9, 5.6, 7.1 mm), the irradiation regimes (periodic, continuous), duration of exposure (10–60 minutes) on the biosynthesis of extracellular hydrolases and vital cycles of fungi Aspergillus niger 33 and Aspergillus niger 33–19 CNMN FD 02A – producers of amylases and Penicillium viride CNMN FD 04P – producer of pectinases was studied. It was established that the efficiency impact depends on the physical parameters of the radiation and the properties, the functional state of strains. Particularly for each strain - producer, the optimal irradiation conditions, which providing an opportunity to increase the biosynthesis and secretion of exocellular hydrolases up to 44,4–49,4% compared with the control variants, were established. Additionally, in the case of micromycetes Aspergillus niger 33–19 CNMN FD 02A the acceleration of growth cycle by 48 hours was observed.
