Abstract

In this paper are presented results of the study of influence of the duration of irradiation by millimeter waves with extremely high frequency (53,33 GHz-λ=5,6 mm) on the development of population and viability of S. cerevisiae CNMN-Y-20 yeast strain. It was established that the irradiation of yeast strain by millimeter waves with extremely high frequency during the 5, 10, 15, 20, 25 minutes has conducted to the significant increasing of amount of generations (with 2,5-3,3 generation) and of the viability of the strain in comparison with control during the first 6 hours of cultivation. Maximum of stimulation of viability (with 56,2 %) was revealed after 24 hours of cultivation in samples irradiated during 20 minutes. Keywords: Saccharomyces cerevisiae, proliferation, viability, millimeter waves with extremely high frequency.
