În studiu sunt expuse rezultatele influenţei duratei de iradiere cu unde milimetrice cu frecvenţă extra înaltă (53,33 GHz-λ=5,6 mm) asupra dezvoltării generaţiilor populaţionale şi viabilităţii tulpinii de drojdii S. cerevisiae CNMN-Y-20. S-a stabilit că iradierea tulpinii cu unde milimetrice cu frecvenţa enunţată timp de 5, 10, 15, 20, 25 minute duce, în primele 6 ore de cultivare, la creşterea semnificativă a numărului de generaţii (cu 2,5 - 3,3 generaţii) şi a viabilităţii tulpinii comparativ cu martorul neiradiat. Efectul maximal de stimulare a viabilităţii (cu 56,2%) s-a observat după 24 ore de cultivare la probele iradiate timp de 20 de minute.

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.
