The influence of medicine plant extracts on viability of yeast cells of Saccharomyces cerevisiae and Saccharomyces carlsbergensis under the action of ionizing radiation

Abstract

Abstract As noted in the literature review, the effect of H2O2 on a living cell as an oxidative stress agent is in many ways similar to the effect of X-ray radiation. In living cells, both H2O2 and X-ray irradiation cause oxidative stress and induce the same system of antioxidant anti-stress response. In addition, small doses of radiation can carry certain signaling functions in relation to the activity of microorganisms. In this regard, at this stage of research, it was interesting to find out whether exposure at a dose of 400 Gy and 800 Gy of X-ray radiation could be favourable for the growth of microorganisms with the introduction of extracts of medicinal plants and under which conditions.
