Modification of biomass production and biochemical composition of Saccharomyces cerevisiae CNMN-Y-18 and Saccharomyces cerevisiae CNMN-Y-20 yeasts under the action of extremely high frequency electromagnetic radiation

Resumo

The effect of electromagnetic radiation of an extremely high frequency on the productivity and biosynthetic activity of Saccharomyces cerevisiae CNMN-Y-18 and Saccharomyces cerevisiae CNMN-Y-20 yeast strains, depending on the duration of irradiation, has been revealed. It was established that at the irradiation with millimeter waves with a frequency of 53.33 GHz during 10 and 20 minutes the amount of biomass, carbohydrates, mannoproteins, β-glucans, proteins gets the maximum and the catalase activity is the highest. For the first time, procedures to increase the content of mannoproteins and β-glucans using the electromagnetic radiation of an extremely high frequency as stimulating factor, are proposed.
