METHOD TO PROTECT YEAST SACCHAROMYCES CEREVISIAE AGAINST OXIDISING STRESS CAUSED BY EXPOSURE TO HYDROGEN PEROXIDE Russian patent published in 2013 - IPC C12N1/16 C12Q1/02 C12N13/00 

FIELD: biotechnologies.

SUBSTANCE: method to protect yeast Saccharomyces cerevisiae against oxidising stress as a result of exposure to hydrogen peroxide includes growing of yeast culture under standard conditions till the end of the logarithmic or the start of the stationary phase of growth, incubation with a protective agent, exposure to hydrogen peroxide with subsequent determination of the number of survived cells. The protective agent is represented by soy inhibitors of proteases in concentration of 0.1-2.0 g/l. The time of incubation with the protective agent makes 5-6 hr, concentration of hydrogen peroxide is 700-750 mM. The invention provides for high extent of yeast cells production with no depressant action.

EFFECT: share of survived yeast cells during method realisation increases in comparison with the reference one 1,2-5,4 times.
