The highest level of ethanol production was demonstrated for the strain AS400-510-42, which was obtained on the background of the industrial ethanol producer AS400 by positive selection on glyoxylic acid and glucosamine and produced 3-3.5% more of ethanol compared to the initial strain. Additionally, S. cerevisiae strains PE-2 and AS400-510-42 were adapted to growth in a medium with a high concentration of glucose and ethanol (up to 24% and 8%, respectively). The main results of the research were presented at the International Scientific Conference (theses Physiological characteristics of yeast Saccharomyces cerevisiae resistant to stress factors / O. Ternavska, M. Semkiv, H. Yavorska // XIV International scientific conference of students and postgraduates "Youth and the progress of biology", 10 April 22, 2018, Lviv, Ukraine, Collection of Theses, 2018, p. 222.), and a patent application was filed for the patent of Ukraine for a utility model (A method for obtaining strains of yeast of Saccharomyces cerevisiae capable of ethanol superproduction / MV Semkiv, K V. Dmytruk, AA Sibirny, the applicant and owner of the Institute of Cell Biology of the National Academy of Sciences of Ukraine). Also, the results of the study are planned for implementation at the SC Uhersky Alcohol Plant (village Uhersko, Ukraine).
