Title: Olena Ishchuk: Innovator in Yeast Ethanol Tolerance
Introduction
Olena Ishchuk is a prominent inventor based in Lviv, Ukraine. She has made significant contributions to the field of biotechnology, particularly in the study of yeast and its tolerance to ethanol and high temperatures. With a total of 5 patents, her work has garnered attention in both academic and industrial circles.
Latest Patents
One of her latest patents focuses on genes conferring tolerance to ethanol and high temperature in yeasts. The methods described in this patent detail the identification of genes that confer ethanol tolerance, as well as the use of mutant strains to identify such genes. A gene designated as HpETT1 was isolated from yeast, and its expression in an ethanol-sensitive mutant strain, known as 7E, complemented the ethanol sensitivity of the mutant. When multiple copies of HpETT1 were integrated into the genome and overexpressed, the transformed strain exhibited approximately 10-fold greater resistance to ethanol and also showed resistance to the protein misfolding agent AZC. Furthermore, the expression of HpETT1 increased ethanol tolerance in the yeast. Notably, HpEtt1 has a 39% sequence identity to a previously identified protein denoted as MPE1, although the MPE1 gene does not confer ethanol resistance to the 7E mutant. Another gene from the yeast, designated PsETT1, encodes an orthologue protein with 37% identity to HpETT1 and also confers ethanol resistance to the 7E mutant.
