Title: Nian-Qing Shi: Innovator in Yeast Fermentation Technology
Introduction
Nian-Qing Shi is a notable inventor based in Forsyth, IL (US). She has made significant contributions to the field of biotechnology, particularly in yeast fermentation processes. With a total of 2 patents, her work focuses on enhancing the efficiency of ethanol production from xylose.
Latest Patents
One of her latest patents is titled "Sham-sensitive terminal oxidase gene from xylose-fermenting yeast." This patent discloses a SHAM-sensitive terminal oxidase (STO) gene from xylose-fermenting yeast. It also describes a mutant strain in which the STO gene natively present in the wild-type yeast was disrupted. The mutants with reduced expression of PsSTO were found to exhibit enhanced fermentation of xylose to ethanol. Another significant patent is "Disruption of the cytochrome C gene in xylose-fermenting yeast." This patent reveals a xylose-fermenting mutant yeast strain that shows reduced expression of cytochrome c and enhanced fermentation of xylose compared to strains where cytochrome c is fully functional. Additionally, it outlines a method for producing ethanol from xylose by culturing this mutant yeast strain in the presence of xylose-containing material.
