TLDR
Expressing a Pichia stipitis gene encoding a sugar transporter, SUT1, in a xylose-assimilating S. cerevisiae strain increased bothxylose uptake ability and ethanol productivity during xylosedehydrogenase and xylulokinase and glucose uptake ability during glucose fermentation also increased by expressing of Sut1.About:

Engineering of yeast hexose transporters to transport d-xylose without inhibition by d-glucose
TL;DR: A yeast growth-based screening system is set up for mutant d-xylose transporters that are insensitive to the presence of d-glucose, and determines that Gal2-N376F had the highest affinity for d-Xylose, along with a moderate transport velocity, and had completely lost the ability to transport hexoses.

Pathways of lignocellulosic biomass conversion to renewable fuels
TL;DR: In this paper, a broad-spectrum assessment of the above pathways is rare in literature in terms of technology used, biofuel yields, potential challenges and possible outcomes, as well as the potential solutions which do not restrict them to different biofuel production pathways.

Xylose fermentation by Saccharomyces cerevisiae
Peter Kötter,Michael Ciriacy +1 more
TL;DR: Limitations of xylose utilization in S. cerevisiae cells are very likely caused by an insufficient capacity of the non-oxidative pentose phosphate pathway, as indicated by accumulation of sedoheptulose-7-phosphate and the absence of fructose-1,6-bisph phosphate and pyruvate accumulation.

Metabolic engineering for improved fermentation of pentoses by yeasts
Thomas W. Jeffries,Yong Su Jin +1 more
TL;DR: Researchers have engineered xylose metabolism in S. cerevisiae, showing that adapted strains of Pichia stipitis have been shown to ferment hydrolysates with ethanol yields of 0.45 g g−1 sugar consumed, so commercialization seems feasible for some applications.
