Effect of enhanced xylose reductase activity on xylose consumption and product distribution in xylose-fermenting recombinant [PDF]
FEMS Yeast Research, 2003 Recombinant Saccharomyces cerevisiae TMB3001, harboring the Pichia stipitis genes XYL1 and XYL2 (xylose reductase and xylitol dehydrogenase, respectively) and the endogenous XKS1(xylulokinase), can convert xylose to ethanol. About 30% of the consumed xylose, however, is excreted as xylitol.

Rational and evolutionary engineering approaches uncover a small set of genetic changes efficient for rapid xylose fermentation in Saccharomyces cerevisiae. [PDF]
PLoS ONE, 2013 Economic bioconversion of plant cell wall hydrolysates into fuels and chemicals has been hampered mainly due to the inability of microorganisms to efficiently co-ferment pentose and hexose sugars, especially glucose and xylose, which are the most ...

The Weimberg pathway: an alternative for Myceliophthora thermophila to utilize d-xylose
Biotechnology for Biofuels and Bioproducts, 2023 Background With d-xylose being the second most abundant sugar in nature, its conversion into products could significantly improve biomass-based process economy. There are two well-studied phosphorylative pathways for d-xylose metabolism. One is isomerase
