Efficient conversion of xylose to ethanol is an essential factor for commercialization of lignocellulosic ethanol. To minimize production of xylitol, a major by-product in xylose metabolism and concomitantly improve ethanol production, Saccharomyces cerevisiae D452-2 was engineered to overexpress NADH-preferable xylose reductase mutant (XR(MUT)) and ...

Lignocellulosic (LC) feedstock is the most economical and renewable natural feedstock of chemicals and energy. It is primarily composed of lignin, cellulose, and hemicellulose which are woven together and render the biomass recalcitrant to degradation.

Repression of xylose utilization by glucose in xylose-fermenting yeasts
Canadian Journal of Microbiology, 1988The xylose-fermenting yeasts Pichia stipitis, Candida steatolytica, and Candida shehatae were subjected to fermentations in synthetic media containing mixtures of glucose and xylose. In all cases, repression of xylose uptake by glucose was observed, although the extent of repression was different with each yeast.

Xylose Absorption and Duodenal Diverticula
JAMA: The Journal of the American Medical Association, 1967To the Editor:— Numerous investigators 1-4 have reported that the measurement of the urinary excretion of xylose after the oral administration of the sugar is a reliable means of testing the absorption of carbohydrates. Xylose is not metabolized by the body but is excreted unchanged in the urine.
