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. Enhanced
## Abstract The influence of glucose on xylose reductase (XR) and xylitol dehydrogenase (XDH) enzyme activity was evaluated from sugarcane bagasse hydrolysate fermentations with different glucose:xylose ratios (1:25, 1:12, 1:5 and 1:2.5) by employing an inoculum of __Candida guilliermondii__ grown
## Abstract BACKGROUND: Xylitol is a sugar alcohol (polyalcohol) with many interesting properties for pharmaceutical and food products. It is currently produced by a chemical process, which has some disadvantages such as high energy requirement. Therefore microbiological production of xylitol has b
To enhance metabolite transfer in the two initial sequential steps of xylose metabolism in yeast, two structural genes of Pichia stipitis, XYL } and XYL " encoding xylose reductase (XR) and xylitol dehydrogenase (XDH), respectively, were fused in frame. Four chimeric genes were constructed, encoding
