✦ Synopsis
charomyces cerevisiae strains expressing the XYL1 gene, 1997.
coding for xylose reductase (XR), at different levels, the Keywords: xylitol production; recombinant Saccharo-'low XR strain' at 0.51 U/mg and the 'high XR strain' at myces cerevisiae; protein burden; plasmid stability 10.8 U/mg, was compared in batch and fed-batch culture. Xylose was not consumed in the presence of high glucose concentrations, because both sugars are transported by the glucose transport system, which has a higher affinity
