1.1.1.430 synthesis fermentation of mixed glucose-xylose substrates in Saccharomyces cerevisiae strains BP10001 and BP000, expressing Candida tenuis xylose reductase in mutated NADH-preferring form and NADPH-preferring wild-type form, respectively. Glucose and xylose, each at 10 g/l, are converted sequentially. The distribution of fermentation products from glucose is identical for both strains whereas when using xylose, BP10001 shows enhanced ethanol yield and decreased yields of xylitol and glycerol as compared to BP000. Increase in xylose concentration from 10 to 50 g/l results in acceleration of substrate uptake by BP10001 and reduction of the xylitol yield. In mixed substrate batches, xylose is taken up at low glucose concentrations and up to 5fold enhanced xylose uptake rate is found towards glucose depletion Yamadazyma tenuis
