The level of glucose-6-phosphate dehydrogenase activity strongly influences xyl...
Jeppsson, Marie; Johansson, Björn; Jensen, Peter Ruhdal; Hahn-Hägerdal, Bärbel; Gorwa-Grauslund, Marie F.Disruption of the ZWF1 gene encoding glucose-6-phosphate dehydrogenase (G6PDH) has been shown to reduce the xylitol yield and the xylose consumption in the xylose-utilizing recombinant Saccharomyces cerevisiae strain TMB3255. In the present investigation we have studied the influence of different production levels of G6PDH on xylose fermentation. We used a synthetic promoter library and the copper...
Effect of enhanced xylose reductase activity on xylose consumption and product ...
Jeppsson, Marie; Träff, Karin; Johansson, Björn; Hahn-Hägerdal, Bärbel; Gorwa-Grauslund, Marie F.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 ethanol yield has previously been achieved by disrupting the ZWF1 gene, encoding glucose-6- phosph...
