Xylose metabolism by Pichia stipitis: the effect of ethanol

open access: yesApplied Microbiology and Biotechnology, 1991
Pichia stipitis Y7124 was grown anaerobically on d-xylose in the presence of an initial ethanol concentration (E0) varying from 0 to 40 g/l. When E0 increased, the yield of xylitol increased linearly, reaching a value of 0.20 mol xylitol/mol xylose at E0=40 g/l.

Oxidative d-xylose metabolism of Gluconobacter oxydans

open access: yesApplied Microbiology and Biotechnology, 1988
Gluconobacter oxydans subsp. suboxydans ATCC 621 oxidizes d-xylose to xylonic acid very efficiently, although it cannot grow on xylose as sole carbon source. The oxidation of xylose was found to be catalyzed by a membrane-bound xylose dehydrogenase. The xylono-γ-lactone formed in the oxidation reaction is subsequently hydrolyzed to xylonic acid by a γ ...

Metabolism of d-xylose in Schizosaccharomyces pombe cloned with a xylose isomerase gene

Applied Microbiology and Biotechnology, 1989
The Escherichia coli xylose isomerase gene was transformed into Schizosaccharomyces pombe for direct d-xylose utilization. In order to understand d-xylose metabolism and determine the limiting factors on d-xylose utilization by the transformed yeast, d-xylose transport, xylose isomerization, and xylulose phosphorylation were investigated.

Impact of overexpressing NADH kinase on glucose and xylose metabolism in recombinant xylose-utilizing Saccharomyces cerevisiae

open access: yesApplied Microbiology and Biotechnology, 2009
During growth of Saccharomyces cerevisiae on glucose, the redox cofactors NADH and NADPH are predominantly involved in catabolism and biosynthesis, respectively. A deviation from the optimal level of these cofactors often results in major changes in the substrate uptake and biomass formation.

Strain engineering of Saccharomyces cerevisiae for enhanced xylose metabolism

Biotechnology Advances, 2013
Efficient and rapid fermentation of all sugars present in cellulosic hydrolysates is essential for economic conversion of renewable biomass into fuels and chemicals. Xylose is one of the most abundant sugars in cellulosic biomass but it cannot be utilized by wild type Saccharomyces cerevisiae, which has been used for industrial ethanol production ...
