Journal ArticleDOI

Identification of common traits in improved xylose‐growing Saccharomyces cerevisiae for inverse metabolic engineering

Oskar Bengtsson, +6 more
- 01 Nov 2008 - 
TL;DR: Four recombinant Saccharomyces cerevisiae strains with enhanced xylose growth were compared with two control strains through genome‐wide transcription analysis in order to identify novel targets for inverse metabolic engineering.
Journal ArticleDOI

Dynamic metabolomics differentiates between carbon and energy starvation in recombinant Saccharomyces cerevisiae fermenting xylose

Basti Bergdahl, +4 more
- 15 May 2012 - 
TL;DR: The low uptake of xylose by the XI-strain led to several distinguished responses: depletion of key metabolites in glycolysis and NADPH, a reduced GTP/GDP ratio and accumulation of PEP and aromatic amino acids are strong indicators of carbon starvation.
Journal ArticleDOI

Xylose isomerase activity influences xylose fermentation with recombinant Saccharomyces cerevisiae strains expressing mutated xylA from Thermus thermophilus.

A Lönn, +4 more
- 08 Apr 2003 - 
TL;DR: Three xylose isomerase enzymes (XI) were produced at two different levels in Saccharomyces cerevisiae; xylA genes were chromosomally integrated and expressed from multicopy plasmids, respectively.
Journal ArticleDOI

Xylulose fermentation by Saccharomyces cerevisiae and xylose-fermenting yeast strains

S. Yu, +2 more
- 01 Dec 1995 - 
TL;DR: Xylulose fermentation by four strains of Saccharomyces cerevisiae and two strains of xylose-fermenting yeasts, Pichia stipitis CBS 6054 and Candida shehatae NJ 23, was compared using a mineral medium at a cell concentration of 10 g (dry weight)/l.
Journal ArticleDOI

Analysis of the hypoxia-induced ADH2 promoter of the respiratory yeast Pichia stipitis reveals a new mechanism for sensing of oxygen limitation in yeast.

Volkmar Passoth, +5 more
- 15 Jan 2003 - 
TL;DR: The very first promoter analysis in P. stipitis revealed a hitherto unknown mechanism of oxygen sensing in yeast, which has similarities to the mammalian HIF‐1 system, which is inducible by Co2+ but not by cyanide.
