Structural insight into D-xylose utilization by xylose reductase from Scheffersomyces stipitis [PDF]

Scientific Reports, 2018
AbstractLignocellulosic biomass, of which D-xylose accounts for approximately 35% of the total sugar, has attracted attention as a future energy source for biofuel. To elucidate molecular mechanism of D-xylose utilization, we determined the crystal structure of D-xylose reductase from Schefferzomyces stipitis (SsXR) at a 1.95 Å resolution.

An evolved xylose transporter from Zymomonas mobilis enhances sugar transport in Escherichia coli

Microbial Cell Factories, 2009
Background Xylose is a second most abundant sugar component of lignocellulose besides glucose. Efficient fermentation of xylose is important for the economics of biomass-based biorefineries.

Nicotine Reprograms Aging‐Related Metabolism and Protects Against Motor Decline in Mice

Advanced Science, EarlyView.
Long‐term oral nicotine intake protects against age‐related motor decline in mice without eliciting systemic toxicity. Integrated multi‐organ metabolomic profiling and longitudinal gut microbiota analyses reveal that nicotine induces coordinated remodeling of glycolipid and sphingolipid metabolism, enhances NAD⁺ bioavailability, and suppresses ceramide

Urinary xylose excretion in steatorrhoea [PDF]

Gut, 1962
The urinary xylose excretion is low in patients with untreated idiopathic steatorrhoea but subsequent improvement in excretion was noted after treatment in six out of nine patients. This did not coincide with histological improvement. With Crohn's disease low values were found when the jejunum but not the ileum was involved.

Xylose: absorption, fermentation, and post-absorptive metabolism in the pig

Journal of Animal Science and Biotechnology, 2018
Xylose, as β-1,4-linked xylan, makes up much of the hemicellulose in cell walls of cereal carbohydrates fed to pigs. As inclusion of fibrous ingredients in swine diets continues to increase, supplementation of carbohydrases, such as xylanase, is of ...

Xylose Metabolism Perturbation in Yarrowia lipolytica for Efficient Succinic Acid Bioproduction from Lignocellulosic Biomass

Advanced Science, EarlyView.
This study engineers Yarrowia lipolytica to produce succinic acid (SA) from lignocellulosic biomass. Adaptive evolution and multi‐omics analysis identify regulators that alleviate xylose metabolic disorder. Multi‐copy integration of xylose metabolic genes resolves redox imbalances from a futile fatty acid cycle, producing high‐titer SA from corn stover

Xylitol production from xylose mother liquor: a novel strategy that combines the use of recombinant Bacillus subtilis and Candida maltosa

Microbial Cell Factories, 2011
Background Xylose mother liquor has high concentrations of xylose (35%-40%) as well as other sugars such as L-arabinose (10%-15%), galactose (8%-10%), glucose (8%-10%), and other minor sugars.

New xylose transporters support the simultaneous consumption of glucose and xylose in Escherichia coli

mLife, 2022
Glucose and xylose are two major components of lignocellulose. Simultaneous consumption of glucose and xylose is critical for engineered microorganisms to produce fuels and chemicals from lignocellulosic biomass. Although many production limitations have
