Different transcriptional responses of haploid and diploid S. cerevisiae strains to changes in cofactor preference of XR

Microbial Cell Factories, 2020
Background Xylitol accumulation is a major barrier for efficient ethanol production through heterologous xylose reductase-xylitol dehydrogenase (XR-XDH) pathway in recombinant Saccharomyces cerevisiae.

Metabolic engineering of Saccharomyces cerevisiae for second-generation ethanol production from xylo-oligosaccharides and acetate

Scientific Reports, 2023
Simultaneous intracellular depolymerization of xylo-oligosaccharides (XOS) and acetate fermentation by engineered Saccharomyces cerevisiae offers significant potential for more cost-effective second-generation (2G) ethanol production. In the present work,

A single amino acid change (Y318F) in the L-arabitol dehydrogenase (LadA) from Aspergillus niger results in a significant increase in affinity for D-sorbitol

BMC Microbiology, 2009
Background L-arabitol dehydrogenase (LAD) and xylitol dehydrogenase (XDH) are involved in the degradation of L-arabinose and D-xylose, which are among the most abundant monosaccharides on earth. Previous data demonstrated that LAD and XDH not only differ

Influence of L-lactate and low glucose concentrations on the metabolism and the toxin formation of Clostridioides difficile.

PLoS ONE, 2021
The virulence of Clostridioides difficile (formerly Clostridium difficile) is mainly caused by its two toxins A and B. Their formation is significantly regulated by metabolic processes.

Genetic analysis of D-xylose metabolism by endophytic yeast strains of Rhodotorula graminis and Rhodotorula mucilaginosa

Genetics and Molecular Biology, 2011
Two novel endophytic yeast strains, WP1 and PTD3, isolated from within the stems of poplar (Populus) trees, were genetically characterized with respect to their xylose metabolism genes. These two strains, belonging to the species Rhodotorula graminis and

Xylose metabolism in the fungus Rhizopus oryzae : effect of growth and respiration on l (+)-lactic acid production [PDF]

, 2008
The fungus Rhizopus oryzae converts both glucose and xylose under aerobic conditions into chirally pure l(+)-lactic acid with by-products such as xylitol, glycerol, ethanol, carbon dioxide and fungal biomass.

The potential use of xylitol in glucose-6-phosphate dehydrogenase deficiency anemia [PDF]

Journal of Clinical Investigation, 1971
NADP-linked xylitol dehydrogenase has been found to be present in human red blood cells. This enzyme activity is normal in most glucose-6-phosphate dehydrogenase (G6PD)-deficient red cells. Xylitol was explored as a potential agent for treatment of hemolysis in patients with G6PD-deficiency.

Cloning of the Xylitol Dehydrogenase Gene fromGluconobacter oxydansand Improved Production of Xylitol fromD-Arabitol

Bioscience, Biotechnology, and Biochemistry, 2003
Xylitol dehydrogenase (XDH) was purified from the cytoplasmic fraction of Gluconobacter oxydans ATCC 621. The purified enzyme reduced D-xylulose to xylitol in the presence of NADH with an optimum pH of around 5.0. Based on the determined NH2-terminal amino acid sequence, the gene encoding xdh was cloned, and its identity was confirmed by expression in ...

Single‐Step Production of Mannitol From Yacon Fructo‐Oligosaccharides Using Fructophilic Lactic Acid Bacteria

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
Mannitol is a sweetener with a low glycaemic index and calorific value that can be produced efficiently by bacterial transformation. We demonstrate its production by Leuconostoc mesenteroides and Fructobacillus fructophilus from a novel substrate, fructo‐oligosaccharides from the tuber yacon in a single‐step process that is amenable to scale‐up ...
