Sustainable Hydrogen Production by Glycerol and Monosaccharides Catalytic Acceptorless Dehydrogenation (AD) in Homogeneous Phase

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Sustainable hydrogen production can be obtained from hydogen‐rich biomass‐derived organic molecules through Acceptorless Dehydrogenation (AD) reactions. Glycerol and sugars are available in large quantities from industry and can be successfully used as substrates in AD protocols, in the presence of tailored, selective, easily tunable and thermally ...

Intestinal Transport of D-Xylose.

open access: yesExperimental Biology and Medicine, 1965
SummaryThe intestinal transport of D-Xylose was studied in the rat using 2 different methods of in situ perfusion. The absorption of xylose is inhibited by the presence in the perfusate of any of the following substances (listed in decreasing order of their inhibitory ability): phlorizin > glucose > 3-0-methylglucose > fructose > 3-0-methyl-fructose ...

Evaluation of the Simultaneous Production of Xylitol and Ethanol from Sisal Fiber

open access: yesBiomolecules, 2018
Recent years have seen an increase in the use of lignocellulosic materials in the development of bioproducts. Because sisal fiber is a low cost raw material and is readily available, this work aimed to evaluate its hemicellulose fraction for the ...

Xylose Acetals ‐ a New Class of Sustainable Solvents and Their Application in Enzymatic Polycondensation

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...

Improvement of Xylose Fermentation Ability under Heat and Acid Co-Stress in Saccharomyces cerevisiae Using Genome Shuffling Technique

open access: yesFrontiers in Bioengineering and Biotechnology, 2017
Xylose-assimilating yeasts with tolerance to both fermentation inhibitors (such as weak organic acids) and high temperature are required for cost-effective simultaneous saccharification and cofermentation (SSCF) of lignocellulosic materials.

Biotransformation of Phenolics in Spent Liquor from Aqueous Ammonia Pretreatment

open access: yesChemSusChem, EarlyView.
Aqueous ammonia pretreatment of poplar releases p‐hydroxybenzamide (pHBAm) and p‐hydroxybenzoic acid (pHBA) into the spent liquor and converts some of the pHBA to phenol. An engineered strain of N. aromaticivorans transforms pHBAm and pHBA into the bioplastic precurso 2‐pyrone‐4,6‐dicarboxylic acid.

Boosting POM‐Ionosolv Biorefining of Lignocellulosic Biomass by Using Redox‐Balanced Polyoxometalate Catalysts in Methanolic Ionic Liquid Reaction Media

open access: yesChemSusChem, EarlyView.
This study presents an advanced iteration of the polyoxometalate (POM)‐Ionosolv concept to generate biobased methyl formate in high yield and a bleached cellulose pulp from lignocellulosic biomass in a single‐step operation by using redox‐balanced POM catalysts and molecular oxygen in alcoholic ionic liquid mixtures.

Engineering Xylose Isomerase and Reductase Pathways in Yarrowia lipolytica for Efficient Lipid Production

open access: yesMicrobial Biotechnology
Xylose is a common monosaccharide in lignocellulosic residues that Yarrowia lipolytica cannot naturally metabolise for lipid production and therefore, heterologous xylose metabolic pathways must be engineered in this yeast to facilitate its consumption ...
