Development of Sustainable Carbohydrate-Based Solvents by Acetal Functionalisation of Biomass

Organic solvents are ubiquitous in industrial and domestic applications from the production of pharmaceuticals to household consumer products. The negative impact of most traditional solvents, especially aprotic types, on the environment, health, and safet ...

Equilibrium and non-equilibrium furanose selection in the ribose isomerisation network

Paolo De Los Rios, Daniel Maria Busiello, Shiling Liang, Francesco Piazza

The exclusive presence of beta -D-ribofuranose in nucleic acids is still a conundrum in prebiotic chemistry, given that pyranose species are substantially more stable at equilibrium. However, a precise characterisation of the relative furanose/pyranose fra ...

Catalyst Evolution Enhances Production of Xylitol from Acetal-Stabilized Xylose

Jeremy Luterbacher, Masoud Talebi Amiri, Ydna Marie Questell-Santiago, Benjamin Pierre Le Monnier, Jher Hau Yeap

We demonstrate a catalytic process for xylitol production based on the volatility and unique reactivity of diformylxylose (DFX), which can be produced at near theoretical yield from biomass and, contrary to xylose, can be easily purified by distillation. T ...

Production, characterization and upgrading of biomass-derived acetal-stabilized carbohydrates

Ydna Marie Questell-Santiago

Biomass is an attractive source of renewable carbon-based fuels and chemicals. Multiple research efforts are centered around integrated biorefineries, where all fractions of biomass are converted to fuels or chemical products. These efforts are focused aro ...

Bioconversion of pentose sugars to value added chemicals and fuels: Recent trends, challenges and possibilities

Edgard Gnansounou, Vinod Kumar

Most of the crop plants contain about 30% of hemicelluloses comprising D-xylose and D-arabinose. One of the major limitation for the use of pentose sugars is that high purity grade D-xylose and D-arabinose are yet to be produced as commodity chemicals. Res ...

A mild biomass pretreatment using gamma-valerolactone for concentrated sugar production

Jeremy Luterbacher, Ydna Marie Questell-Santiago, Li Shuai

Here we report that gamma-valerolactone (GVL), a biomass-derived solvent, can be used to facilitate the mild pretreatment of lignocellulosic biomass. An 80% GVL, 20% water solvent system was used to pretreat hardwood at the mild temperature of 120 degrees ...

Improving Ethanol Production of Xylose-Utilizing Saccharomyces cerevisiae

Vassily Hatzimanikatis, Ljubisa Miskovic

Abundant in nature lignocellulosic plant biomass represent a promising, sustainable, source of energy as it can be converted into fuel ethanol through the fermentation of one of its prevalent sugar constituents – xylose. Xylose-utilizing recombinant Saccha ...

Structural and kinetic studies of induced fit in xylulose kinase from Escherichia coli

Henning Paul-Julius Stahlberg

The primary metabolic route for D-xylose, the second most abundant sugar in nature, is via the pentose phosphate pathway after a two-step or three-step conversion to xylulose-5-phosphate. Xylulose kinase (XK; EC 2.7.1.17) phosphorylates D-xylulose, the las ...

Synthesis and pairing properties of 3'-deoxyribopyranose (4' -> 2')-oligonucleotides ('p-DNA')

Damian Ackermann

The prepn. and the pairing properties of the new 3'-deoxyribopyranose (4'->2')-oligonucleotide (= p-DNA) pairing system, based on 3'-deoxy-b-D-ribo-pyranose nucleosides is presented. D-Xylose was efficiently converted to the prefunctionalized 3-deoxyribopy ...
