Functional characterization of a highly specific l-arabinose transporter from Trichoderma reesei

Microbial Cell Factories, 2021
Background Lignocellulose biomass has been investigated as a feedstock for second generation biofuels and other value-added products. Some of the processes for biofuel production utilize cellulases and hemicellulases to convert the lignocellulosic ...

Characterization of simultaneous uptake of xylose and glucose in Caldicellulosiruptor kronotskyensis for optimal hydrogen production

Biotechnology for Biofuels, 2021
Background Caldicellulosiruptor kronotskyensis has gained interest for its ability to grow on various lignocellulosic biomass. The aim of this study was to investigate the growth profiles of C. kronotskyensis in the presence of mixtures of glucose–xylose.

Engineering of sugar transporters for improvement of xylose utilization during high-temperature alcoholic fermentation in Ogataea polymorpha yeast

Microbial Cell Factories, 2020
Background Xylose transport is one of the bottlenecks in the conversion of lignocellulosic biomass to ethanol. Xylose consumption by the wild-type strains of xylose-utilizing yeasts occurs once glucose is depleted resulting in a long fermentation process

Hydrogen-deuterium exchange mass spectrometry captures distinct dynamics upon substrate and inhibitor binding to a transporter

Nature Communications, 2020
XylE is a bacterial xylose transporter and homologue of human glucose transporters GLUTs 1-4. HDX-MS, mutagenesis and MD simulations suggest that protonation of a conserved aspartate triggers conformational transition from outward- to inward facing state

Engineering of Pentose Transport in Saccharomyces cerevisiae for Biotechnological Applications

Frontiers in Bioengineering and Biotechnology, 2020
Lignocellulosic biomass yields after hydrolysis, besides the hexose D-glucose, D-xylose, and L-arabinose as main pentose sugars. In second generation bioethanol production utilizing the yeast Saccharomyces cerevisiae, it is critical that all three sugars

Intestinal Transport of D-Xylose.

Experimental 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 ...

Co-utilization of L-arabinose and D-xylose by laboratory and industrial Saccharomyces cerevisiae strains [PDF]

, 2006
Background Fermentation of lignocellulosic biomass is an attractive alternative for the production of bioethanol. Traditionally, the yeast Saccharomyces cerevisiae is used in industrial ethanol fermentations. However, S.

Reprogramming a Hgt-family Kluyveromyces marxianus sugar transporter by site-directed mutagenesis to enable co-consumption of glucose and xylose. [PDF]

FEMS Yeast Res
Efficient utilization of lignocellulosic hydrolysates in yeast-based biorefineries requires simultaneous consumption of glucose and xylose, which is often limited by preferential glucose uptake.

Development of a D-xylose fermenting and inhibitor tolerant industrial Saccharomyces cerevisiae strain with high performance in lignocellulose hydrolysates using metabolic and evolutionary engineering [PDF]

, 2013
Background: The production of bioethanol from lignocellulose hydrolysates requires a robust, D-xylose-fermenting and inhibitor-tolerant microorganism as catalyst.

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.
