Biochemical routes for uptake and conversion of xylose by microorganisms

Biotechnology for Biofuels, 2020
Xylose is a major component of lignocellulose and the second most abundant sugar present in nature. Efficient utilization of xylose is required for the development of economically viable processes to produce biofuels and chemicals from biomass.

Biochemical production by Yarrowia lipolytica from Xylose [PDF]

, 2021
Xylose is the second most abundant sugar in cellulosic hydrolysate. Xylose utilization has been extensively studied in both microbes that naturally utilize it, for example Escherichia coli and Scheffersomyces stipitis, as well as in model organisms that ...

Increased expression of the oxidative pentose phosphate pathway and gluconeogenesis in anaerobically growing xylose-utilizing Saccharomyces cerevisiae

Microbial Cell Factories, 2009
Background Fermentation of xylose to ethanol has been achieved in S. cerevisiae by genetic engineering. Xylose utilization is however slow compared to glucose, and during anaerobic conditions addition of glucose has been necessary for cellular growth. In

Genome-scale consequences of cofactor balancing in engineered pentose utilization pathways in Saccharomyces cerevisiae. [PDF]

PLoS ONE, 2011
Biofuels derived from lignocellulosic biomass offer promising alternative renewable energy sources for transportation fuels. Significant effort has been made to engineer Saccharomyces cerevisiae to efficiently ferment pentose sugars such as D-xylose and ...

Utilization of d-ribose through d-xylose transporter [PDF]

FEMS Microbiology Letters, 1998
An Escherichia coli mutant defective in high-affinity D-ribose transport is able to utilize the sugar as a sole carbon source, suggesting that other transport systems for D-ribose exist. In order to search for such transporters, transposon mutagenesis was carried out in an rbsB-negative strain containing ribokinase (rbsK) for sugar phosphorylation ...

Comparison of heterologous xylose transporters in recombinant Saccharomyces cerevisiae

Biotechnology for Biofuels, 2010
Background Baker's yeast (Saccharomyces cerevisiae) has been engineered for xylose utilization to enable production of fuel ethanol from lignocellulose raw material. One unresolved challenge is that S.

Exploring the xylose paradox in Saccharomyces cerevisiae through in vivo sugar signalomics of targeted deletants

Microbial Cell Factories, 2019
Background There have been many successful strategies to implement xylose metabolism in Saccharomyces cerevisiae, but no effort has so far enabled xylose utilization at rates comparable to that of glucose (the preferred sugar of this yeast). Many studies
