Background Two heterologous pathways have been used to construct recombinant xylose-
fermenting Saccharomyces cerevisiae strains: i) the xylose reductase (XR) and xylitol …

The heterologous expression of a highly functional xylose isomerase pathway in
Saccharomyces cerevisiae would have significant advantages for ethanol yield, since the …

Agricultural residues rich in carbohydrate content, such as hemicellulose, are produced in
large amounts annually world-wide. These biological byproducts, which are wastes, can be …

Xylose is the second most abundant sugar in lignocellulosic biomass. Efficient and rapid
xylose utilization is essential for the economic bioconversion of lignocellulosic biomass into …

Xylans from hemicelluloses can be depolymerized into xylose for the bioproduction of xylitol.
Xylitol is used as a sweetening agent, and it can be an important platform for sustainable …

Abstract Objectives To genetically engineer Saccharomyces cerevisiae for improved ethanol
productivity from glucose/xylose mixtures. Results An endogenous gene cassette composed …

Metabolic engineering of Saccharomyces cerevisiae for ethanol production from d-xylose,
an abundant sugar in plant biomass hydrolysates, has been pursued vigorously for the past …

Highlights•The potential of Y. lipolytica and R. toruloides for xylose and acetate
utilization.•Intense multi-omics analysis has been carried out under xylose/acetate …

An Escherichia coli strain, ZUC99 (pATX210), which can produce xylitol from l-arabinose at
a high yield, has been created by introducing a new bioconversion pathway into the cells …

1. Introduction Xylitol is a polyalcoholic sugar with five carbon atoms which is found naturally
in fruits and vegetables albeit in small quantity. Xylitol has similiar sweetness to sucrose, but …
