Combining Xylose Reductase from Spathaspora arborariae with Xylitol Dehydrogenase from Spathaspora passalidarum to Promote Xylose Consumption and Fermentation into Xylitol by Saccharomyces cerevisiae

Fermentation, 2020
In recent years, many novel xylose-fermenting yeasts belonging to the new genus Spathaspora have been isolated from the gut of wood-feeding insects and/or wood-decaying substrates.

The Weimberg pathway: an alternative for Myceliophthora thermophila to utilize d-xylose

Biotechnology for Biofuels and Bioproducts, 2023
Background With d-xylose being the second most abundant sugar in nature, its conversion into products could significantly improve biomass-based process economy. There are two well-studied phosphorylative pathways for d-xylose metabolism. One is isomerase

Comparing the xylose reductase/xylitol dehydrogenase and xylose isomerase pathways in arabinose and xylose fermenting Saccharomyces cerevisiae strains

Biotechnology for Biofuels, 2008
Background Ethanolic fermentation of lignocellulosic biomass is a sustainable option for the production of bioethanol. This process would greatly benefit from recombinant Saccharomyces cerevisiae strains also able to ferment, besides the hexose sugar ...

Genetic analysis of D-xylose metabolism by endophytic yeast strains of Rhodotorula graminis and Rhodotorula mucilaginosa

Genetics and Molecular Biology, 2011
Two novel endophytic yeast strains, WP1 and PTD3, isolated from within the stems of poplar (Populus) trees, were genetically characterized with respect to their xylose metabolism genes. These two strains, belonging to the species Rhodotorula graminis and

Pichia stipitis xylose reductase helps detoxifying lignocellulosic hydrolysate by reducing 5-hydroxymethyl-furfural (HMF)

Biotechnology for Biofuels, 2008
Background Pichia stipitis xylose reductase (Ps-XR) has been used to design Saccharomyces cerevisiae strains that are able to ferment xylose. One example is the industrial S. cerevisiae xylose-consuming strain TMB3400, which was constructed by expression

Balance of XYL1 and XYL2 expression in different yeast chassis for improved xylose fermentation

Frontiers in Microbiology, 2012
Reducing xylitol formation is an important step in engineering xylose reductase/xylitol dehydrogenase pathway for ethanol production from xylose in Saccharomyces cerevisiae. In this study, to balance the expression of XYL1 and mutant XYL2 encoding xylose

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

Microbial Cell Factories, 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.

Overview of Catalytic Properties of Fungal Xylose Reductases and Molecular Engineering Approaches for Improved Xylose Utilisation in Yeast

Applied Food Biotechnology, 2018
Background and Objective: Xylose reductases belong to the aldo-keto reductase family of enzymes, which catalyse the conversion of xylose to xylitol. Yeast xylose reductases have been intensively studied in the last two decades due to their significance ...

Novel pentose-regulated promoter of Aspergillus oryzae with application in controlling heterologous gene expression

Biotechnology Reports, 2022
The potent promoter and its transcriptional control make a significant contribution to strain optimization. Using transcriptome-based approach, a novel pentose-regulated promoter of the xylose reductase gene (PxyrA) of Aspergillus oryzae was identified ...
