Inducible xylitol dehydrogenases in enteric bacteria [PDF]

Journal of Bacteriology, 1985
Morganella morganii ATCC 25829, Providencia stuartii ATCC 25827, Serratia marcescens ATCC 13880, and Erwinia sp. strain 4D2P were found to induce a xylitol dehydrogenase when grown on a xylitol-containing medium. The xylitol dehydrogenases were partially purified from the four strains, and those from M. morganii ATCC 25829, P.

Identification of genes involved in xylose metabolism of Meyerozyma guilliermondii and their genetic engineering for increased xylitol production

AMB Express, 2020
Meyerozyma guilliermondii, a non-conventional yeast that naturally assimilates xylose, is considered as a candidate for biotechnological production of the sugar alternative xylitol. Because the genes of the xylose metabolism were yet unknown, all efforts

Xylitol enhances synthesis of propionate in the colon via cross-feeding of gut microbiota

Microbiome, 2021
Background Xylitol, a white or transparent polyol or sugar alcohol, is digestible by colonic microorganisms and promotes the proliferation of beneficial bacteria and the production of short-chain fatty acids (SCFAs), but the mechanism underlying these ...

Structure-Guided Engineering of Xylitol Dehydrogenase Cosubstrate Specificity [PDF]

Structure, 2006
Xylitol dehydrogenase (XDH) is one of several enzymes responsible for assimilating xylose into eukaryotic metabolism and is useful for fermentation of xylose contained in agricultural byproducts to produce ethanol. For efficient xylose utilization at high flux rates, cosubstrates should be recycled between the NAD+-specific XDH and the NADPH-preferring

Molecular evolutionary insight of structural zinc atom in yeast xylitol dehydrogenases and its application in bioethanol production by lignocellulosic biomass

Scientific Reports, 2023
Xylitol dehydrogenase (XDH) catalyzes the NAD+-dependent oxidization of xylitol into d-xylulose, and belongs to a zinc-dependent medium-chain dehydrogenase/reductase family.

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 ...

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

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.

Production of Xylitol from d -Xylose by a Xylitol Dehydrogenase Gene-Disrupted Mutant of Candida tropicalis [PDF]

Applied and Environmental Microbiology, 2006
ABSTRACT Xylitol dehydrogenase (XDH) is one of the key enzymes in d -xylose metabolism, catalyzing the oxidation of xylitol to d -xylulose. Two copies of the XYL2 gene encoding XDH in the diploid yeast Candida tropicalis were ...
