Immobilization, Characterization and Application of a Xylose Isomerase Biocatalyst for Xylose Fermentation in Biorefineries

open access: yesFermentation
A biocatalyst has been developed for application in the simultaneous isomerization and fermentation (SIF) of xylose, which could enable operation in repeated batches and the use of xylose from biomass hemicellulose for the production of second-generation

Efficient calcium fumarate overproduction from xylose and corncob-derived xylose by engineered strains of Aureobasidium pullulans var. Aubasidani DH177 [PDF]

open access: yesMicrobial Cell Factories
Background Xylose from lignocellulose is one of the most abundant and important renewable and green raw materials. It is very important how to efficiently transform xylose into useful bioproducts such as fumaric acid and so on.

Development of Efficient Xylose Fermentation in Saccharomyces cerevisiae: Xylose Isomerase as a Key Component

open access: green, 2007
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 15 years. Whereas wild-type S. cerevisiae cannot ferment D-xylose, the keto-isomer D-xylulose can be metabolised slowly.

Restoration of a Defective Lactococcus lactis Xylose Isomerase [PDF]

open access: greenApplied and Environmental Microbiology, 2004
ABSTRACT The genes ( xylA ) encoding xylose isomerase (XI) from two Lactococcus lactis subsp. lactis strains, 210 (Xyl − ) and IO-1 (Xyl + ), were cloned, and the activities of their expressed proteins in ...

Engineering the xylose metabolism in Schizochytrium sp. to improve the utilization of lignocellulose

open access: yesBiotechnology for Biofuels and Bioproducts, 2022
Background Schizochytrium sp. is a heterotrophic, oil-producing microorganism that can efficiently produce lipids. However, the industrial production of bulk chemicals using Schizochytrium sp.

Identification of Mutations Responsible for Improved Xylose Utilization in an Adapted Xylose Isomerase Expressing Saccharomyces cerevisiae Strain

open access: yesFermentation, 2022
Economic conversion of biomass to biofuels and chemicals requires efficient and complete utilization of xylose. Saccharomyces cerevisiae strains engineered for xylose utilization are still considerably limited in their overall ability to metabolize ...

Crystallographic Studies of d-Xylose Isomerase [PDF]

open access: yesJournal of Biological Chemistry, 1974
In order to emphasize the similarity of the unit cell and of the diffraction patterns, this convention is only followed for Form B. The estimated error in unit cell measurements is 0.05 A for Form A crystals and 0.15 A for Form B crystals. The determined densities were reproducible within 0.02 g per cc.

Metabolic engineering considerations for the heterologous expression of xylose-catabolic pathways in Saccharomyces cerevisiae.

open access: yesPLoS ONE, 2020
Xylose, the second most abundant sugar in lignocellulosic biomass hydrolysates, can be fermented by Saccharomyces cerevisiae expressing one of two heterologous xylose pathways: a xylose oxidoreductase pathway and a xylose isomerase pathway.

Engineering and two-stage evolution of a lignocellulosic hydrolysate-tolerant Saccharomyces cerevisiae strain for anaerobic fermentation of xylose from AFEX pretreated corn stover. [PDF]

open access: yesPLoS ONE, 2014
The inability of the yeast Saccharomyces cerevisiae to ferment xylose effectively under anaerobic conditions is a major barrier to economical production of lignocellulosic biofuels. Although genetic approaches have enabled engineering of S. cerevisiae to
