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]
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.

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]
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
Background Schizochytrium sp. is a heterotrophic, oil-producing microorganism that can efficiently produce lipids. However, the industrial production of bulk chemicals using Schizochytrium sp.

Crystallographic Studies of d-Xylose Isomerase [PDF]
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.

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]
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
