Regulation of Sugar Metabolism During Fermentation of Brewers' Spent Grain by Leuconostoc pseudomesenteroides DSM20193. [PDF]

open access: yesMicrob Biotechnol
This study reveals the regulatory mechanism behind sugar metabolism and dextran synthesis by Leuconostoc pseudomesenteroides DSM20193 during the fermentation of a complex substrate like brewers spent grain. Understanding metabolic pathways and genetic adaptation of lactic acid bacteria in food environments can help develop fermented products with ...

Xylose fermentation efficiency of industrial Saccharomyces cerevisiae yeast with separate or combined xylose reductase/xylitol dehydrogenase and xylose isomerase pathways [PDF]

open access: yesBiotechnology for Biofuels, 2019
Background Xylose isomerase (XI) and xylose reductase/xylitol dehydrogenase (XR/XDH) pathways have been extensively used to confer xylose assimilation capacity to Saccharomyces cerevisiae and tackle one of the major bottlenecks in the attainment of ...

Structural Analysis of Xylose Isomerase from Streptomyces avermitilis [PDF]

open access: goldCrystals
Xylose isomerase (XI, also known as glucose isomerase) is an oxidoreductase that interconverts aldoses and ketoses. XI catalyzes the reversible isomerization of D-glucose and D-xylose into D-fructose and D-xylulose, respectively.

Overexpression of Transketolase Relieves xylA Repression and Enhances Xylose Utilization in Saccharomyces cerevisiae During Mixed Sugar Fermentation

open access: yesGCB Bioenergy
Metabolic engineering of Saccharomyces cerevisiae has enabled xylose‐fermenting yeast strains. However, the bioavailability dilemma of xylose has become the core bottleneck restricting the economy of lignocellulose.

Comparison of the xylose reductase-xylitol dehydrogenase and the xylose isomerase pathways for xylose fermentation by recombinant Saccharomyces cerevisiae [PDF]

open access: yesMicrobial Cell Factories, 2007
Background Two heterologous pathways have been used to construct recombinant xylose-fermenting Saccharomyces cerevisiae strains: i) the xylose reductase (XR) and xylitol dehydrogenase (XDH) pathway and ii) the xylose isomerase (XI) pathway.

Genome sequence of carboxylesterase, carboxylase and xylose isomerase producing alkaliphilic haloarchaeon Haloterrigena turkmenica WANU15 [PDF]

open access: yesGenomics Data, 2016
We report draft genome sequence of Haloterrigena turkmenica strain WANU15, isolated from Soda Lake. The draft genome size is 2,950,899 bp with a G + C content of 64% and contains 49 RNA sequence.

Engineering the substrate specificity of xylose isomerase [PDF]

open access: bronzeProtein Engineering Design and Selection, 2005
Xylose isomerase (XI) catalyzes the isomerization and epimerization of hexoses, pentoses and tetroses. In order to clarify the reasons for the low reaction efficiency of a pentose sugar, L-arabinose, we determined the crystal structure of Streptomyces rubiginosus XI complexed with L-arabinose.

Mining Xylose Isomerase Producing Microbes [PDF]

open access: hybridMadras Agricultural Journal, 2020
An aerobic, rod shaped, mesophilic, gram positive xylitol producing bacterial isolates were made from different enriched substrates. Xylose isomerase is an enzyme that catalyzes the interconversion of D-xylose and D-xylulose. The microbes producing xylulose from xylose via xylose isomerase enzyme were screened for the xylose isomerase activity based on
