Analysis of a conserved cellulase transcriptional regulator reveals inducer-independent production of cellulolytic enzymes in Neurospora crassa. [PDF]

open access: yes, 2013
Cellulose is recalcitrant to deconstruction to glucose for use in fermentation strategies for biofuels and chemicals derived from lignocellulose. In Neurospora crassa, the transcriptional regulator, CLR-2, is required for cellulolytic gene expression and

Exploring the xylose paradox in Saccharomyces cerevisiae through in vivo sugar signalomics of targeted deletants

open access: yesMicrobial Cell Factories, 2019
BackgroundThere have been many successful strategies to implement xylose metabolism in Saccharomyces cerevisiae, but no effort has so far enabled xylose utilization at rates comparable to that of glucose (the preferred sugar of this yeast).

Optimization of second‐generation lactic acid from corn stover by alkaline catalysis in subcritical water reaction medium

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract The optimization of hydrothermal lactic acid (LA) production from corn stover using Ca(OH)2 as catalyst was investigated. Initial studies with a 9 g L−1 glucose solution, and different Ca(OH)2 concentrations, in the range of 0.025–0.1 M, identified 0.075 M as the optimal concentration.

Catalytic conversion of diformylxylose to furfural in biphasic solvent systems

open access: yesFrontiers in Bioengineering and Biotechnology, 2023
Biobased furfural is a sustainable alternative to petrochemical intermediates for bulk chemicals and fuel production. However, existing methods for the conversion of xylose or lignocelluloses in mono-/bi-phasic systems to furfural involve non-selective ...

Enhanced Furfural Yields from Xylose Dehydration in the γ-Valerolactone/Water Solvent System at Elevated Temperatures.

open access: yesChemSusChem, 2018
High yields of furfural (>90 %) were achieved from xylose dehydration in a sustainable solvent system composed of γ-valerolactone (GVL), a biomass derived solvent, and water.

Sequential fractionation and polyoxometalate‐catalyzed oxidation of lignocellulosic biomass improves cellulose purity and formic acid yield

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Lignocellulosic biomass is an important source of renewable chemicals and materials but its full valorization is necessary in order to achieve economic and sustainability goals. This study proposes a two‐step approach for the valorization of lignocellulosic biomass combining solvent‐assisted fractionation and catalytic oxidation with molecular

arrostii roots [PDF]

open access: yes, 2016
A new acylated and triterpenoidal saponin, named GS1, was isolated from the roots of Gypsophila arrostii Guss. On the basis of acid hydrolysis, comprehensive spectroscopic analyses and comparison with spectral data of known compounds, its structure was ...

Regulation of metabolism in Escherichia coli during growth on mixtures of the non-glucose sugars: arabinose, lactose, and xylose

open access: yesScientific Reports, 2018
Catabolite repression refers to the process where the metabolism of one sugar represses the genes involved in metabolizing another sugar. While glucose provides the canonical example, many other sugars are also known to induce catabolite repression ...

Development of a continuous intensified process for conversion of hemicellulose sugars into furans using an agitated cell reactor

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study addresses significant process challenges associated with the reactive nature of hemicellulose‐derived furan intermediates in aqueous mediums. A continuous agitated cell reactor was used to intensify the extractive reaction using methyl isobutyl ketone as an extractive phase to isolate in situ the furan products obtained by ...
