Novel xylose transporter Cs4130 expands the sugar uptake repertoire in recombinantSaccharomyces cerevisiaestrains at high xylose concentrations
(Bmc, 2020-08-14)
Background The need to restructure the world's energy matrix based on fossil fuels and mitigate greenhouse gas emissions stimulated the development of new biobased technologies for renewable energy. One promising and cleaner ...
Cloning and overexpression of the xylose isomerase gene from Burkholderia sacchari and production of polyhydroxybutyrate from xylose
(NATL RESEARCH COUNCIL CANADA-N R C RESEARCH PRESS, 2009)
A different organization for the xyl operon was found in different genomes of Burkholderia and Pseudomomas species. Degenerated primers were designed based on Burkholderia genomes and used to amplify the xylose isomerase ...
High xylose yield from stem and external fraction of sugarcane biomass by diluted acid pretreatment
(2020-01-01)
Lignocellulosic materials are complex, recalcitrant, and difficult to release fermentable carbohydrates, such as xylose. Xylose is the feedstock for the development of products with high added value, such as ethanol, ...
Expression, purification, crystallization and preliminary X-ray diffraction analysis of Bifidobacterium adolescentis xylose isomerase
(International Union of Crystallography - IUCrChester, 2013-05)
Xylose isomerase (EC 5.3.1.5) is a key enzyme in xylose metabolism which is industrially important for the transformation of glucose and xylose into fructose and xylulose, respectively. The Bifidobacterium adolescentis ...
The isolation of pentose-assimilating yeasts and their xylose fermentation potential
(2018-01-01)
For the implementation of cellulosic ethanol technology, the maximum use of lignocellulosic materials is important to increase efficiency and to reduce costs. In this context, appropriate use of the pentose released by ...
Functional characterization of a xylose transporter in Aspergillus nidulans
(2014)
Abstract
Background
The production of bioethanol from lignocellulosic feedstocks will only become economically feasible when the majority of cellulosic ...
Establishment of the optimum initial xylose concentration and nutritional supplementation of brewer`s spent grain hydrolysate for xylitol production by Candida guilliermondii
(ELSEVIER SCI LTD, 2008)
The effects of initial xylose concentration and nutritional supplementation of brewer`s spent grain hydrolysate on xylitol production by Candida guilliermondii were evaluated using experimental design methodology. The ...
Inhibitory action of toxic compounds present in lignocellulosic hydrolysates on xylose to xylitol bioconversion by Candida guilliermondii
(SPRINGER HEIDELBERG, 2011)
The inhibitory action of acetic acid, ferulic acid, and syringaldehyde on metabolism of Candida guilliermondii yeast during xylose to xylitol bioconversion was evaluated. Assays were performed in buffered and nonbuffered ...
KINETICS OF OXIDATION OF D-ARABINOSE AND D-XYLOSE BY VANADIUM (V) IN THE PRESENCE OF MANGANESE II AS HOMOGENEOUS CATALYST
(Sociedad Chilena de Química, 2010)
Role of Glycerol Addition on Xylose-to-Xylitol Bioconversion by Candida guilliermondii
(SPRINGER, 2009)
The effect of glycerol on xylose-to-xylitol bioconversion by Candida guilliermondii was evaluated by its addition (0.7 and 6.5 g/l) to semidefined media (xylose as a substrate). The glycerol concentrations were chosen based ...
