Integration of metabolic and evolutionary processes to construct efficient xylose-utilizing strain of Zymomonas mobilis for lignocellulosic ethanol production

Synthetic and Systems Biotechnology
Xylose is a major component of lignocellulose, and it is crucial to enable microorganisms the capability of efficient xylose utilization for economical lignocellulosic biochemical production.

Identification of a glucose-insensitive variant of Gal2 from Saccharomyces cerevisiae exhibiting a high pentose transport capacity

Scientific Reports, 2021
As abundant carbohydrates in renewable feedstocks, such as pectin-rich and lignocellulosic hydrolysates, the pentoses arabinose and xylose are regarded as important substrates for production of biofuels and chemicals by engineered microbial hosts.

Biochemical production by Yarrowia lipolytica from Xylose [PDF]

, 2021
Xylose is the second most abundant sugar in cellulosic hydrolysate. Xylose utilization has been extensively studied in both microbes that naturally utilize it, for example Escherichia coli and Scheffersomyces stipitis, as well as in model organisms that ...

Utilization of d-ribose through d-xylose transporter [PDF]

FEMS Microbiology Letters, 1998
An Escherichia coli mutant defective in high-affinity D-ribose transport is able to utilize the sugar as a sole carbon source, suggesting that other transport systems for D-ribose exist. In order to search for such transporters, transposon mutagenesis was carried out in an rbsB-negative strain containing ribokinase (rbsK) for sugar phosphorylation ...

The role of hexose transporter-like sensor hxs1 and transcription activator involved in carbohydrate sensing azf1 in xylose and glucose fermentation in the thermotolerant yeast Ogataea polymorpha

Microbial Cell Factories, 2022
Background Fuel ethanol from lignocellulose could be important source of renewable energy. However, to make the process feasible, more efficient microbial fermentation of pentose sugars, mainly xylose, should be achieved.

Proton-linked D-xylose transport in Escherichia coli [PDF]

Journal of Bacteriology, 1980
The addition of xylose to energy-depleted cells of Escherichia coli elicited an alkaline pH change which failed to appear in the presence of uncoupling agents. Accumulation of [14C]xylose by energy-replete cells was also inhibited by uncoupling agents, but not by fluoride or arsenate. Subcellular vesicles of E.

Thermodynamic and Kinetic Modeling of Co-utilization of Glucose and Xylose for 2,3-BDO Production by Zymomonas mobilis

Frontiers in Bioengineering and Biotechnology, 2021
Prior engineering of the ethanologen Zymomonas mobilis has enabled it to metabolize xylose and to produce 2,3-butanediol (2,3-BDO) as a dominant fermentation product.

Biobased Sunflower Stalk Matrix for Lipase Stabilization via Physical Adsorption

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT The search for sustainable, cost‐effective biocatalytic processes has driven efforts to develop low‐cost supports for enzyme immobilization. Lignocellulosic residues have received particular attention due to their abundance, renewability, and structural properties.
