Kinetic studies on glucose and xylose transport in Saccharomyces cerevisiae

Applied Microbiology and Biotechnology, 2002
Zero trans-influx assays of glucose and xylose were performed using Saccharomyces cerevisiae to investigate transport characteristics under high and low glucose conditions. Under high glucose conditions, most glucose was transported by the low-affinity transporter.

Xylose transport in yeast for lignocellulosic ethanol production: Current status

Journal of Bioscience and Bioengineering, 2018
Lignocellulosic ethanol has been considered as an alternative transportation fuel. Utilization of hemicellulosic fraction in lignocelluloses is crucial in economical production of lignocellulosic ethanol. However, this fraction has not efficiently been utilized by traditional yeast Saccharomyces cerevisiae. Genetically modified S. cerevisiae, which can

Transport of D-xylose and sugar space in baker's yeast

Folia Microbiologica, 1963
The cell volume fraction ofSaccharomyces cerevisiae accessible tod-xylose and other nonmetabolized sugars was found to correspond to 100% of cell water in resting yeast over a range of osmolarities of the medium. This sugar space was decreased to 60% by nitrogen deficiency and to 82% by phosphorus deficiency.

d-xylose active transport in the hamster small intestine

Biochimica et Biophysica Acta (BBA) - Biophysics including Photosynthesis, 1966
Abstract D -Xylose is accumulated by rings of hamster small intestine, in vitro, through the same equilibrating mobile-carrier mechanism involved in glucose active transport. It is not necessary to postulate the presence of a distinct accumulation step in order to explain energy-dependent sugar accumulation. The experimental evidence is as follows:

Characterization of the effectiveness of hexose transporters for transporting xylose during glucose and xylose co‐fermentation by a recombinant Saccharomyces yeast

Yeast, 2004
AbstractWe have developed recombinant Saccharomyces yeasts that can effectively co‐ferment glucose and xylose to ethanol. However, these yeasts still ferment glucose more efficiently than xylose. The transport of xylose could be one of the steps limiting the fermentation of xylose.

Xylose Transport by the Anaerobic Thermophile Thermoanaerobacter ethanolicus and the Characterization of a D-Xylose-Binding Protein

Current Microbiology, 1998
Thermoanaerobacter ethanolicus is a xylose-utilizing thermophilic anaerobe that produces considerable amounts of ethanol. A protein in xylose-growing cells was solubilized from cell membranes by extraction with octyl-beta-glucoside. Internal peptide sequencing revealed that the protein was the product of a gene, xylF, encoding a putative D-xylose ...

[D-xylose transport in cultured mammalian cells].

Tsitologiia, 1980
The uptake of D-xylose by CHO-K1 cells in monolayer conditions, and by suspended L- and HeLa cells has been studied. The initial velocity is a function of exogenous xylose concentration. The estimated kinetic constants, Km and Vmax, at 37 degrees were, resp., 20 mM and 10 mmol/min for CHO cells, 12.5 mM and 2.8 mmol/min for L-cells, and at 16 degrees ...
