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.

Innovative of Second Generation Ethanol Production from Biomass Crops by Pichia Stipitis

Chemical Engineering Transactions, 2014
The production of ethanol from lignocellulosic material, as reported by Kumar (2009), consists of mainly five different steps, namely pretreatment, (enzymatic) hydrolysis, fermentation, product separation and post-treatment of the liquid fraction.

Comparative studies on the proteins, carbohydrates, acid phosphatase and ribonuclease in caryopses of two orchardgrass (Dactylis glomerata L.) varieties

Acta Societatis Botanicorum Poloniae, 2014
Comparative studies were carried out on some biochemical components in caryopses of two varieties of Dactylis glomerata. The determined protein content depended upon the solvent and amounted to 0.22-0.39 g, with sugar amounting to 2.7-3.6 g and pentoses ...

Conversion of pentoses by yeasts [PDF]

Biotechnology and Bioengineering, 1983
AbstractThe utilization and conversion of D‐xylose, D‐xylulose, L‐arabinose, and xylitol by yeast strains have been investigated with the following results: (1) The majority of yeasts tested utilize D‐xylose and produce polyols, ethanol, and organic acids. The type and amount of products formed varies with the yeast strains used.

Pentose metabolism in Mycobacterium smegmatis: specificity of induction of pentose isomerases [PDF]

Journal of Bacteriology, 1976
The induction of D-xylose, D-ribose, L-arabinose, and D-lyxose isomerases by various sugars was studied to determine the configuration necessary for induction. D-Xylose isomerase was only induced by D-xylose, whereas D-ribose isomerase was induced by D-ribose, L-rhamnose, and L-lyxose.

Influence of sugars on the reddening of triturated florets of dyer's saffron flowers

Acta Societatis Botanicorum Poloniae, 2014
Pentoses, hexoses and disaccharides were administered to the triturated florets of dyer's saffon (Carthamus tinctorius) and their effects on enzyme-catalyzed floret reddening examined spectrophotometically.

Influence of GA3 and NAA on certain carbohydrate fractions in corms of saffron crocus (Crocus sativus L.) during development

Acta Societatis Botanicorum Poloniae, 2014
Application of gibberellic acid (GA3) and napthaleneacetic acid (NAA) to corms of saffron crocus (Crocus sativus L.) markedly influenced degradation of reserve carbohydrates in the corm tissues.

A non-linear model of hydrogen production by Caldicellulosiruptor saccharolyticus for diauxic-like consumption of lignocellulosic sugar mixtures

Biotechnology for Biofuels, 2018
Background Caldicellulosiruptor saccharolyticus is an attractive hydrogen producer suitable for growth on various lignocellulosic substrates. The aim of this study was to quantify uptake of pentose and hexose monosaccharides in an industrial substrate ...

Seasonal Changes in the Carbohydrate Pool of an Atlantic Forest Soil under Different Vegetation Types Variación estacional de los carbohidratos en un suelo forestal de la región atlántica desarrollado bajo diferentes tipos de vegetación Variação sazonal dos hidratos de carbono num solo florestal da região Atlântica desenvolvido sob diferentes tipos de vegetação [PDF]

Spanish Journal of Soil Science, 2011
<p>The seasonal variations of the content and composition of soil carbohydrates, a labile pool of the soil organic matter, were studied in a Humic Cambisol located within the Atlantic temperate-humid zone (Galicia, N.W. of Spain) and developed over
