Increased expression of the oxidative pentose phosphate pathway and gluconeogenesis in anaerobically growing xylose-utilizing Saccharomyces cerevisiae

Microbial Cell Factories, 2009
Background Fermentation of xylose to ethanol has been achieved in S. cerevisiae by genetic engineering. Xylose utilization is however slow compared to glucose, and during anaerobic conditions addition of glucose has been necessary for cellular growth. In

Xylose Metabolization by a Saccharomyces cerevisiae Strain Isolated in Colombia

Indian Journal of Microbiology, 2023
AbstractSaccharomyces cerevisiae (S. cerevisiae) is the most widely used yeast in biotechnology in the world because its well-known metabolism and physiology as well as its recognized ability to ferment sugars such as hexoses. However, it does not metabolize pentoses such as arabinose and xylose, which are present in lignocellulosic biomass ...

D-glucose overflow metabolism in an evolutionary engineered high-performance D-xylose consuming Saccharomyces cerevisiae strain [PDF]

, 2021
Co-consumption of D-xylose and D-glucose by Saccharomyces cerevisiae is essential for cost-efficient cellulosic bioethanol production. There is a need for improved sugar conversion rates to minimize fermentation times.

Xylose metabolism in the fungus Rhizopus oryzae : effect of growth and respiration on l (+)-lactic acid production

, 2008
The fungus Rhizopus oryzae converts both glucose and xylose under aerobic conditions into chirally pure l(+)-lactic acid with by-products such as xylitol, glycerol, ethanol, carbon dioxide and fungal biomass.

DataSheet_1_Dietary intake of xylose impacts the transcriptome and proteome of tissues involved in xylose metabolism in swine.zip

, 2023
Xylose is a primary component of arabinoxylan in swine diets. As arabinoxylan is a significant component of fiber, and fiber is generally rising in practical pig diets globally, the study of arabinoxylan and xylose is of increasing interest. However, the

Engineering xylose metabolism in yeasts to produce biofuels and chemicals

Current Opinion in Biotechnology, 2021
Xylose is the second most abundant sugar in lignocellulosic biomass. Efficient and rapid xylose utilization is essential for the economic bioconversion of lignocellulosic biomass into value-added products. Building on previous pathway engineering efforts to enable xylose fermentation in Saccharomyces cerevisiae, recent work has focused on reprogramming
