Xylitol Production From D-Xylose by Facultative Anaerobic Bacteria
… and Corynebacterium) were screened for the production of xylitol; a sugar alcohol used as a sweetener in the pharmaceutical and food industries. A chromogenic assay of both solid and liquid cultures showed that 10 of the 17 species screened could grow on D-xylose and produce detectable …

Optimizing xylitol production: a molecular and experimental study of xylose reductase in Candida tropicalis
Xylitol, a naturally occurring sugar alcohol, is widely used in the food and pharmaceutical industries as both an artificial sweetener and an anticariogenic agent. Traditional xylitol production relies on harsh chemicals and energy-intensive processes, making microbial fermentation a more …

Engineering robust yeast strains for the conversion of xylose derived from lignocellulosic biomass to xylitol
… ethanol. This can be realised with the co-production of the low-calorie sugar substitute, xylitol which has a well-established market, as well as other chemicals. The construction of a xylitolproducing S. cerevisiae strain represents an economically feasible and environmentally friendly …

Recovery of Xylitol from Fermentation of Model Hemicellulose Hydrolysates Using Membrane Technology
Xylitol can be produced from xylose or hemicellulose hydrolysates by either chemical reduction or microbial fermentation. Current technology for commercial production is based on chemical reduction of xylose or hemicellulose, and xylitol is separated and purified by chromatographic methods. The …

Engineering Zymomonas mobilis for the production of biofuels and other value-added products
… a promising organism for lignocellulosic biofuel production as it can efficiently produce ethanol from simple sugars using unique metabolic pathways. Z. mobilis displays what is known as the “uncoupled growth” phenomenon, meaning cells will rapidly convert sugars to ethanol regardless of their …

Systematic and combinatorial approaches for metabolic engineering of optimal yeast strains to produce fuels and chemicals
… broad applications for sustainable biological production of value-added fuels and chemicals. Initially, a systematic approach based on global reaction stoichiometry was applied to select gene knockout targets in Saccharomyces cerevisiae for enhancing bioethanol production from glucose with …

Engineering a Fungal L-Arabinose Pathway Towards the Co-Utilization of Hemicellulosic Sugars for Production of Xylitol
… to the organism’s evolution not dependent on the production of such high levels of desired product. Xylitol is an attractive pentose sugar alcohol that has many applications in the food, pharmaceutical, and high-value based biochemical product industries. It is still, however, relatively expensive …
