Comparative xylose metabolism among the Ascomycetes C. albicans, S. stipitis and S. cerevisiae.

PLoS ONE, 2013
The ascomycetes Candida albicans, Saccharomyces cerevisiae and Scheffersomyces stipitis metabolize the pentose sugar xylose very differently. S. cerevisiae fails to grow on xylose, while C. albicans can grow, and S.

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

Asking the 5 W's for designing next‐generation bioprocessing

AIChE Journal, EarlyView.
Abstract Biotechnology is expanding beyond traditional, centralized fermentation and toward next‐generation bioprocessing paradigms that emphasize flexible deployment outside the laboratory with application‐specific performance. However, many bioprocesses fail to translate beyond proof‐of‐concept into industrially viable systems because early design ...

Insertion of a xylanase in xylose binding protein results in a xylose-stimulated xylanase [PDF]

Biotechnology for Biofuels, 2015
Product inhibition can reduce catalytic performance of enzymes used for biofuel production. Different mechanisms can cause this inhibition and, in most cases, the use of classical enzymology approach is not sufficient to overcome this problem. Here we have used a semi-rational protein fusion strategy to create a product-stimulated enzyme.

Effects of Lycium barbarum Residue Substituting Dietary Maize on Fecal Microbiota and Growth Performance of Crossbred Simmental Cattle

Animal Research and One Health, EarlyView.
The bioactive substances we extracted from Lycium barbarum residue (LBR) have a typical polysaccharide structure. When 1.80% LBR was used to replace maize in the diet, the average daily gain of rossbred Simmental was significantly increased, and anti‐inflammatory ability was improved. In addition, LBR improved the fecal microbial composition, increased

Determination of D-Xylose in Urine for the D-Xylose Absorption Test

Clinical Chemistry, 1969
Abstract A method is described for the determination of D-xylose in urine which is based on the specific absorptivity of the pentose o-toluidine complex. Quantitation of xylose can be made in the presence of a hexose.

Establishment of Acid Hydrolysis by Box–Behnken Methodology as Pretreatment to Obtain Reducing Sugars from Tiger Nut Byproducts

Agronomy, 2020
Carbohydrate-rich byproducts may be used as a growth substrate for microalgae. The tiger nut, compared to other tubers, has higher carbohydrate content, which mostly remain in the byproduct after the production of tiger nut milk (“Horchata”).

Harnessing plant‐based platform for low‐cost cellulosic sugar recovery from bioenergy crops

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The price of pure cellulase enzyme for the recovery of fermentable cellulosic sugars is one of the major challenges that limit the commercialization of second‐generation biofuels and bio‐based products. This work shows a means to greatly reduce the cost of cellulases. The abundant capacity of plants to synthesize and hyperaccumulate transgenic

Metabolic engineering and comparative performance studies of Synechocystis sp. PCC 6803 strains for effective utilization of xylose.

Frontiers in Microbiology, 2015
Wood sugars such as xylose can be used as an inexpensive carbon source for biotechnological applications. The model cyanobacterium Synechocystis sp. PCC 6803 lacks the ability to catabolize wood sugars as an energy source.

A Modular Nucleoside Kinase Cascade for the Synthesis of Ribonucleoside Triphosphates

Biotechnology and Bioengineering, EarlyView.
Damm et al. report standardized enzymatic cascades for production of all canonical nucleoside triphosphates from the corresponding nucleosides, using kinase‐catalyzed phosphorylation from acetyl phosphate. Reactions afforded ∼ 100 mM product in near‐quantitative conversion.
