Stereodivergent C‐(Hetero)Aryl Glycosylation by Nickel‐Catalyzed Redox‐Neutral Cross‐Coupling of Glycosyl Sulfonyl Hydrazides

Angewandte Chemie, EarlyView.
A nickel‐catalyzed C–C cross‐coupling protocol employing bench‐stable glycosyl sulfonyl hydrazides as practical glycosyl radical precursors is reported. A variety of (hetero)aryl iodides underwent cross‐coupling under redox‐neutral conditions to afford structurally diverse unprotected C‐(hetero)aryl glycosides.

Structure-based directed evolution improves S. cerevisiae growth on xylose by influencing in vivo enzyme performance

Biotechnology for Biofuels, 2020
Background Efficient bioethanol production from hemicellulose feedstocks by Saccharomyces cerevisiae requires xylose utilization. Whereas S. cerevisiae does not metabolize xylose, engineered strains that express xylose isomerase can metabolize xylose by ...

Role of xylose from acidic hydrolysates of agave bagasse during biohydrogen production

Water Science and Technology, 2021
This study compares the H2 production from glucose, xylose, and acidic hydrolysates of Agave tequilana bagasse as substrates. The fermentation was performed in a granular sludge reactor operated in two phases: (1) model substrates (glucose and xylose ...

d-xylose accelerated death of pentose metabolizing Saccharomyces cerevisiae

Biotechnology for Biofuels and Bioproducts, 2023
Rapid and effective consumption of d-xylose by Saccharomyces cerevisiae is essential for cost-efficient cellulosic bioethanol production. Hence, heterologous d-xylose metabolic pathways have been introduced into S. cerevisiae.

Minimize the Xylitol Production in Saccharomyces cerevisiae by Balancing the Xylose Redox Metabolic Pathway

Frontiers in Bioengineering and Biotechnology, 2021
Xylose is the second most abundant sugar in lignocellulose, but it cannot be used as carbon source by budding yeast Saccharomyces cerevisiae. Rational promoter elements engineering approaches were taken for efficient xylose fermentation in budding yeast.
