Aldehyde Electrophilicity and Ring Strain Govern Xylose Acetalization Pathways for Biobased Chemical Production. [PDF]

ChemSusChem
Reaction kinetics and operando heteronuclear single quantum coherence nuclear magnetic resonance studies revealed the reaction pathway of xylose acetalization with different aldehydes. Product distribution and yields were significantly influenced by aldehyde electrophilicity and the orientation of xylose hydroxyl groups.

Sustainable and cost‐effective process design for energy‐self‐sufficient ethyl lactate production from sugar mill feedstocks: a techno‐economic approach

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Bio‐based ethyl lactate (EL) can replace several fossil‐derived products owing to its low toxicity, high solvent functionality, and environmental advantages. This study assesses the techno‐economic viability and greenhouse gas (GHG) reduction potential of producing EL from sugarcane A‐molasses and lignocelluloses in an energy self‐sufficient ...

Effective acetalization of furfural catalyzed by Fe‐ and Co‐oxalates: impact of alcohols structure on products composition

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Fe‐, Co‐, and FeCo‐oxalates supported on silica gel (5 wt% metal load) were synthesized, characterized, and tested for the first time in solvent‐free furfural (FF) acetalization with C1–C8 alcohols at 70–170 °C under both conventional and microwave (MW)‐assisted conditions. The interaction of FF with linear C1–C4 alcohols yielded pincer‐shaped

Integrated bioconversion of starchy and hemicellulosic fractions of macauba oil presscake into ethanol by nonconventional yeasts

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Co‐fermentation of hexoses and pentoses from plant biomass to ethanol is a strategy to increase ethanol production from lignocellulosic materials and add value to residues from agroindustrial chains. The macauba (Acrocomia aculeata) is an oleaginous palm‐tree species considered to contribute to development in some regions of Brazil.

Metabolic Engineering of Saccharomyces cerevisiae for Enhanced Carotenoid Production From Xylose-Glucose Mixtures

Frontiers in Bioengineering and Biotechnology, 2020
Co-utilization of xylose and glucose from lignocellulosic biomass is an economically feasible bioprocess for chemical production. Many strategies have been implemented for efficiently assimilating xylose which is one of the predominant sugars of ...

Raw citrus by‐product valorization: unlocking the potential of biotransformation by Talaromyces amestolkiae to obtain cellulolytic enzymes and natural colorants

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Agro‐industrial by‐products can be used as valuable nutrient sources for the sustainable production of high‐value‐added compounds. The goal of this study was utilize raw citrus industrial by‐product (RCB) as a carbon source for the simultaneous production of red colorants and enzymes by the filamentous fungus Talaromyces amestolkiae under lab ...

Psilocybin Production With Genetically Modified Aspergillus nidulans Under Pressurized Conditions

Biotechnology and Bioengineering, EarlyView.
Shake flask cultures of psilocybin‐producing A. nidulans were investigated with respect to nitrogen source, rheology, power input, and oxygen availability, and subsequently scaled to a stirred tank reactor scale based on specific power input to develop and optimize a pressurized bioprocess.

Urinary xylose excretion in steatorrhoea [PDF]

Gut, 1962
The urinary xylose excretion is low in patients with untreated idiopathic steatorrhoea but subsequent improvement in excretion was noted after treatment in six out of nine patients. This did not coincide with histological improvement. With Crohn's disease low values were found when the jejunum but not the ileum was involved.

Untargeted Metabolomics Reveals Seasonal and Tissue‐Specific Metabolic Shifts in Holothuria cinerascens

Chemistry &Biodiversity, EarlyView.
Untargeted metabolic profiling of three body tissues from Holothuria cinerascens in South Africa using 1H‐NMR and UPLC–QTOF–MS revealed distinct tissue‐specific and seasonal metabolic variations, with the body wall and gut/mesentery exhibiting high metabolite diversity.

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.
