The use of flow cytometry to assess Rhodosporidium toruloides NCYC 921 performance for lipid production using Miscanthus sp. hydrolysates

open access: yesBiotechnology Reports, 2021
The yeast Rhodosporidium toruloides NCYC 921 was used for lipid production, using Miscanthus biomass hydrolysate as carbon source. The hydrolysate was obtained by enzymatic hydrolysis of Miscanthus biomass (at high solids loading) previously subjected to

Thermodynamic and kinetic modeling of the protection of mammalian cells against ethanol‐induced damage by extracts of Jatropha curcas (Euphorbiaceae)

open access: yesEngineering Reports, Volume 1, Issue 5, December 2019., 2019
Jatropha curcas extracts protect mammalian cells against damage by ethanol. A thermodynamic modeling of protection based on extract concentrations is presented. Optimization of protection could be done using the proposed model. The medicinal plant Jatropha curcas exerts beneficial effects against ethanol toxicity in humans.

Non‐Hydrothermal Synthesis of MCM‐41‐Type Catalysts Modified With Zirconia and Tungsten Oxide for the Esterification of Levulinic Acid With Ethanol

open access: yesChemistrySelect, Volume 11, Issue 8, 25 February 2026.
Ordered mesoporous silica MCM‐41, synthesized through a simple and rapid non‐hydrothermal method, was functionalized with ZrO2 and WO3 for catalytic application in the esterification of levulinic acid with ethanol. The incorporation of these oxides yielded active and stable acidic heterogeneous catalysts that maintained their catalytic activity for 180

About the Influence of Doping Approach on the Alkali Metal Catalyzed Slow Pyrolysis of Xylan

open access: yesJournal of Chemistry, Volume 2019, Issue 1, 2019., 2019
In this study, we highlighted how the catalytic effect of alkali metals on xylan pyrolysis is strongly affected by the adopted doping approach. Thermogravimetric and pyrolysis tests, up to 973 K and at a heating rate of 7 K/min, were conducted on a set of potassium‐ or sodium‐doped xylan samples containing controlled amounts of KCl or NaCl introduced ...
