Dihydroxyacetone production via heterogeneous biotransformations of crude glycerol
(Elsevier Science, 2021-11)
In this work, several immobilization strategies for Gluconobacter oxydans NBRC 14819 (Gox) were tested in the bioconversion of crude glycerol to dihydroxyacetone (DHA). Agar, agarose and polyacrylamide were evaluated as ...
Dihydroxyacetone Induced Autophagy in African Trypanosomes
(Landes Bioscience (Autophagy), 2013)
Identification and biochemical characterization of an ATP-dependent dihydroxyacetone kinase from Trypanosoma cruzi
(Academic Press Inc Elsevier Science, 2021-12)
Dihydroxyacetone (DHA) can be used as an energy source by many cell types; however, it is toxic at high concentrations. The enzyme dihydroxyacetone kinase (DAK) has shown to be involved in DHA detoxification and osmoregulation. ...
An alternative approach for quantification of glyceraldehyde and dihydroxyacetone as trimethylsilyl derivatives by GC-FID
(Elsevier, 2020-01)
A method for quantification of glyceraldehyde (GA), dihydroxyacetone (DHA) and glycerol (GLY) by gas chromatography coupled to a flame ionization detector (GC-FID) involving one-step derivatization into trimethylsilyl ...
Synthesis of ethyl lactate from triose sugars on Sn/Al2O3 catalysts
(Elsevier Science, 2016-05)
Sn-promoted alumina catalysts with different Sn loadings (1-8 wt.%) were prepared by impregnation and characterized by N2 physisorption, X-ray diffraction, UV-vis-DRS, FTIR of pyridine and TPD of NH3. Surface Sn species ...
Oxidation of glycerol in the presence of hydrogen peroxide and iron in model solutions and wine. Potential effects on wine color
(American Chemical Society, 2007)
Kinetic and mechanistic study of triose sugar conversion on Lewis and Brønsted acid solids
(Elsevier B.V., 2017-12)
The effect of catalyst acid site nature on the reaction kinetics of the liquid-phase conversion of dihy-droxyacetone with ethanol was investigated using Brønsted and Lewis acid solids. The reaction proceedsthrough a complex ...
Tuning product selectivity in the catalytic oxidation of glycerol by employing metal-ZSM-11 materials
(Royal Society of Chemistry, 2020-02-21)
Copper and chromium supported on ZSM-11 (MEL-type structure) microporous zeolites were investigated as catalysts for glycerol oxidation towards dihydroxyacetone and lactic acid. ZSM-11 was synthesized by hydrothermal ...
Harnessing glycerol from biodiesel fuel production to obtain valuable industrial compounds
(Instituto de Histología y Embriología, 2009-10)
Glycerol (Gro) has many appliances in the cosmetic, food, and pharmaceutical industries. However, Gro has become an inexpensive carbon source due to its generation as inevitable by-product of the biodiesel production, a ...
Kinetic study of the ethyl lactate synthesis from triose sugars on Sn/Al 2 O 3 catalysts
(Elsevier Science, 2017-07)
The reaction kinetics of the liquid-phase synthesis of ethyl lactate from dihydroxyacetone and ethanol was studied on Sn-promoted alumina catalysts. Yields of ≈70% were obtained at 353K after 7 hours of reaction. The effect ...
