Integrated permeate channel (IPC) flat sheet membranes were examined for use as a reverse membrane bioreactor (rMBR) for lignocellulosic ethanol production. The fermenting organism, Saccharomyces cerevisiae (T0936), a genetically-modified strain with the ability to ferment xylose, was used inside the rMBR. The rMBR was evaluated for simultaneous glucose and xylose utilization as well as in situ...

the purpose of this study was to develop a sensitive and fast microdialysis coupled with high-performance liquid chromatographic (hplc) method for determination of 5-hydroxymethyl-2-furaldehyde (5-hmf) in free-moving rats after i.g. administration of the aqueous extract of crud fructus corni and its processed products of jiuzheng pin (jzp). the concentration of 5-hmf in free-moving rats after i...

Malic acid is a dicarboxylic acid widely used in the food industry, and is also a potential C4 platform chemical. Corncob is a low-cost renewable feedstock from agricultural industry. However, side-reaction products (furfural, 5-hydroxymethylfurfural (HMF), formic acid, and acetic acid) that severely hinder fermentation are formed during corncob pretreatment. The process for producing malic aci...

In alloyed nanoparticles, synergistic electronic and/or geometric effects may enhance the catalytic properties compared to their monometallic counterparts. Herein, we address synthesis of bimetallic Au/Cu nanoparticles with different compositions by wet chemical reduction in ionic liquids. The were successively supported on carbon. liquid could be recycled after synthesis. Annealing carbon-supp...

A lo largo de mi doctorado, me dedicaré a desarrollar catalizadores nanoestructurados basados en materiales mesoporosos, modificados con nanopartículas activas, para su aplicación la obtención 5-hidroximetil furfural (HMF) partir hidratos carbonos simples (hexosas); y posterior hidrogenación del HMF 2,5-dimetil furano (DMF) producto alto valor energético.

The discovery of huge petroleum reserves in the 19th century was a golden opportunity that promoted industrial revolution, by offering wide variety cheap raw materials and reliable source energy. This caused an unprecedented increase commodity production specialty chemicals order to fulfill needs global markets. However, as warming environmental issues has become hazardous worried situation, re...

BACKGROUND A previously discovered mutant of Saccharomyces cerevisiae alcohol dehydrogenase 1 (Adh1p) was shown to enable a unique NADH-dependent reduction of 5-hydroxymethylfurfural (HMF), a well-known inhibitor of yeast fermentation. In the present study, site-directed mutagenesis of both native and mutated ADH1 genes was performed in order to identify the key amino acids involved in this sub...

The heat treatment process usually affects the quality and safety of milk could produce different compounds, including furosine furfurals. To help evaluate effect heating temperatures on furfurals, a method based gas chromatography-mass spectrometry (GC-MS) combined with QuEChERS (quick, easy, cheap, effective, rugged, safe) extraction technology was used to detect four furfural furfural, 2-ace...
