We hydrogenated biomass-derived 5-hydroxymethylfurfural (HMF) in aqueous medium a reaction catalyzed by palladium nanoparticles (Pd) on carbonaceous materials with different morphology and hydrophobic degree. The Pd catalysts were prepared dipping the material into Pd0 micro-emulsion. catalyst support affected catalytic HMF hydrogenation. By using micrometric active carbon (AC) combined cup-sta...

The preparation of compounds interest from biomass-derived 5-hydroxymethylfurfural (HMF) has attracted considerable attention. One such compound is 2,5-diformylfuran (DFF), obtained through oxidation the hydroxyl group HMF. Herein, we describe for first time whole-cell HMF to DFF by Fusarium culmorum EAN 51. Although chemocatalytic transformation into been widely studied, biocatalytic processes...

The industrial yeast Saccharomyces cerevisiae is a traditional ethanologenic agent and a promising biocatalyst for advanced biofuels production using lignocellulose materials. Here we present the genomic background of type strain NRRL Y-12632 and its transcriptomic response to 5-hydroxymethyl-2-furaldehyde (HMF), a commonly encountered toxic compound liberated from lignocellulosic-biomass pretr...

Although concentrated sulfuric acid saccharification is not a novel method for breaking down lignocellulosic biomass, the process by which saccharification affects biomass decomposition, sugar recovery, and by-product generation is not well studied. The present study employed Taguchi experimental design to study the effects of seven parameters on corn stover concentrated sulfuric acid saccharif...

5-Hydroxymethylfurfural (HMF) and furfuryl alcohol (FFA) are present in numerous foodstuffs at high levels. FFA is also used for the production of polymers. Both compounds had demonstrated some evidence of carcinogenic activity in 2-year bioassays. We tested these compounds and four congeners for mutagenicity in Salmonella typhimurium TA100 and TA100-derived strains expressing human or rodent s...

Efficient and selective conversion of renewable feedstocks to essential chemicals fuels applying green sustainable catalytic processes is central importance attracts scientific interest. Among different biomass-based feedstocks, 5-hydroxymethylfurfural (HMF) represents valuable platform compound widely used for the synthesis chemicals, fuels, polymers. Here we report cobalt nanoparticles cataly...

Degradation products from sugars and lignin are commonly generated as byproducts during pretreatment of biomass being processed for production renewable fuels chemicals. Many the degradation act microbial inhibitors, including furanic phenolic compounds acetate, which is solubilized hemicellulose. We previously identified a group fungi, Coniochaeta species, that intrinsically tolerant to capabl...

Herein, twoN-substituted coumaryl hydroxylamines (compounds 1a and 1b) with long aliphatic chains were prepared in 8 steps with a novel synthetic protocol. They served as derivatization agents for aldehydes by the formation of nitrones under mild conditions, which can be readily analysed by LC-MS with good chromatographic performance, excellent fluorescent response, and high ionization strength...
