The formation of toxic fermentation inhibitors such as furfural and 5-hydroxy-2-methylfurfural (HMF) during acid (pre-)treatment of lignocellulose, calls for the efficient removal of these compounds. Lignocellulosic hydrolysates can be efficiently detoxified biologically with microorganisms that specifically metabolize the fermentation inhibitors while preserving the sugars for subsequent use b...

A novel single phase co-solvent system using tetrahydrofuran (THF) promotes hydrolysis of maple wood to sugars, sugar dehydration, and lignin extraction simultaneously and achieves higher overall yields of the fuel precursors furfural, 5-hydroxymethylfurfural (HMF), and levulinic acid (LA) than previously reported from biomass. In a one-pot reaction, we obtained yields of 86% furfural, 21% HMF,...

The use of alkyl levulinates is growing interest in fuels. Adding n-butyl levulinate (BL) to fuels presents some benefits compared ethyl levulinate. conventional production route BL from the esterification levulinic acid, but latter compound corrosion issues. Alcoholysis fructose by butanol over cation exchange resins (solid catalyst) seems be a better alternative. effect water addition, solven...

5-Hydroxymethylfurfural (HMF) is a biobased platform chemical that can be valorized into spectrum of valuable products. In this report, supported Ir, Ir–Co, Ir–Ni, and Ir–Ru catalysts were investigated for purpose. Only hydrogenation HMF to 2,5-bis-(hydroxymethyl)furan (BHMF) occurred over all catalysts. The effect the second metal (Co, Ni, Ru) on Ir/SiO2 was reflected by kinetic constants bein...

BACKGROUND Pichia stipitis xylose reductase (Ps-XR) has been used to design Saccharomyces cerevisiae strains that are able to ferment xylose. One example is the industrial S. cerevisiae xylose-consuming strain TMB3400, which was constructed by expression of P. stipitis xylose reductase and xylitol dehydrogenase and overexpression of endogenous xylulose kinase in the industrial S. cerevisiae str...

A series of original amphiphiles prepared by Morita–Baylis–Hillman (MBH) coupling biobased furanic aldehydes with hydrophobic alkenes is explored. Structural variations result from the level polarity on substrate, type activated (ester amide), alkyl chain length, and presence an unsaturation. The physicochemical properties such as Krafft point, critical micellar concentration (CMC), hydrophilic...

Electrochemical conversion of biomass-derived 5-hydroxymethyl-furfural (HMF) to 2,5-furandicarboxylic acid (FDCA), the building block bio-based plastics, is an attractive process that leverages renewable electrons and carbon resources. The offers potential increase energy cost efficiency by combining mild reaction conditions with high activity selectivity. This study elucidates mechanism kineti...

Lignocellulosic biomass, a cheap and plentiful resource, could play key role in the production of sustainable chemicals. The simple sugars contained renewable lignocellulosic biomass can be converted into commercially valuable products such as 5-hydroxymethyl furfural (HMF). A platform molecule, HMF transformed numerous chemical with potential applications wide variety industries. Of hexoses su...
