Carbohydrate stabilization extends the kinetic limits of chemical polysaccharide depolymerization

Jeremy Luterbacher, Masoud Talebi Amiri, Ydna Marie Questell-Santiago

Polysaccharide depolymerization is an essential step for valorizing lignocellulosic biomass. In inexpensive systems such as pure water or dilute acid mixtures, carbohydrate monomer degradation rates exceed hemicellulose—and especially cellulose—depolymeriz ...

Bioconversion of pentose sugars to value added chemicals and fuels: Recent trends, challenges and possibilities

Edgard Gnansounou

Most of the crop plants contain about 30% of hemicelluloses comprising D-xylose and D-arabinose. One of the major limitation for the use of pentose sugars is that high purity grade D-xylose and D-arabinose are yet to be produced as commodity chemicals. Res ...

Consolidated bioprocessing of lignocellulosic biomass to lactic acid by a synthetic fungal-bacterial consortium

Jeremy Luterbacher

Consolidated bioprocessing (CBP) of lignocellulosic feedstocks to platform chemicals requires complex metabolic processes, which are commonly executed by single genetically engineered microorganisms. Alternatively, synthetic consortia can be employed to co ...

Cellulose Nanocrystals with Tethered Polymer Chains: Chemically Patchy versus Uniform Decoration

Harm-Anton Klok, Alke Fink

The site-specific surface modification of colloidal substrates, yielding "patchy" nanoparticles, is a rapidly expanding area of research as a result of the new complex structural hierarchies that are becoming accessible to chemists and materials scientists ...

Comparison of liquid hot water (LHW) and high boiling alcohol/water (HBAW) pretreatments for improving enzymatic saccharification of cellulose in bamboo

Li Chen, Li Shuai

Liquid hot water (LHW) and high-boiling point alcohol/water (HBAW) pretreatments were compared to improve enzymatic saccharification of cellulose in moso bamboo. When pretreatments were conducted at 200 degrees C for 40 min, HBAW (20% (v/v) 1,4- butanediol ...

A novel surfactant assisted transition metal pretreatment of chili post harvest residue for the production of bioethanol

Edgard Gnansounou

Increase in consumption as well as depletion of fossil fuels and environmental concerns about the consequences of burning fossil fuels leads to search for alternative renewable fuels. Lignocellulosic biomasses are plenteous in nature and are rich in cellul ...

Direct Conversion of Mono- and Polysaccharides into 5-Hydroxymethylfurfural Using Ionic-Liquid Mixtures

Paul Joseph Dyson, Rosario Scopelliti, Zhaofu Fei, Ning Yan, Sviatlana Siankevich

Platform chemicals are usually derived from petrochemical feedstocks. A sustainable alternative commences with lignocellulosic biomass, a renewable feedstock, but one that is highly challenging to process. Ionic liquids (ILs) are able to solubilize biomass ...

Titanium oxide aerogel composites

László Forró, Arnaud Magrez, Endre Horvath

The invention relates to titanium oxide aerogels, in particular to titanium oxide binary or ternary (e.g. titanium oxide-carbon) aerogel monoliths possessing ordered meso- and macroporosity. The porous scaffold can be made with or without addition of binde ...

Formaldehyde stabilization facilitates lignin monomer production during biomass depolymerization

Yiming Li, Jeremy Luterbacher, Li Shuai, Florent Emmanuel Héroguel, Masoud Talebi Amiri, Ydna Marie Questell-Santiago

Practical, high-yield lignin depolymerization methods could greatly increase biorefinery productivity and profitability. However, development of these methods is limited by the presence of interunit carbon-carbon bonds within native lignin, and further by ...
