Establishing Lignin Structure-Upgradeability Relationships Using Quantitative 1H-13C Heteronuclear Single Quantum Coherence Nuclear Magnetic Resonance (HSQC-NMR) Spectroscopy

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

Lignin depolymerization could provide an attractive renewable aromatic feedstock for the chemical industry. Past studies have suggested that lignin structural features such as ether content are correlated to lignin’s upgradeability. An obstacle to the deve ...

Highly Selective Oxidation and Depolymerization of α,γ-Diol Protected Lignin

Jeremy Luterbacher, Jean Thierry C Behaghel de Bueren, Wu Lan

Lignin oxidation offers a potential sustainable pathway to oxygenated aromatic molecules. However, current methods that use real lignin tend to have low selectivity and a yield that is limited by lignin degradation during its extraction. We developed stoic ...

Corncob Biorefinery for Platform Chemicals and Lignin Coproduction: Metal Chlorides as Catalysts

Wu Lan

A facile approach to a corncob biorefinery, focusing on both carbohydrate valorization and lignin stabilization, was proposed to coproduce platform chemicals (glucose, xylose, arabinose, and furfural) and lignin. Different metal chloride prehydrolyses of c ...

Enzymes for second generation biofuels: recent developments and future perspectives

Edgard Gnansounou, Binod Parameswaran

Even though the search for alternative fuels from lignocellulosic biomass started a few decades ago, still it is relatively immature mainly because of few challenges which are yet to be solved for making the process commercially viable. The main challenge ...

An “ideal lignin” facilitates full biomass utilization

Jeremy Luterbacher, Li Shuai, Yuan Li

Lignin, a major component of lignocellulosic biomass, is crucial to plant growth and development but is a major impediment to efficient biomass utilization in various processes. Valorizing lignin is increasingly realized as being essential. However, rapid ...

Single-step conversion of lignin monomers to phenol: Bridging the gap between lignin and high-value chemicals

Paul Joseph Dyson, Ning Yan

Transformation of lignin into high-value chemicals is hampered by the complexity of monomers obtained from lignin depolymerization. Here we report a strategy, composed of hydro-demethoxylation and de-alkylation reactions, that is able to chemically converg ...

Protection Group Effects During α,γ-Diol Lignin Stabilization Promote High-Selectivity Monomer Production

Jeremy Luterbacher, Christopher Marc Hunston, Masoud Talebi Amiri, Wu Lan

Protection groups were introduced during biomass pretreatment to stabilize lignin's α,γ-diol group during its extraction and prevent its condensation. Acetaldehyde and propionaldehyde stabilized the α,γ-diol without any aromatic ring alkylation, which sign ...

Carbohydrate stabilization extends the kinetic limits of chemical polysaccharide depolymerization

Jeremy Luterbacher, Masoud Talebi Amiri, Ydna Marie Questell-Santiago, Raquel Zambrano Varela

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 ...

All natural cork composites with suberin-based polyester and lignocellulosic residue

Véronique Michaud, Hugo De Oliveira

Suberin is an aromatic-aliphatic cross-linked polyester structure which constitutes cell wall structures of cork. It is particularly interesting for its use of monomeric compounds towards renewable bio-based polymers. In this study, the extraction of suber ...

Formaldehyde stabilization facilitates lignin monomer production during biomass depolymerization

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

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 ...
