Developing structure-oriented models for enzymatic hydrolysis of lignocellulosic biomass

With the unsustainable use of fossil fuels increasing strains on human institutions and ecosystems, the development of a renewable energy alternative is of paramount importance. Second generation biorefineries, based on the production of fuels and chemical ...

Equilibrium and non-equilibrium furanose selection in the ribose isomerisation network

Paolo De Los Rios, Shiling Liang, Francesco Piazza, Daniel Maria Busiello

The exclusive presence of beta -D-ribofuranose in nucleic acids is still a conundrum in prebiotic chemistry, given that pyranose species are substantially more stable at equilibrium. However, a precise characterisation of the relative furanose/pyranose fra ...

Sustainable green processing of grape pomace for the production of value-added products: An overview

Edgard Gnansounou

In recent years, the recovery of valuable compounds from food waste like grape pomace is an emerging issue in the food sector. Grape pomace or marc can be considered as an important solid waste that is produced from the wine industries after the pressing a ...

Stabilization strategies in biomass depolymerization using chemical functionalization

Jeremy Luterbacher, Ydna Marie Questell-Santiago

A central feature of most lignocellulosic-biomass-valorization strategies is the depolymerization of all its three major constituents: cellulose and hemicellulose to simple sugars, and lignin to phenolic monomers. However, reactive intermediates, generally ...

Multiple nest entrances alter foraging and information transfer in ants

Bertrand Eric Collignon

The ecological success of ants relies on their ability to discover and collectively exploit available resources. In this process, the nest entrances are key locations at which foragers transfer food and information about the surrounding environment. We ass ...

Carbohydrate Self-Assembly at Surfaces: STM Imaging of Sucrose Conformation and Ordering on Cu(100)

Klaus Kern, Stephan Rauschenbach, Sabine Abb

Saccharides are ubiquitous biomolecules, but little is known about their interaction with, and assembly at, surfaces. By combining preparative mass spectrometry with scanning tunneling microscopy, we have been able to address the conformation and self-asse ...

Molecular Imaging of Biopolymers Enabled by Electrospray-Ion Beam Deposition

Sabine Abb

Biomolecular functional complexes often serve as inspiration for the development of artificial molecular nanostructures. The functionality of the biomolecular structures is based on complex and adaptable binding motifs that have evolved over billions of ye ...

A mild biomass pretreatment using gamma-valerolactone for concentrated sugar production

Jeremy Luterbacher, Ydna Marie Questell-Santiago, Li Shuai

Here we report that gamma-valerolactone (GVL), a biomass-derived solvent, can be used to facilitate the mild pretreatment of lignocellulosic biomass. An 80% GVL, 20% water solvent system was used to pretreat hardwood at the mild temperature of 120 degrees ...

Dissecting the Effects of Concentrated Carbohydrate Solutions on Protein Diffusion, Hydration, and Internal Dynamics

Matteo Dal Peraro, Enrico Spiga, Luciano Andres Abriata, Francesco Piazza

We present herein a thorough description of the effects of high glucose concentrations on the diffusion, hydration and internal dynamics of ubiquitin, as predicted from extensive molecular dynamics simulations on several systems described at fully atomisti ...

Kinetic models in industrial biotechnology - Improving cell factory performance

Vassily Hatzimanikatis, Jens Nielsen

An increasing number of industrial bioprocesses capitalize on living cells by using them as cell factories that convert sugars into chemicals. These processes range from the production of bulk chemicals in yeasts and bacteria to the synthesis of therapeuti ...

Bioethanol production from oil palm empty fruit bunches : a comparison among different pretreatment options

Simone Chiesa

Face to the increasing demand for energy, the declining availability of fossil fuels and the periodical tensions in the geopolitical context of oil-producing countries have raised serious concerns in the governments worldwide as well as in the public opini ...

Polysulfones as new organic catalysts : mechanism and development of new strategies for polyol selective semi-protection

Dean Markovic

Even unsubstituted butadiene adds to sulfur dioxide in the hetero-Diels-Alder mode more rapidly than in the chelotropic mode. The sultine can be observed in equilibrium with the diene and the sulfur dioxide only at low temperature and in the presence of CF ...
