Carboxylic acid isomer-directed synthesis of CdS nanocluster isomers

Selective synthesis of nanocluster (NC) isomers with tailored structures holds significant importance for enhancing their applications. Here, we develop an effective strategy for the selective synthesis of CdS NC isomers through the judicious choice of a p ...

The capture technology matters: Composition of municipal wastewater solids drives complexity of microbial community structure and volatile fatty acid profile during anaerobic fermentation

Pierre Rossi, Arnaud Michel Gelb

The production of volatile fatty acids (VFAs) represents a relevant option to valorize municipal wastewater (MWW). In this context, different capture technologies can be used to recover organic carbon from wastewater in form of solids, while pre-treatment ...

A heterogeneous microbial consortium producing short-chain fatty acids from lignocellulose

Jeremy Luterbacher

Microbial consortia are a promising alternative to monocultures of genetically modified microorganisms for complex biotransformations. We developed a versatile consortium-based strategy for the direct conversion of lignocellulose to short-chain fatty acids ...

Catalytic valorization of the acetate fraction of biomass to aromatics and its integration into the carboxylate platform

Jeremy Luterbacher, Masoud Talebi Amiri, Ydna Marie Questell-Santiago, Benjamin Pierre Le Monnier, Jher Hau Yeap, Bartosz Rozmyslowicz, Ahmed Mohamed Ibrahim Elkhaiary

In many plant species, the acetate fraction is the fourth most prominent fraction by weight after cellulose, hemicellulose and lignin, and can be easily extracted as a single stable molecule, acetic acid, at high yields. Despite this, upgrading the acetate ...

Impact of iron reduction on the metabolism of Clostridium acetobutylicum

Vassily Hatzimanikatis, Rizlan Bernier-Latmani, Karin Lederballe Meibom, Cornelia List, Zhaleh Hosseini

Iron is essential for most living organisms. In addition, its biogeochemical cycling influences important processes in the geosphere (e.g., the mobilization or immobilization of trace elements and contaminants). The reduction of Fe(III) to Fe(II) can be ca ...

Catalytic Upgrading of Biomass-Derived Carboxylic Acids to Fuels and Chemicals

Jher Hau Yeap

Our reliance on fossil fuels, which is unsustainable due to dwindling reserves, has led to various environmental issues. Lignocellulosic biomass could serve as a renewable source of carbon and energy for the production of fuels and chemicals. While several ...

Selectivity control during the single-step conversion of aliphatic carboxylic acids to linear olefins

Jeremy Luterbacher, Jher Hau Yeap, Florent Emmanuel Héroguel, Bartosz Rozmyslowicz

We have studied the single-step catalytic conversion of biomass-derived aliphatic carboxylic acids to linear olefins via tandem hydrogenation/dehydration reactions. Hexanoic acid was converted to a mixture of hexenes (92.0% selectivity) over silica–alumina ...

Probing cardiac metabolism by hyperpolarized 13C MR using an exclusively endogenous substrate mixture and photo-induced nonpersistent radicals

Rolf Gruetter, Andrea Capozzi, Arnaud Comment, Josefina Adriana Maria Bastiaansen, Hikari Ananda Infinity Yoshihara

Purpose To probe the cardiac metabolism of carbohydrates and short chain fatty acids simultaneously in vivo following the injection of a hyperpolarized 13C-labeled substrate mixture prepared using photo-induced nonpersistent radicals. Methods Droplets of m ...

Variability in DPA and calcium content in the spores of Clostridium species

Rizlan Bernier-Latmani, Barbora Bártová, Imrich Barak, Zuzana Chromiková, Cornelia List, Jan Jamroskovic

Spores of a number of clostridia' species, and their resistance to thermal treatment is a major concern for the food industry. Spore resistance to wet heat is related to the level of spore hydration, which is inversely correlated with the content of calciu ...

Determination of the structure of the O-antigen and the lipid A from the entomopathogenic bacterium Pseudomonas entomophila lipopolysaccharide along with its immunological properties

Bruno Lemaitre

The structure and the immunology of the lipopolysaccharide (LPS) of Pseudomonas entomophila, an entomopathogenic bacterium isolated from the fruit fly Drosophila melanogaster, was characterized. The O-antigen portion was established and resulted to be buil ...
