Production of Laccase by Recombinant Yarrowia lipolytica from Molasses: Bioprocess Development Using Statistical Modeling and Increase Productivity in Shake-Flask and Bioreactor Cultures

Farshad Darvishi, Marzieh Moradi, Catherine Madzak, Claude Jolivalt

Laccases are used in numerous applications, from green degradation of various xenobiotic compounds, waste detoxification, textile dye bleaching, and delignification of lignocellulose materials to biofuel production. In this study, the recombinant Yarrowia lipolytica YL4 strain carrying the white-…

Building of an immunosensor : how can the composition and structure of the thiol attachment layer affect the immunosensor efficiency ?

Elisabeth Briand, Michèle Salmain, Jean-Marie Herry, Hubert Perrot, Chantal Compere, Claire-Marie Pradier

Immunosensors, based on the immobilsation of model rabbit antibodies on a mixed self assembled monolyaers and Protein A as a linking agent on gold transducers, were elaborated and characterised at each step by Modulated polarisation- Infrared Spectroscopy (PM-IRRAS) and punctually by Atomic Force…

Silk Polymers and Nanoparticles: A Powerful Combination for the Design of Versatile Biomaterials

Cristina Belda Marín, Vincent Fitzpatrick, David Kaplan, Jessem Landoulsi, Erwann Guénin, Christophe Egles

Silk fibroin (SF) is a natural protein largely used in the textile industry but also in biomedicine, catalysis, and other materials applications. SF is biocompatible, biodegradable, and possesses high tensile strength. Moreover, it is a versatile compound that can be formed into different materials…

Intermittent dynamics of bubble dissolution due to interfacial growth of fat crystals

Irma Liascukiene, Gabriel Amselem, Jessem Landoulsi, Deniz Gunes, Charles Baroud

Foams are inherently unstable objects, that age and disappear over time. The main cause of foam aging is Ostwald ripening: smaller air bubbles within the foam empty their gas content into larger ones. One strategy to counter Ostwald ripening consists in creating armored bubbles, where solid…

Au-Ru/TiO2 prepared by deposition-precipitation with urea: Relevant synthesis parameters to obtain bimetallic particles

Lina Calzada, Catherine Louis, Chang Wan Han, Volkan Ortalan, Rodolfo Zanella

Although Au and Ru are not miscible in the bulk, the paper focusses on the attempts to prepare bimetallic Au-Ru/TiO2 catalysts by deposition-precipitation with urea (co-DPU and sequential DPU, Au then Ru and vice versa). Gold was found already reduced after the preparations of co-DPU and Ru then Au…

Partial oxidation of methane over bifunctional catalyst I. In situ formation of Ni0/La2O3 during temperature programmed POM reaction over LaNiO3 perovskite

Tri Huu Nguyen, Agata Łamacz, Patricia Beaunier, Sylwia Czajkowska, Marian Domański, Andrzej Krztoń, Tiep van Le, Gérald Djéga-Mariadassou

The transformation of perovskite to an oxide-supported metal during reaction of partial oxidation of methane (POM) has been very often cited in literature as the “reduction” of the perovskite, without any detailed mechanism. In this work, the in situ transformation of initial LaNiO3 perovskite to…

Silica-Supported Au-Ag Catalysts for the Selective Hydrogenation of Butadiene

Nazila Masoud, Laurent Delannoy, Christophe Calers, Jean-Jacques Gallet, Fabrice Bournel, Krijn P. de Jong, Catherine Louis, Petra E. de Jongh

Gold and silver are miscible over the entire composition range, and form an attractive combination for fundamental studies on bimetallic catalysts. Au–Ag catalysts have shown synergistic effects for different oxidation and liquid-phase hydrogenation reactions, but have rarely been studied for gas-…

Tuning the shape and size of hybrid gold nanoparticles by porphyrins using seed-mediated synthesis

Jolanda Spadavecchia, Sandra Casale, Jessem Landoulsi, Claire-Marie Pradier

We report the synthesis of hybrid gold nanostructures by means of seed/growth approach, using porphyrin molecules (protoporphyrin IX) in addition to cetyltetraammonium bromide (CTAB) as surfactants and/or shape-modulating agents. The combination of CTAB and porphyrin yields stable complexes that…

Effect of Fe on the activity of Au/FeO x -TiO2 catalysts for CO oxidation

Mpfunzeni Raphulu, Thabang Ntho, Pumeza Gqogqa, John Moma, Lebohang Mokoena, Gary Pattrick, Mike Scurrell, Laurent Delannoy, Catherine Louis

A thorough characterisation of Au/TiO2 and Au/ FeOx-TiO2 catalysts was conducted in order to get a better understanding of the effect of Fe on the Au/TiO2 catalysts and link it to differences observed in their activities for CO oxidation. Several techniques including HRTEM, temperature-programmed…
