Laccase production from sucrose by recombinant Yarrowia lipolytica and its application to decolorization of environmental pollutant dyes

Farshad Darvishi, Marzieh Moradi, Claude Jolivalt, Catherine Madzak

Laccases are used in decolorization and biodegradation of synthetic dyes, bioremediation of industrial waste-waters and delignification of lignocellulosic compounds. The aims of the present study were the optimization of a recombinant laccase production in Yarrowia lipolytica yeast using sucrose as…

Curie composite nanoparticles for advanced manufacturing and catalysis, NPs Curie Composites pour la fabrication avancée et la catalyse

Naoures Hmili

This thesis investigates the design and functionalization of magnetic nanoparticles (MNPs) in the fields of resin cross-linking and catalysis by magnetic hyperthermia. Mn and Zn ferrite nanoparticles were synthesized with adjustable size and composition, allowing precise control of magnetic…, Cette thèse porte sur la conception et la fonctionnalisation de nanoparticules magnétiques (MNP) pour des applications dans les domaines de la réticulation des résines et de la catalyse par hyperthermie magnétique. Des nanoparticules de ferrite de Mn et de Zn ont été synthétisées avec une taille et…

Polypyrrole nanostructures modified with mono- and bimetallic nanoparticles for photocatalytic H2 generation

Xiaojiao Yuan, Diana Dragoe, Patricia Beaunier, Daniel Bahena Uribe, Laurence Ramos, Maria Guadalupe Méndez-Medrano, Hynd Remita

Conjugated polymer polypyrrole nanostructures modified with bimetallic (Pt–Ni) nanoparticles are very active for hydrogen generation and a synergetic effect is obtained by alloying Pt with Ni.

A comparative study of alanine adsorption and condensation to peptides in two clay minerals

Fabrícia de Castro Silva, Luciano Clécio Brandão Lima, Edson Silva-Filho, Maria Gardennia Fonseca, Jean-François Lambert, Maguy Jaber

The polycondensation of amino acids to oligopeptides is an important step in the origins of life, and known to be effective on several mineral surfaces. The data available on clay mineral surfaces are heterogeneous and sometimes contradictory, however. The objective of the present work is to…

On the origin of the changes in color of Ag/Al2O3 catalysts during storage

Tesnim Chaieb, Dalil Brouri, Sandra Casale, Jean-Marc Krafft, Tiago da Silva, Cyril Thomas, Laurent Delannoy, Catherine Louis

Despite the large number of catalytic studies involving Ag/Al2O3 catalysts, especially in deNOx reactions, the phenomenon of ageing observed during catalysts storage after preparation by impregnation followed by a calcination treatment, has not been reported earlier and rises questions. The present…

Synthesis and characterization of Ag-Protoporphyrin nano structures using mixed co-polymer method

Ramesh Perumal, Sandra Casale, Luca de Stefano, Jolanda Spadavecchia

In this paper, we report the synthesis of hybrid silver nanostructures (AgNPs) based on an effective mixing of polyols with Polyvinylpyrrolidone (PVP) and Porphyrin molecules, in particular Protoporphyrin IX (PP). The combination of PVP and PP, which act as co-directing agents and favour the…

Revealing the Interplay between Adsorbed Molecular Layers and Gold Nanoparticles by Linear and Nonlinear Optical Properties

Laetitia Dalstein, Maroua Ben Haddada, Grégory Barbillon, Christophe Humbert, Abderrahmane Tadjeddine, Souhir Boujday, Bertrand Busson

Gold nanoparticles (AuNPs) chemically grafted on substrates are widely used as sensors due to their plasmonic properties. The efficiency and robustness of such sensors strongly depend on the molecular sublayer structure, which influences the distribution of AuNPs, and therefore the plasmonic…

Ordered Nanostructures on a Hydroxylated Aluminum Surface through the Self-Assembly of Fatty Acids.

Irma Liascukiene, Nesrine Aissaoui, Svajus J. Asadauskas, Jessem Landoulsi, Jean-François Lambert

We investigate the mechanism of self-assembly of fatty acids (FA) and methyl oleate on an Al oxy-hydroxide surface with a view to deciphering the role and nature of interfacial processes (adsorption, chemical binding, molecular organization, etc.). For this purpose, we focus on parameters related…

Bioactive peptides grafted silicone dressings: A simple and specific method

Coline Pinese, Said Jebors, Pierre-Emmanuel Stoebner, Vincent Humblot, Pascal Verdié, Léa Causse, Xavier Garric, Hubert Taillades, Jean Martinez, Ahmad Mehdi, Gilles Subra

The need for bioactive dressings increases with the population aging and the prevalence of chronic diseases. In contrast, there are very few dressings on the market which are designed to display a chosen bioactivity. In this context, we investigated the surface-functionalization of silicone wound…
