Biotechnologie environnementale et chimiométrie appliquées à la valorisation de la biodiversité
The authentication of locust bean and guar powder gums requires usually the use of sophisticated and time-consuming analytical techniques. There is a need for fast and simple analytical techniques for the objective of a quality control methodology. Commercial...
The control of varietal origin is an important issue to insure the authenticity of olive oils. In this study, extra virgin olive oils from five French cultivars were discriminated by applying partial least square discriminant analysis (PLS1-DA) to their...

European Journal of Pharmaceutical Sciences Available online 23 February 2018 The impact of γ-irradiation on polymers in multilayer films was studied by means of the study of the diffusion and release (spontaneous migration of the molecules from the container...
The polyketide, 6-pentyl-alpha-pyrone (6-PP), has a characteristic coconut aroma and is produced by many Trichoderma species. In this study, we screened formerly isolated Trichoderma strains for 6-PP production grown using solid-state fermentation (SSF)....
Plug flow bioreactor (PFB) used in solid state fermentation gives the possibility to have semicontinuous culture. However, it is complicated to follow a single particle during its residence inside the bioreactor and to therefore study precisely the culture...
Production of second-generation bioethanol uses lignocellulose from agricultural by-products such as sugarcane bagasse (SCB). A lignocellulose pre-treatment is required to degrade lignin, ensuring further efficient saccharification. Two experimental designs...
L’information sous toutes ses formes se situe au cœur de la démarche d’intelligence économique. Elle est aussi un vecteur puissant d’innovation et, plus que jamais, des rapports de forces économiques et sociétaux. L'intelligence économique du futur 2...
Thèse présentée par Astrid Maléchaux Il est important d’assurer l’authenticité et la traçabilité des produits alimentaires pour faire face aux préoccupations des consommateurs et aux pertes économiques engendrée par les cas de fraude. Or les huiles d’olive,...
