Valorization of rapeseed meal by solid state fermentation for an application in animal nutrition
2017
Solid state fermentation (SSF) is a biotechnological process particularly well adapted to the treatment of vegetable biomass. This technology adjustable to industrial scale, is adapted to current challenges in animal nutrition by developing fermented products in order to improve the quality of raw materials from a nutritional and functional point of view. The work presented in this thesis considers these issues using rapeseed meal from the oil crushing industry.A first screening study highlighted several fungal strains based on their growth performance and protein enrichment (total and digestible) of the substrate. Levels similar to those of soybean meal, the main protein source in animal n…

Risultati preliminari del monitoraggio di lepidotteri diurni in un sito di interesse comunitario per differenti scopi applicativi
2010
Durante il XX secolo e specialmente negli ultimi 50 anni è stato riportato un declino nel numero specie di lepidotteri diurni presenti in Europa, ed ad una modificazione delle comunità delle farfalle. Tale decremento è stato attributo a diversi fattori: frammentazione e la scomparsa degli habitat e l'intensificazione dell'agricoltura e delle pratiche ad essa connesse. L'introduzione di nuovi prodotti in agricoltura, quali ad esempio le piante geneticamente modificate o i prodotti a base di virus entomopatogeni hanno posto ancor più l'accento sulla necessità di monitorare i lepidotteri non target (principalmente i diurni) sia come data set iniziale sia per i piani di post monitoring. A tal f…

Gene flow from oilseed rape to weedy species
2003
The assessment of the likelihood of transgene spread from cultivated species to their wild relatives is relevant for oilseed rape (Brassica napus, AACC, 2n=38) as it is partially allogamous and pre...
Conséquences écologiques et évolutives du flux de gènes entre Brassica napus transgénique et ses apparentés sauvages
2010
In the framework of commercial release for transgenic crops with novel traits, consequences of gene flow and introgression are still one main concern. I explored the ecological and evolutionary consequences of gene flow between oilseed rape (Brassica napus) and its wild relatives, brown mustard (B. juncea) and wild radish (Raphanus raphanistrum), through several experiments carried out in greenhouse, common garden and field in Beijing and Dijon. First, I revised a comprehensive review of the literature about gene flow and its effect on plant fitness in the Brassiceae. Second, I investigated the effects on gene flow of seed size of hybrids between Bt-transgenic oilseed rape and mustard. Smal…
