L’acquisition de la représentation du temps nous donne, avec le développement du langage, accès à la narrativité. Ces histoires que nous racontons aux enfants leur permettent d’accéder au monde de la signification. Peu à peu l’enfant s’approprie sa propre histoire en même temps qu’il constitue son identité. Le concept de self narrative (Denett, 1991), matérialisé dans le discours par l’utilisation des pronoms personnels, est un premier produit de cette évolution. Il est donc intéressant de connaître la manière dont se construit ce récit qui deviendra autobiographique à l’adolescence. [less ▲]

Abstract : The design of a new single species biofilm bioreactor has been investigated. Bacillus subtilis S499 has been chosen as a model organism for the production of lipopetides. Nevertheless, considering the surface active properties for this kind of metabolite, processes based on submerged culture in stirred-tank bioreactor involve the use of important amount of antifoam and therefore downstream processes are tedious. In this work, an original process was developed with an experimental setting leading to the suppression of foam formation during the culture. B. subtilis S499 makes a biofilm on a stainless steel structured packing in the top of a bioreactor, nutrient and oxygen supply being carried out by the media recirculation as liquid film on the packing. Lipopeptides secreted by biofilm are accumulated in the liquid phase under the packing and can reach concentrations as high as 800 mg/l. The colonization of the packing by the biofilm has been monitored by X-ray tomography. [less ▲]

Rapeseed meal is one of the main industrial co-products from agriculture in Belgium, with more than 30 000 T produced each year. Beside its agricultural and energetic applications, new paths of valorization are being developed in order to add value to the rapeseed meal, usually by extraction of interesting molecules. In this thesis project, the aimed molecules are hemicelluloses, which are obtained via a global fractionation method that is being developed and optimized, constituting the first part of this project. Indeed, while rapeseed meals are globally already well exploited (mainly for their feed value), rapeseed hemicelluloses have not yet been studied for food application. Yet, hemicelluloses can be used as food additives (thickener, stabilizer, etc) mainly in bakery products. The literature being incomplete regarding the chemical structure of rapeseed hemicelluloses, one of the objectives of this project is to study their physicochemical properties, in regard with their technofunctional properties. Rapeseed hemicelluloses can also be used as raw material to produce an emergent type of prebiotic: xylooligosaccharides (XOS). These molecules can be introduced as well in the food supplement sector. Their production will be achieved by enzymatic hydrolysis, for a polymerization degree between two and five. Thus, the production and the physicochemical and technofunctional characterization of rapeseed XOS constitute the last objective of this project. This thesis is part of the SYNBIOFOR project, which aim is to create new symbiotic ingredients. [less ▲]

From day 103 in gestation until farrowing, 4 successive groups of 15 sows received 70 g per day of one of the 3 following oils: 1) coconut oil (CO); 2) fish oil (FO) and 3) shark liver oil (SO). At day 102 of gestation, at farrowing and at weaning, backfat thickness of the sows was determined. The total number of piglets, the number of piglets born alive, stillborn and dead during the suckling period and the duration of gestation were measured. At birth as well as 24 hours, 14 days and 28 days (weaning) later, the piglets were weighed individually. Colostrum samples were collected at farrowing and 24 hours later for the determination of IgG and IgA contents and the fatty acid profile. Neither performance parameters of the sows nor IgG and IgA concentrations in colostrum were affected by the different dietary treatments. This was probably due to the short duration of trial period in which the oil supplements were administered. However, the colostral fatty acid profiles reflected very well the profiles of the supplemented oils. Furthermore, the different treatments affected the growth performances of the piglets. At weaning, the piglets from the FO treatment were respectively 263 and 329 g heavier than the piglets from the SO and CO treatments (P < 0.05). This corresponded to 4.2 % and 5.8 % increase of the ADG in comparison to the SO and CO treatments, respectively. These results show the importance of the fatty acid composition in colostrum on the performances of piglets and consequently the importance of the feeding of sows at the end of gestation. [less ▲]

Analysis of meat expenditure by Belgian households in 2008. Meat expenditure by Belgian households during 2008 is analyzed. Expenditure is extracted from the Belgian Household Budget Survey at the FPS Economy, S.M.E.s, Self-employed and Energy. The database also provides sociodemographic information about the households participating in the survey. To explain the observed variability of the meat expenditure based on the explanatory factors available, an analysis of the covariance is performed. The three quantitative factors have a bigger effect on the meat expenditure than the three other qualitative factors. The proportion of meat expenditure variability explained by the explanatory factors of the selected model is 31,41%. [less ▲]

Les populations occidentales actuelles accordent de plus en plus d’importance à leur alimentation. Mais Il ne s’agit plus seulement d’intérêts organoleptiques ou hédonistes. Les consommateurs d’aujourd’hui sont plus que jamais attentifs au caractère nutritionnel de ce qui se trouve dans leur assiette. Preuve en est le nombre sans cesse croissant d’alicaments et d’allégations nutritionnelles et de santé qui apparaissant sur le marché. Autre exemple, la tendance graduelle de la part des entreprises agro-alimentaires de « décortiquer » un produit en ses différents nutriments essentiels, tels les protéines, les lipides, les sucres ou encore les fibres. Il est aussi de plus en courant d’y associer le pourcentage de l’apport quotidien recommandé contenu dans le produit. De nos jours, même l’importance des vitamines et des minéraux majeurs (Na, Ca, P, etc.) est ancrée dans les mentalités. Il y a cependant une catégorie de nutriments encore quelque peu délaissée : les oligoéléments. Les oligoéléments sont des éléments chimiques présents en très faibles quantités dans l’organisme mais dont le rôle est essentiel. Les plus connus sont l’iode, le fer, le cuivre le zinc ou encore le manganèse. D’autre par contre sont moins connus mais sont tout aussi indispensables (parfois en plus faible quantités encore) comme le molybdène, le nickel, le chrome, le cobalt et beaucoup d’autres. Les rôles de ces éléments sont aussi diverses qu’indispensables et on les retrouves dans des enzymes et cofacteurs (souvent dans le site actif), dans des hormones, mais ils peuvent aussi jouer un rôle structural (exemple du fluor dans l’hydroxyapatite). Parfois il n’y a qu’un pas à franchir entre oligoélément et élément toxique. C’est par exemple le cas de l’aluminium et de l’arsenic, qui sont nécessaires en petites quantités mais peuvent devenir des poisons (mortels) s’ils sont ingérés à plus forte dose. [less ▲]

A facile and green approach is developed to impart remarkable protection against corrosion to galvanized steel. A protecting multilayer film is formed by alternating the deposition of a polycation bearing catechol groups, used as corrosion inhibitors, with clay that induces barrier properties. This coating does not affect the esthetical aspect of the surface and does not release any toxic molecules in the environment. [less ▲]

Quand les productions animales deviennent positives pour la santé humaine… Vache folle, dioxine, toxi-infections alimentaires, maladies cardiovasculaires… Le secteur de l'élevage est depuis plusieurs années décrié et victime d’une forme de phobie. Mais ces craintes véhiculées par les produits issus de l’élevage sont-elles toujours fondées ? Comment la recherche peut-elle œuvrer pour rendre les produits animaux plus sûrs sur le plan sanitaire ? Nous verrons comment l’œuf de poule, régulièrement associé aux toxi-infections alimentaires, pourrait bien devenir dans le futur un alicament, sérieux allié pour lutter contre les infections animales et humaines.
