Abstract:

This thesis applies the ab initio techniques of computational chemistry to studies of molecular clusters containing covalent (strong) or van der Waals (weak) bonds formed in chemistry and biochemistry in the temperature range 10-300 K. Van derWaals complexes with an enthalpy of formation from reactants of less than 25 kJ mol-1 and covalent clusters are described in this thesis. The first group of van der Waals complexes involved the molecule carbon monoxide that possesses a small permanent dipole that could lead to dipole - induced dipole interaction and dipole - dipole interaction

Abstract:

Negli ultimi anni, il mercato dei probiotici si è evoluto rapidamente, grazie al crescente interesse dei consumatori nei confronti dei prodotti funzionali. Sebbene siano molti i benefici dei probiotici sulla salute umana ad oggi ipotizzati, solo per pochi ceppi l’effetto benefico è stato dimostrato attraverso studi in vivo. Il presente lavoro, inserendosi nel complesso filone della probiosi, ha inteso individuare nuovi ceppi potenzialmente probiotici definendone anche nuovi criteri di selezione. A tal proposito sono stati individuati 8 ceppi di diversa origine appartenenti a Lactobacillus rha

Le but de ce projet était de développer la technologie d'électro-activation comme une approche novatrice pour la valorisation intégrale des constituants du lactosérum. Ce sous-produit est riche en composants de valeur avec des propriétés biologiques et fonctionnelles prometteuses. La première étape de ce travail visait à déterminer les conditions optimales pour la production du lactulose en utilisant le lactosérum comme source de lactose. Un rendement de 35% a été obtenu avec une pureté élevée à des températures de 0, 10 et 25°C et un court temps de réaction (≅ 40 minutes). En outre, l'analyse

Abstract:

Titan, la plus grosse lune de Saturne, est l'un des objets planétaires clé dans le domaine de l'exobiologie. Son atmosphère dense et riche en diazote est le siège d'une chimie organique intense. Ce travail de thèse se concentre sur les aérosols organiques produits dans son atmosphère. Ces derniers jouent un rôle essentiel dans l'évolution de l'atmosphère et de la surface du satellite mais aussi dans sa chimie organique d'intérêt exobiologique. Dans un premier temps, afin de disposer d'analogues de laboratoires (« tholins ») fiables de ces aérosols, un dispositif permettant d'obtenir des tholin

Abstract:

Extraction of fructo-oligosaccharide syrups from grated jerusalem artichoke (JA) tubers was studied by water at 20-60&deg<br>C by determining the yield, degree of polymerization (DP), product profile (DP of up to 6) and prebiotic effect using Lactobacillus plantarum on samples harvested between October and April, stored for 0-20 days. The optimum solvent to solid ratio was 4, the duration of shaking water bath extraction was 40 min and yield based on JA were 12-17%. Temperature was found to improve yield and functionality, and citric acid, at 26 mM, improved the color and darkness by 70 and 80

Abstract:

Marine macroalgae have a long tradition of usage and applications among the far Eastern populations, either for direct consumption and nutrition or for medicinal purposes. During the recent years, these marine organisms have received increasing popularity among the Western populations which are becoming aware of their potential to be exploited as a source of valuable bioactive compounds. Among these compounds are the phlorotannins, which are a group of phloroglucinol-derived phenolic compounds occurring exclusively on brown seaweeds and claimed for their promising health-promoting

In addition, different sugars were useed as carbon sources to study mannanase induction for this strain. Finally, mannan hydrolysates were used to cultivate bifidobacteria to understand their growth-enhanceing effect. The optimum culture conditions for mannanase production were as follow: defatted coconut meal 3.12% (w/v), yeast extract 8.67 g/L, initi

Abstract:

This project involved the development of a synbiotic dairy product and its use in human feeding trials to quantify the hypocholesterolemic and antihypertensive effects of probiotics on hypercholesterolemic men and women. To this end, eleven strains of Lactobacilli and three strains of Bifidobacteria were evaluated for their acid and bile tolerance, cholesterol removal ability and hypotensive properties in vitro. Our results showed that all studied strains were able to tolerate pH 2.0 for two hours. However, strains of L. acidophilus in general were more acid-resistant than Bifidobacteria
