Full textDue to the social and political issues about the restoration of burned forests, this work deals with the impact of forest fires on organic and inorganic matters from forested soils collected in Maures Moutains, taking into account the fire temporal recurrence. This studied site was chosen because every year it undergoes an important pressure from wildfire. Among the three main objectives, the first one was to highlight the impact of the fire frequency on the soil quality, studying more precisely the organic matter and some nutrients. Moreover, we wanted to find fire indicators among many elements and polycyclic aromatic hydrocarbons. Finally, we searched to develop a tool for the management and characterization of burned soils using near infrared spectroscopy. The sampling was done for 2 soil layers in 30 sites involving different fire regimes. After the repeatability test of the employed analytical methods, the results show that fires have an impact on soil. Generally, the fires preferentially affect soil surface layers in a qualitative and quantitative way. If the fires have an impact on the soils, it is usually negative because one year after the last event, the soils present losses of the organic pool and nutrients. In addition, some elements could be considered as potential fire indicators in the long term. Comparatively to the elements, the studied PAH with the lowest molecular masses seem to be good fire indicators in the short term. Lastly, this work enabled to validate and envisage the use of a tool for the burned soil management, by the NIR spectroscopy coupled to chemometrics treatments

Full textThe aliphatic and aromatic biomarker content from terrestrial and marine sediments of Late Ordovician to Early Carboniferous age have been related to their palynomorph assemblages (e.g. acritarchs, prasinophytes, chitinozoans, cryptospores, trilete spores and megaspores) in order to contribute to the knowledge of land plant evolution during the Palaeozoic. This investigation is therefore focused on the land-derived biomarkers and their attributions to specific kind of plants. The biomarker record of middle Silurian – lower Devonian sediments from southern Tunisia, Ghadamis Basin (Gondwana) reveals the presence of retene, cadalene, kaurane, norabietane, tetrahydroretene, C19 isohexylalkylnaphthalene and simonellite. The early Palaeozoic bryophytes and tracheophytes (e.g. Cooksonia, lycophytes and zosterophylls) may therefore be considered as potential precursors for retene and its related molecular compounds in sediments of Middle Silurian to Early Devonian age. In contrast, the Early Carboniferous flora formed by arborescent lycopods, sphenopsids and pteridosperms have been suggested here as apossible terrestrial source for phyllocladane, abietane, ent-beyerane, bisnorsimonellite, diaromatic totarane, diaromatic sempervirane and 2-methylretene in the Lower Carboniferous (Viséan) coal deposits at Dunbar (East Lothian, Scotland). Among the other biomarkers detected in our samples, ionene, alkyldibenzofurans, perylene and combustion-derived polycyclic aromatic hydrocarbons (PAHs) indicate pollen, lichens, fungi and vegetation fire contributions, respectively. Most of the biomarkers identified here had been so far generally associated to conifers, though conifers only evolved during Late Carboniferous. Thesecompounds therefore are also characteristic of early land plants

Full textPhenylpropanoids (PPs) are one of the largest families of plants secondary metabolites. They protect plants against biotic and abiotic stresses. Nowadays, extensive research has been dedicated to PPs aiming their use as natural alternatives to synthetic antimicrobial, antioxidant and anti-inflammatory agents in food and pharmaceutical formulations. However, PPs suffer from a low water solubility, high volatility, high light and thermal sensitivity that limit their further use. This current study aimed to encapsulate seven PPs in host cage molecules, cyclodextrins (CDs), in order to develop natural and biocompatible formulation that may find applications in food and pharmaceutical fields. It focused on three main research axes. The first part dealt with the preparation and the characterization of CD/PP inclusion complexes both in solution and in solid state. Characterizations were performed with Static-Headspace-Gas Chromatography (SH-GC), UV-Visible, ¹H NMR, (2D) ROESY NMR, FTIR, DSC and molecular modeling. These investigations were complemented with phase solubility studies. The second part was devoted to the evaluation of the effect of CDs on the PPs photostability and controlled release. The last part aimed to evaluate the CD/PP inclusion complexes as radical scavengers, antibacterial and antifungal agents. Results showed that CDs could successfully encapsulate PPs, reduce their volatility, enhance their solubility and photostability and generate controlled release system. In addition, encapsulation maintained the antioxydant, antibacterial and antifungal properties of PPs. Thus, the CD/PP inclusion complexes could be considered as a promising tool for formulation optimization

Full textThis thesis is focused on the measurements of isotopic and elementary compositions of hydrogen and nitrogen in the Insoluble Organic Matter (IOM) isolated from the carbonaceous chondrites and Wild 2 materials collected by the Stardust mission. Analysis were performed by means of secondary ions mass spectrometry (SIMS). In this thesis, an effort was done to quantify the N/C ratio in the IOM. The precision on the N/C ratio is improved by collecting secondary ions with similar physical parameters, in that case molecular ions C−2 and CN−. The IOM in carbonaceous chondrites shows that isotopic anomalies in hydrogen and nitrogen are spatially correlated for the most of them. For the non -correlated anomalies, enrichments in D and 15N are decoupled. Apart from isotopic ratios, no classification of these isotopic anomalies can be done on the basis of their elementary H/C and N/C ratios. The isotopic fractionation of the hydrogen is not systematically correlated with the nitrogen isotopic fractionation. The measured Wild 2 cometary grains have chondritic carbon and nitrogen isotopic compositions. Two peculiar grains bearing isotopic anomalies were observed, probably condensed in stellar envelopes of novae stars. One of these grains is composed of organic matter as shown by its spectrocopic signature
