EThe research tasks undertaken in this thesis lie within the scope of “durable development” and more especially in the agronomic sector. Indeed, one of the possible methods to decrease the excessive contributions of manures, often harmful with the environment, is to support the installation of the plant-microorganism natural interactions. Among them, the endosymbioses including nitrogen fixing and mycorhizal appear. The molecular dialogue between the two partners highlights the presence of a symbiotic signal in the case of the nitrogen fixing symbiosis, called nod factor, which is not other than a lipochito-oligomer. By considering a similarity in the signalising of the two symbioses, it is possible to imagine the existence of a “myc” factor with structure closed to the factor nod one. Nevertheless, the corresponding structure of “myc” factor still remains unspecified. The objective of this thesis is to seek these myc factors to even purify them and in fine, to isolate them. Work was completed according to three approaches. One the basis of an a priori of structure with the nod factor, the molecular imprinting technique was used around a lipochito-oligomer. Then a protocol of labelling with the 2-aminobenzamide was developed. Last, without an a priori of structure, a series of extractions of biological media according to a more traditional biochemical approach was carried out and the activity of the residual fractions was tested directly on the plants. The results from these various approaches made it possible to purify fractions containing compounds of “fungic” origin and to open the way to promising prospects

Due to the widespread use of pesticides, a fraction of pesticide residues are present in fruits and vegetables. Pesticide contamination of food has become one of the serious problems. Global pesticide consumption has increased over the past decade due to continued population growth and rapid urbanization. Pesticides are highly toxic and long-term exposure to these chemicals causes health risks including neurological and respiratory diseases.This study focuses on the evaluation of the concentration of 34 pesticides in 60 conventionally and organically grown vegetables and fruits from various origins. Among these samples, some were studied in different forms, with and without washing, with and without skin. The purpose of the latter is to evaluate whether there is a simple gesture to reduce the content of pesticides in fruits and vegetables and thus reduce the health impacts of consumers.The work focuses firstly on the optimization of the extraction method, purification and final analysis of the extracts. The extraction method QuEChERS (Quick, Easy, Cheap, Rugged, Effective and Safe) and the purification method d-SPE (dispersive Solid Phase Extraction) were used. The final extracts were analyzed by gas chromatography coupled to a tandem mass spectrometer (GC-MS/MS) for the identification and quantification of each pesticide. The set of procedures has been optimized and it provides good sensitivity, selectivity, good yield that varies from 70% to 120%, and good precision with RSD <20%. The application of the method on real samples allows the determination of pesticides in 85% of the samples. The concentrations of pesticides detected in vegetables and fruits did not exceed the maximum residue limits (MRLs) for the majority of pesticides. However, some pesticides were found at levels above MRLs for fruits and vegetables from Akkar in Northern Lebanon. Moreover, among the pesticides detected at high levels are those that have already been banned as in the case of Endosulfan. The results showed that some simple gestures can reduce the levels of pesticide residues in fruits and vegetables. Indeed, washing with tap water and peeling significantly reduce pesticide residues in fruits and vegetables. Organically grown fruits and vegetables have lower pesticide concentrations than conventionally grown ones. Very low pesticide concentrations or in some cases concentrations below the limit of quantification were determined for organically grown fruits and vegetables

Conventional sample preparation methods for the determination of polar compounds such as liquid-liquid extraction (LLE) and solid phase extraction (SPE) are generally not effective because of their multiple steps, low recovery and high consumption of organic solvents. Thus, this thesis deals with the development of new sample preparation methods, i.e, electrochemically modulated liquid-liquid extraction (EMLLE) and bar-micro solid phase extraction (bar-μ-SPE) to determine selected pharmaceutical compounds, i.e., metformin (MET), buformin (BUF), phenformin (PHEN), and propranolol (PROP) having varied lipophilicity in biological samples. In the EMLLE method, the aid of electric field was utilized to extract the pharmaceutical compounds across the interface between two immiscible electrolyte solutions (ITIES). ITIES formed when two bulk solvents aqueous phase (lithium chloride) and organic phase (I,2-dichloroethane), both containing electrolytes are brought into contact. Transfer potential for each analyte was analysed by voltammetry. The trend of transfer potential followed their lipophilicity; propranolol < phenformin < phenyl biguanide < metformin. Extraction of the analytes was performed by applying fixed potential to the biphasic system using potentiostat for 15 mins. The extraction performance was poor. Design of another ITIES cell and imposing interfacial potential by chemical polarization was done to enhance the extraction performance of this method. Thus, the EMLLE technique based on application of interfacial potential due to the presence of different concentrations of tetramethylammonium ion (TMA+) as common ion in each phase was studied. The optimum extraction conditions for this method are, [TMA+]o = 10 mM, [TMA+]w = 0.001 mM, Vorg = 2 mL, pHsample = 9, rotation speed = 900 rpm, extraction time = 600 s. The optimised parameters for back-extraction are: [TMA+]back = 50 mM, Vfinal = 0.1 mL, pHback = 2 . Nearly 100 % extraction of targeted analytes was achieved, and the enrichment factor obtained was up to ~ 60 for biguanide compounds. In the bar-μ -SPE method, adsorbent and a tiny metal rod was placed in a polypropylene membrane bag. Among the various adsorbents studied, graphene and zeolite showed some potential. Thus, extraction conditions were optimised for each adsorbent and adsorbent mixture. Despite the optimisations, the extraction was low (5.03-39.2 %). Nevertheless, enrichment factors of 1.49 -14.9 were obtained. Both proposed methods were applied to the determination of the analytes in urine. On the whole, the newly proposed methods are simple and markedly reduced consumption of organic solvents

This PhD thesis was a Cotutelle between the Université de Pau et des Pays de l’Adour (UPPA) in Pau, France and the Christian-Albrechts University (CAU) in Kiel, Germany. In the course of this international collaboration, bio-analytical methods for the quantitative and qualitative analysis of labelled peptides and proteins were developed, which were based on the hyphenation of chromatography with mass spectrometry. Peptides and protein digests were lanthanide labelled using DOTA-based compounds according to an optimised protocol. Separation on the peptide level was performed using IP-RP-nanoHPLC. Complementary data sets were acquired using MALDI-MS for identification and ICP-MS for quantification. In this context, an online precleaning step was developed and implemented in the nanoHPLC separation routine, which allowed for effective removal of excess reagents. This lead to lowered metal backgrounds during ICP-MS measurements and thus better data interpretability, while guarding peptide recovery at a maximum level. An alternative offline purification using solid phase extraction (SPE) resulted in important peptide losses and can be considered unsuitable for quantitative analysis. Additives to the nanoHPLC eluents, such as HFBA and EDTA were tested and not deemed beneficial for the analysis of normal peptide samples. HFBA can be reconsidered for special application on very hydrophilic peptide species. A set of labelled peptides was developed, which due to application of known quantities could be employed for quick and simple quantification of a low complexity digest sample. In addition this peptide set allowed for the reliable superposition of chromatograms, enabling sample comparability especially for complementary ICP-MS and MALDI-MS data. Experiments for application of fsLA-ICP-MS on MALDI-MS target plates were conducted and showed very promising results. For this purpose, samples that were already identified using MALDI-MS were supposed to be remeasured using fsLA-ICP-MS. First quantification attempts on the modified steel target plate were successful and in the range of expectance. Adjusted parameters for MALDI-MS allowed for proper peptide identifications
