Full textThe main objective of this research was to determine the potential bioindicator of certain enzymatic activities to characterize the functioning and quality of soil in the context of metal and organic pollutions (i. E. Pesticides and conventional, organic or biological, and integrated management strategies). In a first step, a methodology for the quantification in soils of phenol oxidase activities has been developed, and further study on its sensitivity towards certain metals has been performed. Thereafter, different approaches have been apprehended through incubation under controlled laboratory conditions and field observations, made at scales ranging from plot to landscape. The enzymes studied are involved in the functioning of the major biogeochemical cycles of C (cellulase, fluorescein diacetate hydrolase, β-galactosidase, β-glucosidase and phenol oxidase), N (arylamidase), P (acid and alkaline phosphomonoesterases, phosphodiesterase and phosphotriesterase) and S (arylsulfatase). The results have clearly demonstrated the variability of response patterns of enzyme activities, with the type of contamination and physical and chemical characteristics of soils. This underlines the difficulty for selecting universal enzymatic bioindicators of soil quality for a wide range of perturbations. However, some enzymes, such as arylamidases and phenol oxidases, proved repeatedly to be indicators especially sensitive to disturbance applied to the different soils of this study. An interesting continuation of this work would be to integrate such kind of study of these potential bioindicators in networks of soil quality measurement. Finally, other microbial parameters were also studied, the functional diversity of bacterial communities (Biolog® Eco) and bacterial and fungal densities, but they have proved to be less relevant as soil quality indicators with regards to enzyme activities

Full textThe reduction of salt (NaCl) content in food has become a matter of public health. However, the multiple functions of salt in food make the reduction of its content difficult. The aim of this work was to demonstrate the applicability of NMR innovative techniques in order to characterise the mobility of sodium ions (distinction between ‘free’ and ‘bound’ sodium), to bring a better understanding of the role of salt in the organisation of the food matrix (in particular phosphorous molecules in dairy systems) and to study impact of salt on the mobility of aroma compounds. In a first step, the 23Na NMR study of iota-carrageenan gels validated the quantification of total sodium (Single-Quantum, SQ experiment) and also demonstrated the involvement of ‘bound’ sodium ions in the gelation process of this polysaccharide (Double-Quantum Filtered, DQF experiment). The diffusion of aroma compounds in these systems was measured by 1H DOSY NMR, but no specific impact of salt was evidenced. The second step was dedicated to study dairy systems and semi-hard cheeses by 23Na NMR and solid-state 31P NMR using the magic angle spinning (MAS) technique. We demonstrated the feasibility of 23Na NMR methods for the quantification of total sodium and the characterisation of Na motional state (presence of ‘bound’ ions) in these systems. 31P MAS NMR (simple pulse excitation, SPE and cross-polarisation, CP) enabled the identification of different phosphorous compounds (inorganic phosphate, colloidal calcium phosphate, phosphoserins), the determination of their proportions and also permitted to determine the involvement of these phosphorous compounds in the protein network of coagulated systems. With these results, we achieved to identify the parameters of composition (or processing) influencing the dynamics of sodium ions in real cheeses. We also determined the distribution of phosphorous compounds, in particular inorganic phosphate, in these cheeses. This work demonstrates that these 23Na and 31P NMR innovative techniques are perfectly applicable to real food and can help to adjust the manufacturing process of cheeses in order to optimise their sensory and functional properties
