| In mollusk aquaculture, a large number of Vibrio species are considered major pathogens. Conventional methods based on DNA amplification and sequencing used to accurately identify Vibrio species are unsuitable for monitoring programs because they are time-consuming and expensive. The aim of this study was, therefore, to develop the MALDI-TOF MS method in order to establish a rapid identification technique for a large panel of Vibrio species. We created the EnviBase containing 120 main spectra projections (MSP) of the Vibrio species that are potentially responsible for mollusk diseases, comprising 25 species: V. aestuarianus, V. cortegadensis, V. tapetis and species belonging to the Coralliilyticus, Harveyi, Mediterranei, and Orientalis clades. Each MSP was... |

| Ce travail porte sur la caractérisation hivernale de la lagune de Bizerte en se basant sur une campagne de mesures effectuée en janvier 2004. Cette campagne a porté sur 17 stations réparties sur toute la lagune ainsi qu’une station marine de référence. Chaque échantillon a fait l’objet de mesures in-situ (Température, Salinité, Conductivité, Transparence, Acidité et Oxygène dissous) et des analyses au laboratoire (NO3, NO2, NT, PO4, Chlorophylle-a, Phéopigment et MES). Cette étude a montré que la distribution spatiale des paramètres est fortement liée aux apports fluviaux. Contrairement au phosphore minéral, la teneur en azote total montre une variation spatiale importante. L’analyse de la distribution spatiale des nutriments d’une part et de la... |

| This work concerns the development of a three dimensional hydroecological model based on two nutrient elements, nitrogen and phosphorus.The hydrodynamic model is 3D forced by monthly climatic data of NOAA. The ecological model was developed based on two nutrient elements, nitrogen and phosphorus in interaction with the phytoplankton and zooplancton. The ecological model is made up with two compartments, the water column and the sediment layer. Eight state variables are used to characterize the water column and six state variables for the sediment layer. As a first application, the model was tested on the Bizerte Lagoon. A comparison between simulations and observations showed that the model can reproduce with satisfactory way the observations carried out... |
