Study of the chemical composition of edible red macroalgae Grateloupia turuturu from Brittany (France)
Biochemical and behavioural responses of the endobenthic bivalve Scrobicularia plana to silver nanoparticles in seawater and microalgal food.
Spatiotemporal changes in microphytobenthos assemblages in a macrotidal flat (Bourgneuf Bay,France) 1
A significant role is suggested for epipsammon biomass, until now underestimated, in the functioning of this turbid coastal ecosystem, where oyster beds and ridge and runnel features appeared to be local spatial structuring factors allowing the establishment of specific assemblages.

The aim of this study was to contribute to a better understanding of turbid coastal ecosystems, focusing on spatio-temporal changes at the mesoscale in microphytobenthos structures in a macrotidal…
Biochemical and behavioural responses of the marine polychaete Hediste diversicolor to cadmium sulfide quantum dots (CdS QDs): waterborne and dietary exposure.
An evaluation of methods for quantifying the enzymatic degradation of red seaweed Grateloupia turuturu
The proposed procedure based on the quantification of residue surface area seems to be an accurate method to analyze enzymatic digestion and demonstrated that cell walls were only partially digested by polysaccharidase enzymes alone.
Growth form defines physiological photoprotective capacity in intertidal benthic diatoms
The results thus provide the first experimental evidence for the existence of a trade-off between behavioural (motility) and physiological photoprotective mechanisms (NPQ and the XC) in the four major intertidal benthic diatoms growth forms using unialgal cultures.
Effect of enzymatic digestion on thallus degradation and extraction of hydrosoluble compounds from Grateloupia turuturu
The efficiency of the enzy- matic process in degrading the seaweed thallus and the effect of the enzymatic treatment on solubilization of R-phycoerythrin and reducing sugars are studied to confirm the presence of agar, cellulose, k- and i-car- rageenans in the cell wall of Grateloupia turuturu.

This study confirms the potential of marennine as a biologically active organic molecule, which could have a protective effect on bivalves, which filter seawater and fix the pigment on their gills, and used in food engineering and chemistry as a natural blue pigment.
