Study of the chemical composition of edible red macroalgae Grateloupia turuturu from Brittany (France)
The chemical composition and its seasonal variation of the red seaweed Grateloupia turuturu, an invasive macroalgae from Brittany, France, were investigated. Size, ash, protein, lipid, dietary fibre… Expand

Because of their bactericidal effects, Ag nanoparticles (Ag NPs) have promising industrial development but could lead to potential ecological risks. The aim of this study was to examine the uptake… Expand
Spatiotemporal changes in microphytobenthos assemblages in a macrotidal flat (Bourgneuf Bay,France) 1
Spatiotemporal changes in microphytobenthos species composition were investigated in relation to structural variables—biomass; life‐forms; detritus ratio, pheopigment a (pheo a):chl a; and sediment… Expand
An evaluation of methods for quantifying the enzymatic degradation of red seaweed Grateloupia turuturu
For better exploitation of the red seaweed Grateloupia, enzymatic digestion of the thallus may be a way to increase access to metabolites of industrial interest. With this aim, we have tried to find… Expand
Spatio-temporal changes in microphytobenthos structure analysed by pigment composition in a macrotidal flat (Bourgneuf Bay, France)
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… Expand
Effect of enzymatic digestion on thallus degradation and extraction of hydrosoluble compounds from Grateloupia turuturu
The extraction of metabolites of industrial interest from seaweed tissue is difficult due to the presence of anionic polysaccharides in the cell walls. We studied enzymatic digestion of Grateloupia… Expand
Biochemical and behavioural responses of the marine polychaete Hediste diversicolor to cadmium sulfide quantum dots (CdS QDs): waterborne and dietary exposure.
Cadmium sulfide (CdS) quantum dots are widely used in medical imaging. The aim of this study was to examine toxicity effects of CdS engineered nanoparticles (CdS NPs) compared to soluble Cd, on… Expand
Growth form defines physiological photoprotective capacity in intertidal benthic diatoms
In intertidal marine sediments, characterized by rapidly fluctuating and often extreme light conditions, primary production is frequently dominated by diatoms. We performed a comparative analysis of… Expand

Marennine, the blue pigment produced by the diatom Haslea ostrearia , exists in two different forms, the intra- and extracellular forms. We investigated the antibacterial, antiviral, and… Expand
Heterothallism in the pennate diatom Haslea ostrearia (Bacillariophyta)
Twelve clonal cultures of the marine pennate diatom Haslea ostrearia (Gaillon) Simonsen were used to study sexual reproduction and auxosporulation. After crossing, compatible gametangia paired girdle… Expand
