Twelve microalgae species isolated in tropical lagoons of New Caledonia were screened as a new source of antioxidants. Microalgae were cultivated at two light intensities to investigate their influence on antioxidant capacity. To assess antioxidant property of microalgae extracts, four assays with different modes of action were used: 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2’-azinobis (3-éthylbenzothiazoline-6-sulphonique) (ABTS), oxygen radical absorbance capacity (ORAC), and thiobabituric acid reactive substances (TBARS). This screening was coupled to pigment analysis to link antioxidant activity and carotenoid content. The results showed that none of the microalgae studied can scavenge DPPH and ABTS radicals, but Chaetoceros sp., Nephroselmis sp., and...

On the basis of hydrological and biological data collected between 1983 and 1987 along the French coast, and especially in the southern approaches to Brittany. it has been possible to compare different parameters in an attempt to explain the seasonal variations of a toxic dinoflagellate: Dinophysis sp. speveral species were identified and their seasonal distribution patterns are described. The origin of the blooms, from either coastal endemic or offshore populations, is considered Tipo: Text Palavras-chave: Dinophysis; Distribution saisonnière; Côtes françaises; Dinophysis; Seasonal distribution; French coast. Ano: 1988 URL: https://archimer.ifremer.fr/doc/00189/30067/28555.pdf Effects of Nitrogen Availability on the Antioxidant Activity and Carotenoid Content of the Microalgae Nephroselmis sp ArchiMer Coulombier, Noémie; Nicolau, Elodie; Le Déan, Loic; Barthelemy, Vanille; Schreiber, Nathalie; Brun, Pierre; Lebouvier, Nicolas; Jauffrais, Thierry. Nephroselmis sp. was previously identified as a species of interest for its antioxidant properties owing to its high carotenoid content. In addition, nitrogen availability can impact biomass and specific metabolites’ production of microalgae. To optimize parameters of antioxidant production, Nephroselmis sp. was cultivated in batch and continuous culture conditions in stirred closed photobioreactors under different nitrogen conditions (N-repletion, N-limitation, and N-starvation). The aim was to determine the influence of nitrogen availability on the peroxyl radical scavenging activity (oxygen radical absorbance capacity (ORAC) assay) and carotenoid content of Nephroselmis sp. Pigment analysis revealed a specific and unusual photosynthetic system with... Tipo: Text Palavras-chave: Lutein; Natural products; Nutrients; Peroxyl radical; Siphonaxanthin.
