The present study has revealed that, the temperature has a crucial role among the observed physiochemical parameters on the growth and survival of P. margaritifera spat. Instantaneous growth rates (IGRs) in DVM, APM and TWT were calculated and used to assess the variation in growth of spat reared with different feed mixtures (FM-1 8) of five diatoms and stocking densities (SD-10, 20 and 30). Am...

Abstract Isochrysis galbana is a microalga that potential source of several ‘compounds interest’ for food and nutraceutical industries. The procurement these compounds interest the generation bioenergy novel interesting application microalgae. present study evaluated valorization I. through extraction carotenoid fucoxanthin polyunsaturated fatty acids using supercritical fluid (SFE). spent or e...

Copper (Cu) uptake and trophic transfer in marine plankton at the environmentally relevant levels have rarely been investigated. In this study, we investigated Cu subcellular distribution five phytoplankton ( Isochrysis zhanjiangensis , Phaeocystis sp., galbana, Chaetoceros sp. Phaeodactylum tricornutum ) belonging to two taxa Chrysophyta Bacillariophyta, following rotifer Brachionus plicatilis...

Three polysaccharides, IPSI-A, IPSI-B and IPSII, were successfully isolated from the marine microalgae Isochrysis galbana through a combination of anion-exchange column chromatography and repeated gel chromatography. These three polysaccharides were demonstrated to have moderate scavenging activities against superoxide and hydroxyl radicals and moderate reductive power in a concentration-depend...

Azadinium spinosum (Elbrächter and Tillmann), a small marine dinoflagellate, has been recently described as a de novo producer of azaspiracid-1 and -2 (AZA1 and -2) diarrhoeic toxins. A culture of A. spinosum was established in our laboratory and optimised for pilot-scale production of this organism, to evaluate and understand AZA1 and -2 accumulation and biotransformation in blue mussels (Myti...
