Green microalgae contain many active pigments such as carotenoids having antioxidant and protective activity on human cells. Here we investigate the biological activity of an ethanol/water extract of the marine green microalga Tetraselmis suecica containing high levels of carotenoids such as the xanthophylls lutein, violaxanthin, neoxanthin, antheraxanthin and loroxanthin esters. This extract h...

This study evaluates the nutritional value of several species of freeze-dried microalgae used to feed the seed of Ruditapes decussatus. These microalgae were: Isochrysis galbana, clone T-ISO; Tetraselmis suecica; and Phaeodactylum tricornutum. The addition of antibiotics, kaolin and fresh microalgae to the freeze-dried diet was also evaluated, and a study was made of the nutritional value of on...

Algae are plant organisms that produce organic molecules in the aquatic environment and absorb carbon. Since algae photosynthetic organisms, they give oxygen to environment. Algae, one of most important living resources seas, used many fields such as food, agriculture, cosmetics, medicine, pharmacy, industry also a biofuel source thanks metabolites store cell. In study carried out determine eff...

We analyze the influence of greenhouses in cultivation phytoplankton. For this we propose a model for marine green algae Tetraselmis suecica, and adapt it to four other species (Spirulina platensis, Dunaliella salina, Phaeodactylum tricornutum Chlorella vulgaris). Experiments under greenhouse were carried out shifting temperature two raceways compared reference raceway with free evolving temper...

This study was performed to compare the efficiency of six microalgae namely Dunaliella tertiolecta, Tetraselmis suecica, Nannochloropsis oculata, Chaetoceros sp., Chlorella sp. and Spirolina sp. on the growth, survival rate and reproduction efficacy in Artemia urmiana in laboratory conditions. Artemia cysts were harvested from Urmia Lake and hatched according to the standard method. Live microa...

While copepods are important prey for many wild marine fish larvae and preferred as a live feed culturing larval fish, their low productivity the costs associated with them typically limit use food source in all but experimental situations. In series of experiments four readily commercially available microalgae (Thalassiosira weissflogii Grunow, Rhodomonas salina Wislouch, Tetraselmis suecica K...
