Cadmium tolerance and removal in the marine microalga Dunaliella salina were studied in cultures exposed to different metal concentrations (5-120 mg Cd l(-1)) for 96h. This microalga can be included in the group of microalgal species most tolerant to cadmium due to the high value of EC50 that it possesses (48.9 mg Cd l(-1) at 96 h of culture). The greater percentage of cadmium removed was obtai...

Dunaliella salina is a unicellular green microalga that is considered as one of the best commercial sources of carotenoids. Growth and pigment production of D. salina (isolated from Sambhar Salt Lake, Rajasthan) was studied by using various inorganic media differing in chemical compositions viz. Artificial Sea Water media, De Walne’s media, Johnson’s media, AS-100 and Modified Bold’s Basal medi...

The extracts and sesquiterpene lactones of S.argentinum were assayed to determine their biological activity on Artemia salina. The most active compound was costunolide (1) with LD50= 62 ppm. Introduction Our previous phytochemical study of Stachychephalum argentinum (Asteraceae), revelead the presence of several skeletal types sesquiterpene lactones [1]. In order to explore new natural bioactiv...

Paracetamol has a reasonable safety profile when taken in therapeutic doses. However, it could induce hepatotoxicity and even more severe fatal acute hepatic damage when taken in an overdose. The green alga, Dunaliella salina was investigated for hepatoprotective and antioxidant activity against paracetamol-induced liver damage in rats. Male albino Wistar rats overdosed with paracetamol showed ...

The current study examines the antimicrobial and antioxidant properties of different extracts of the microalga Dunaliella salina Teodoresco (Dunaliellaceae), their fatty acid composition and the antimicrobial activity of the oil. Antimicrobial and antioxidant activities were evaluated by obtaining extracts of D. salina in n-hexane, dichloromethane, ethanol, and methanol. To evaluate the antimic...

Dunaliella salina and D. bardawil are well-known microalgae accumulating high levels of beta-carotene under growth-limiting conditions. In both taxa, this pigment is primarily composed of the isomers 9-cis and all-trans. The 9-cis beta-carotene occurs only in natural sources and is the most attractive from a commercial point of view. The conditions that enhance the preferred accumulation of 9-c...

The American brine shrimp Artemia franciscana is invasive in the Mediterranean region where it has displaced native species (the sexual A. salina, and the clonal A. parthenogenetica) from many salt pond complexes. Artemia populations are parasitized by numerous avian cestodes whose effects have been studied in native species. We present a study from the Ebro Delta salterns (NE Spain), in a salt...

PURPOSE Ultraviolet B (UVB) radiation from sunlight is known to be a risk factor for human corneal damage. The purpose of this study was to investigate the protective effects of Dunaliella salina (D. salina) on UVB radiation-induced corneal oxidative damage in male imprinting control region (ICR) mice. METHODS Corneal oxidative damage was induced by exposure to UVB radiation at 560 μW/cm(2). ...

Dunaliella salina (D. salina) is a potential source of lipids and subsequent biodiesel production. However lipid production from dependent on biomass production rate and lipid content. To get more lipid, production efficiency need to be improved. The aim was to application of two-stage culture strategy for improved microalgal growth and lipid Production. In this study the culture was grown unde...
