D. salina is one of the recognized natural sources to produce beta-carotene, and an useful model for studying the role of inhibitors and enhancers of carotenogenesis. However there is little information in D. salina regarding whether the isoprenoid substrate can be influenced by stress factors (carotenogenic) or selective inhibitors which in turn may further contribute to elucidate the early st...

Energy consumption and water resource in the cultivation and harvesting steps still need to be minimized for the popularization of the microalgae-based products. An efficient electro-flocculation method for harvesting Dunaliella Salina integrated with local sand has been successfully applied. Sand was effective for speeding up the processes of flocculation and sedimentation of algal flocs and t...

We isolated the matrix attachment region-binding protein (MBP) DMBP-1 from Dunaliella salina in our previous studies. MBPs are part of the cis-acting protein family cluster. The regulatory function possibly works through the interaction of the MBPs with each other. In the present study, DMBP-1 was used as the bait in screening the D. salina cDNA library for DMBP-1 interactors that could potenti...

Beta-carotene is a valuable carotenoid in high demand as a natural food coloring agent, provitamin A, additive to cosmetics, and health food. It can be accumulated up to more than 10% of cellular dry weight of Dunaliella salina under carotenogenic conditions such as high irradiance, high temperature, high salt concentration and nutrient deficiency. High beta-carotene productivity in Dunaliella ...

Microalgae are a source of carbohydrates, proteins and lipids. Thus, they can be considered as raw material to transition from current fossil fuel-based refineries biorefineries. harvesting is major challenge in biomass production. There several techniques, but the majority them either expensive or not effective. The method that we propose sedimentation-induced by light blockage, taking advanta...

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...
