Heavy metals are ubiquitous contaminants of the marine environment and can accumulate and persist in sediments. The toxicity of metal contaminants in sediments to organisms is dependent on the bioavailability of the metals in both the water and sediment phases and the sensitivity of the organism to the metal exposure. This study investigated the effects of two metal contaminants of concern (CdC...

The effects of phytohormone Kinetin on cell density, photosynthetic pigments, antioxidant enzymes, and fatty acids composition the microalgae Tetraselmis suecica were investigated. T. was treated with different concentrations (0, 5, 10, 15, 20, 25 mg/L) at optimal growth conditions (salinity 28 g/L, temperature 25°C, 24 hr photoperiod). Results indicated an increase in density all treatments co...

Exposure of cells to ultraviolet B (UVB) radiation can induce production of free radicals and reactive oxygen species (ROS), which damage cellular components. In addition, these agents can stimulate the expression of matrix metalloproteinase (MMP) and decrease collagen synthesis in human skin cells. In this study, we examined the anti-photoaging effects of extracts of Tetraselmis suecica (W-TS)...

Tetraselmis suecica is a green microalga that thrives under wide range of conditions, used in the commercial culture fish, mollusk, and crustacean larvae for supplementing demand fertilizers. Its pigments have applications human health care as drug products, vitamins, cosmetics. Growth pigment concentration T. were evaluated experimental cultures with different nutrient concentrations light int...

Abstract This study examines how salinity reduction triggers the response of three marine microalgae at molecular and unicellular levels in terms chemical, mechanical, behavioral changes. At lowest salinity, all microalgal species exhibited an increase membrane sterols behaved stiffer. The glycocalyx-coated Dunaliella tertiolecta was surrounded by a thick actin layer showed highest physiologica...

Five microalgae strains, namely Isochrysis galbana, Microchloropsis gaditana, Scenedesmus obliquus, Nannochloropsis oculata and Tetraselmis suecica, were selected as potential candidates for polyunsaturated fatty acids’ production, evaluating biomass productivity their capacity to accumulate high lipid contents under different trophic modes. Microalgae strains cultivated in the presence of 1% g...
