Green synthesis of gold nanoparticles by the marine microalga Tetraselmis suecica [PDF]

Biotechnology and Applied Biochemistry, 2010
The application of green‐synthesis principles is one of the most impressive research fields for the production of nanoparticles. Different kinds of biological systems have been used for this purpose. In the present study, AuNPs (gold nanoparticles) were prepared within a short time period using a fresh cell extract of the marine microalga Tetraselmis ...

Cadmium removal by living cells of the marine microalga Tetraselmis suecica [PDF]

Bioresource Technology, 2002
Cadmium removal by living cells of the marine microalga Tetraselmis suecica was tested in cultures exposed to different cadmium concentrations (0.6, 3, 6, 15, 30 and 45 mg/l). The EC50 for growth was 7.9 mg Cd/l after six days of exposure. The cadmium removed was proportional to the concentration of this metal in the medium and it was dependent on the ...

Changes in mortality rates during the larval stage of the Pacic white shrimp (Litopenaeus vannamei) on the basis of algal (Chaetoceros calcitrans or Tetraselmis suecica) food density

Ecosistemas y Recursos Agropecuarios, 2016
In the shrimp culture, larval stages have high mortality rates, particularly in the zoea stage, this because to the star of phytoplankton feeding and an inadequate microalga species and cell density used in commercial hatcheries.

Toxicity of Organophoshorous pesticides to the marine alga Tetraselmis Suecica [PDF]

Global NEST Journal, 2013
Organophoshorous pesticides are widely used in agriculture, because most of them are high effective and low persistent. Yet their increased usage has elicited extensive research into pesticide effects on non-target organisms, such as algae. Algae are of vital importance in the primary production of aquatic ecosystems.

Marine and freshwater micropearls: biomineralization producing strontium-rich amorphous calcium carbonate inclusions is widespread in the genus Tetraselmis (Chlorophyta) [PDF]

Biogeosciences, 2018
Unicellular algae play important roles in the biogeochemical cycles of numerous elements, particularly through the biomineralization capacity of certain species (e.g., coccolithophores greatly contributing to the organic carbon pump of the oceans ...

Purification and Structure of Antioxidative Substance Derived from Tetraselmis suecica [PDF]

Korean Journal of Fisheries and Aquatic Sciences, 2002
Tetraselmis suecica (T. suecica) of Prasinophyta was selected because the growth rate is comparatively higher and the culturing is also easy. In order to investigate antioxidative activity, the soluble elements of T. suecica were fractionated using water and organic solvents such as methanol, hexane, chloroform, ethylacetate and butanol. The chloroform
