Yields in biomass and chemical constituents of four commercially important marine microalgae with different culture media [PDF]

, 1991
The use of the commercial nutrient Algal-1 was studied in mass cultures of the marine microalgaeTetraselmis suecica, Dunaliella tertiolecta, Isochrysis galbana and Phaeodactylum tricornutum, in comparison with the use of media such as ES-Provasoli, and ...

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 ...

Toxicity induced by three antibiotics commonly used in aquaculture on the marine microalga Tetraselmis suecica (Kylin) Butch [PDF]

, 2014
Aquaculture facilities are a potential source of antibiotics to the aquatic ecosystems. The presence of these compounds in the environment may have deleterious effects on non-target aquatic organisms such as microalgae, which are often used as biological

Mass culture and biochemical variability of the marine microalga Tetraselmis suecica Kylin (Butch) with high nutrient concentrations [PDF]

, 1985
Mass cultures of Tetraselmis suecica were carried out with four nutrient concentrations, ranging from 2 to 16 mM of NaNO3 and salinity 35‰. An air flow of 15 l/min maintained a CO2 transference rate sufficient to keep the pH below 8.4.

Grazers and Phytoplankton Growth in the Oceans: an Experimental and Evolutionary Perspective [PDF]

, 2013
The taxonomic composition of phytoplankton responsible for primary production on continental shelves has changed episodically through Earth history. Geological correlations suggest that major changes in phytoplankton composition correspond in time to ...

High yield mixotrophic cultures of the marine microalga Tetraselmis suecica (Kylin) Butcher (Prasinophyceae) [PDF]

, 1992
The effects of three organic compounds were tested on one of the most used marine micro-algae in the aquaculture of molluscs and crustaceans, Tetraselmis suecica. Studies were made in axenic conditions with yeast extract, peptone and glucose added to 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.

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 ...
