Influence of darkness on pigments of Tetraselmis indica (Chlorodendrophyceae, Chlorophyta)

Journal of Photochemistry and Photobiology B: Biology, 2018
In the photic zone, phytoplankton experience diurnal variation in light intensity. However, prolonged exposure to aphotic condition influences their physiological state. Pigment composition is a useful biomarker to decipher cells physiological state and adaptive response to changing environmental conditions.

Optimum medium for large-scale culture of Tetraselmis tetrathele

Hydrobiologia, 1997
The prasinophyte Tetraselmis tetrathele is an alga commonly used as live food for aquatic animal larvae. The alga is usually cultured in Guillard & Ryther medium (Guillard F) or a fertilizer enriched seawater medium for the large-scale culture of Nannochloropsis.

An electrophoretic survey of the genus Tetraselmis (Chlorophyta, Prasinophyceae)

Phycologia, 1986
Abstract A survey of the algal genus Tetraselmis (Chlorophyta, Prasinophyceae) was conducted using starch gel enzyme electrophoresis. Thirteen enzyme loci were resolved and scored, of which nine were invariant among strains. Phenotypes at the four variable loci, glyceraldehyde-3-phosphate dehydrogenase-1, glutamate–oxaloacetic transaminase-2, malate ...

Cryopreservation of members of the genus Tetraselmis used in aquaculture

Aquaculture, 1993
Abstract Commercially important members of the genus Tetraselmis were cryopreserved with high levels of post-thaw viability. Levels of post-thaw viability > 50% for T. suecica (Kylin) Butcher were achieved by employing a simple protocol using glycerol as a cryoprotectant; samples were placed in a coolingbath preset at −30°C for 30 min, followed by ...

Response of Tetraselmis suecica to nutrient and grazer manipulation

Journal of Applied Phycology, 1999
Three methods of algal quantification (direct cell counts, chlorophyll a extraction, in vivo fluorescence) were used to evaluate the response of the unicellular green flagellate Tetraselmis suecica to nutrients and grazers. Nutrient enrichment enhanced total cell counts, chlorophyll a concentration and in vivo and DCMU-fluorescence.

Specificity in the Convoluta Roscoffensis/Tetraselmis Symbiosis

1988
Convoluta roscoffensis is an intertidal acoel turbellarian (fflatworm1) that is locally abundant on sandy beaches of the Brittany coast of France and nearby Channel Islands. It is a conspicuous member of the beach fauna, for two reasons: first, the animals are green, due to the presence of algal symbionts of the genus Tetraselmis (=Platymonas ...

Tetraselmis as a challenge organism for validation of ballast water UV systems

Water Research, 2017
Transport and release of waterborne organisms as a result of ballasting and de-ballasting operations is widely acknowledged to represent an important mechanism for invasions by non-indigenous species. Regulatory requirements have been implemented globally to require treatment of ballast water before its release to the environment as a means of ...

Mixotrophic growth of Tetraselmis viridis in axenic culture

Issues of modern algology (Вопросы современной альгологии)
On the example of laboratory culture of Tetraselmis viridis (Rouchijajnen) R.E.Norris, Hori & Chihara, 1980, the possibility of mixotrophic growth of microalgae in the cumulative axenic cultivation mode was experimentally demonstrated. The implementation of mixotrophy consisted in supplying an additional source of energy and carbon to the initial ...
