Culture of the marine diatom Phaeodactylum tricornutum with different nitrogen sources: Growth, nutrient conversion and biochemical composition
(Station Biologique de Roscoff, 1995)
[Abstract] Cultures of the marine diatom Phaeodaetylum trieornutum were grown in nitrate, nitrite, ammonia or urea media.
Nitrogen transformation efficiencies were close to 100% in cultures with nitrate, nitrite or urea, ...
Purification and characterization of phycocyanin from the marine cyanobacterium Synechococcus sp. IO9201
(Elsevier, 1998-08-07)
This paper describes a suitable method for the optimum extraction and isolation of phycocyanin from the cyanobacterium Synechococcus sp. IO9201 isolated from Caribbean waters. Phycocyanin from this microorganism was purified ...

[Résumé] Croissance et composition biochimique de la microalgue TetrasellIIis sllecica dans des cultures mixotrophiques
avec différents sucres et aminoacides. Trois sucres, fructose, saccharose et manose et trois acides ...
Disorders provoked by copper in the marine diatom Phaeodactylum tricornutum in short-time exposure asays
(Station Biologique de Roscoff, 1997)
[Abstract] Copper toxicity on the marine diatom Phaeodactylwn tricomutum was assessed after 24.liours of exposure, using
different parameters: growth, 14C-bicarbonate assimilation, 3H-thymidine incorporation, photosynthetic ...
Response of the marine microalga Dunaliella tertiolecta (Chlorophyceae) to copper toxicity in short time experiments
(Springer, 1995-02)
Heavy metals are introduced into aquatic ecosystems from industrial wastes, agricultural runoff and mining activities. The toxicity of heavy metal ions in solution to microalgae is well known. The essentiality and toxicity ...
Tolerance and detoxification mechanisms in marine diatom Phaeodactylum tricornutum exposed to cadmium
(Springer, 1995)
Tolerance is one of the most important mechanisms for survival. Organisms living in polluted environments with heavy metals develop tolerance to these contaminants; this tolerance has been attributed to the ability to ...
Changes in the gross chemical composition of mass cultures of the marine microalga Dunaliella tertiolecta with different aeration rates
(Elsevier, 1995)
The effect of different aeration rates, in the range 0–6·51 l of air min−1 l of culture−1, and CO2 supply on the biochemical composition of mass cultures of the marine microalga Dunaliella tertiolecta was studied. The ...
Toxic action of copper on the membrane system of a marine diatom measured by flow cytometry
(WILEY-Liss, 1996-09)
Flow cytometric measurements were used to investigate the toxic action of copper on some Phaeodactylum tricornutum membrane systems. Throughout the time of metal exposure, the percentage of viable cells decreased as copper ...
