Copper toxicity on the marine microalga Phaeodactylum tricornutum: effects on photosynthesis and related parameters
(Elsevier, 1995-02)
Essential heavy metals, as copper, can be toxic for microalgae at high concentrations. Copper affected growth and other parameters closely related to photosynthesis of the marine diatom Phaeodactylum tricornutum. A copper ...
Removal of cadmium ions by the marine diatom Phaeodactylum tricornutum Bohlin accumulation and long-term kinetics of uptake
(Elsevier, 1998-03)
The marine diatom Phaeodactylum tricornutum Bohlin was exposed to different cadmium concentrations (1–100 mg l−1) for 4 days. The amount of cadmium removed was recorded, with particular attention paid to long-term uptake ...
Potential use of flow cytometry in toxicity studies with microalgae
(2000-03)
[Abstract]Cytotoxic effects of aquatic pollutants on microalgae are very heterogeneous, and they are influenced by environmental conditions and the test species. Stress produced by copper or paraquat addition to the culture ...
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, ...
Screening acute cytotoxicity biomarkers using a microalga as test organism
(Elsevier, 2012-12)
The present study checked the suitability of the integration of flow cytometry (FCM) as technique and a freshwater microalga (Chlamydomonas moewusii) as cell system model for ecotoxicological studies, looking for sensitive ...
Atrazine induced changes in elemental and biochemical composition and nitrate reductase activity in Chlamydomonas reinhardtii
(Taylor & Francis, 2016)
Herbicides play an important role in agricultural practices but the introduction of these compounds into the aquatic environment can have severe consequences for non-target organisms such as microalgae. The ubiquitous green ...
Crecimiento y composición bioquímica de la microalga marina Tetraselmis suecica en cultivos mixotróficos con distintos azúcares y aminoácidos
(Station Biologique de Roscoff, 1992)
[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 ...
A Comparison of the Relative Sensitivity of Structural and Functional Cellular Responses in the Alga Chlamydomonas eugametos Exposed to the Herbicide Paraquat
(Springer, 1999-04)
The effect of the herbicide paraquat on the freshwater microalga Chlamydomonas eugametos was studied in function of different parameters such as growth, elemental composition, total lipids, and photosynthetic pigments ...
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 ...
