Effects of nitrogen source and growth phase on proximate biochemical composition, lipid classes and fatty acid profile of the marine microalga "Isochrysis Galbana"
(1998-07)
[Abstract]The marine microalga Isochrysis galbana was cultured in nitrate, nitrite or urea media to examine changes in the gross biochemical composition, with special emphasis on the growth phase associated changes in the ...
Long-chain class III metallothioneins as a mechanism of cadmium tolerance in the marine diatom Phaeodactylum tricornutum Bohlin
(1997-11)
Cadmium tolerance of the marine diatom Phaeodactylum tricornutum Bohlin was studied. P. tricornutum growth was significantly reduced by cadmium concentrations of 5 mg l−1 or higher. The EC50 value was 22.39 mg l−1 of cadmium ...
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 ...
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 ...
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 ...
