Cadmium toxicity on the freshwater microalga Chlamydomonas moewusii Gerloff: Biosynthesis of thiol compounds
(SETAC-Press (Society of Environmental Toxicology and Chemistry), 2010-09)
Cadmium (Cd) toxicity and production of different thiols (phytochelatins, glutathione, γ-Glu-Cys and cysteine) were studied in the microalga Chlamydomonas moewusii exposed to different concentrations of this metal (1, 2, ...
β-carotene, vitamin C and vitamin E content of the marine microalga Dunaliella tertiolecta cultured with different nitrogen sources
(Elsevier, 1991)
Variations in the β-carotene, vitamin C and vitamin E content of D. tertiolecta have been shown to result from the nitrogen source used in the culture medium. Differences of 101%, 38% and 69% have been found in β-carotene, ...
Effect of cadmium on growth, ATP content, carbon fixation and ultrastructure in the marine diatom Phaeodactylum Tricornutum Bohlin
(Springer, 2000-01)
Cadmium toxicity to the diatom Phaeodactylum tricornutum Bohlin has been studied on the basis of the effect of this metal on growth, ATP content, 14C uptake and cellular ultrastructure. The microalga was exposed to 1, 5, ...
Variations in the biochemical profile of the marine microalga Dunaliella tertiolecta (Butcher) cultured with different nutrient concentrations and urea as a nitrogen source
(Station Biologique de Roscoff, 1994)
[Abstract] Variations in the biochemical profile of the marine microalga Dunaliella tertiolecta (Butcher) cultured
with different nutrient concentrations and urea as a nitrogen source.
Cultures of the marine microalga ...
Growth, chlorophyll α and protein of the marine microalga Isochrysis galbana in batch cultures with different salinities and high nutrient concentrations
(Elsevier Science Publishers, 1985)
Cultures of the marine microalga Isochrysis galbana were grown under 56 different nutrient concentration-salinity conditions, ranging from 1 to 64 mM NaNO3 and from 0 to 35‰ salinity. Salinity and nutrient concentration ...
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 ...
Approach to biomass production of the marine microalga Tetraselmis suecica (kylin) butch using common garden fertilizer and soil extract as cheap nutrient supply in batch cultures
(Elsevier Applied Science Publishers, 1987)
We report the possibility of an economic cultivation of the marine microalga Tetraselmis suecica, using different mixtures of a common garden fertilizer, soil extract, micronutrients and vitamins. Maximum cellular densities ...
Response of the Marine Microalga Dunaliella tertiolecta to Nutrient Concentration and Salinity Variations in Batch Cultures
(Gustav Fisher Verlag, 1986)
The marine microalga Dunaliella tertiolecta is known for its ability to tolerate a wide range of salt concentrations. Cultures were grown under 56 different nutrient concentration-salinity conditions. Optimal growth ...
