Changes in protein, carbohydrates and gross energy in the marine microalga Dunaliella tertiolecta (Butcher) by nitrogen concentrations as nitrate, nitrite and urea
(Elsevier Science Publishers, 1989)
Cultures of the marine microalga Dunaliella tertiolecta were grown in nitrate, nitrite and urea at concentrations ranging from 0·25 to 16 mg atom. N/litre.
Great biochemical variability has been shown in this microalga ...
Nutritional properties of four marine microalgae for albino rats
(Springer, 1993-12)
The nutritive value of the marine microalgaeTetraselmis suecica, Isochrysis galbana, Dunaliella tertiolecta and Chlorella stigmatophora was studied in diets given to rats. Biological assays were carried out in order to ...
Yields in biomass and chemical constituents of four commercially important marine microalgae with different culture media
(Elsevier, 1991)
The use of the commercial nutrient Algal-1 was studied in mass cultures of the marine microalgaeTetraselmis suecica, Dunaliella tertiolecta, Isochrysis galbana and Phaeodactylum tricornutum, in comparison with the use of ...
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, ...
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 ...
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 ...
Biochemical composition and growth of the marine microalga Dunaliella tertiolecta (Butcher) with different ammonium nitrogen concentrations as chloride, sulphate, nitrate and carbonate.
(Elsevier Science Publishers, 1989)
Cultures of the marine microalga Dunaliella tertiolecta were grown in ammonium chloride, sulphate, nitrate and carbonate at concentrations ranging from 0.25 to 16 mg.atom N/l. Cells were harvested in the stationary phase ...
Biomass production and biochemical variability of the marine microalga Dunaliella tertiolecta (Butcher) with high nutrient concentrations
(Elsevier Science Editors, 1986)
Mass cultures of Dunaliella tertiolecta were carried out in 10-l flasks with four nutrient concentrations in order to obtain a maximum biomass production and to find out its biochemical variability. Using these cultural ...
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 ...
Decrease in plasma cholesterol, triglycerides and CPK levels in rats fed on the marine microalga Dunaliella tertiolecta
(Geor Thieme Verlag, 1986)
The dried marine microalga Dunaliella tertiolecta was fed to weaning albino rats for 12 days as the sole protein source at a protein level of 12% protein from casein. Plasma cholesterol, triglycerides, and CPK levels were ...
