Physiological response of freshwater microalga (Chlorella vulgaris) to triazine and phenylurea herbicides
(2002-09)
[Abstract]The effects of two herbicides used wide-spread, isoproturon (phenylurea) and terbutryn (triazine), on growth, dry weight, elemental composition, photosynthetic pigments and protein content, and cell volume assayed ...
Atrazine-Induced Chlorosis in Synechococcus elongatus Cells
(Springer, 2004)
The effects of a widely used herbicide, atrazine, on the freshwater cyanobacterium Synechococcus elongatus were studied. The cyanobacteria were exposed to varying concentrations of atrazine (0.025, 0.05, 0.1, 0.25, and ...
Biomass production and biochemical composition in mass cultures of the marine microalga Isochrysis galbana Parke at varying nutrient concentrations
(Elsevier Science Publishers, 1986)
Mass cultures of Isochrysis galbana were carried out with four nutrient concentrations ranging from 2 to 16 mM of NaNO3 and salinity 35‰. An air flow of 15 l/min maintained a CO2 transference rate sufficient to keep the ...
Rapid assay for the analysis of class III metallothioneins by capillary zone electrophoresis in crude extracts of microalgal cells exposed to cadmium
(Elsevier, 1997-07-18)
An optimization strategy for the separation and analysis of class III metallothioneins from a complex matrix by capillary zone electrophoresis (CZE) is presented and illustrated. Metallothioneins are a group of polypeptides ...
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 ...
Riboflavin enrichment throughout the food chain from the marine microalga Tetraselmis suecica to the rotifer Brachionus plicatilis and to White Sea Bream (Diplodus sargus) and Gilthead Sea bream (Sparus aurata) larvae
(2008-10)
[Abstract]The riboflavin enrichment of the marine microalga Tetraselmis suecica and the transfer of this vitamin to higher trophic levels of the aquatic food chain such as the rotifer Brachionus plicatilis and the larvae ...
Effect of oil and dispersant on growth and chlorophyll a content of the marine microalga Tetraselmis Suecica
(American Society for Microbiology, 1984)
[Abstract] Low hydrocarbon concentrations stimulated the growth of Tetraselmis suecica, whereas higher concentrations (200 ppm) inhibited growth. The content of chlorophyll a in this microalga was affected in a similar ...
Growth of the marine microalga Tetraselmis suecica in batch cultures with different salinities and nutrient concentrations
(Elsevier Science Publishers, 1984)
The marine microalga Tetraselmis suecica is known for its ability to tolerate a wide range of salt concentrations. Cultures were grown under 48 different nutrient concentration-salinity conditions, ranging from 2 to 64 mM ...
High yield mixotrophic cultures of the marine microalga Tetraselmis suecica (Kylin) Butcher (Prasinophyceae)
(Springer, 1992-03)
The effects of three organic compounds were tested on one of the most used marine micro-algae in the aquaculture of molluscs and crustaceans, Tetraselmis suecica. Studies were made in axenic conditions with yeast extract, ...
Cadmium removal by living cells of the marine microalgaTetraselmis suecica
(2002-09)
[Abstract] Cadmium removal by living cells of the marine microalga Tetraselmis suecica was tested in cultures exposed to different cadmium concentrations (0.6, 3, 6, 15, 30 and 45 mg/l). The EC50 for growth was 7.9 mg Cd/l ...
