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 ...
Sulphate, more than a nutrient, protects the microalga Chlamydomonas moewusii from cadmium toxicity
(Elsevier, 2014-03)
Sulphur is an essential macroelement that plays important roles in living organisms. The thiol rich sulphur compounds, such as cysteine, γ-Glu–Cys, glutathione and phytochelatins participate in the tolerance mechanisms ...
Comparison of the sensitivity of different toxicity test endpoints in a microalga exposed to the herbicide paraquat
(2009-02)
[Abstract]The use of herbicides constitutes the principal method of weed control but the introduction of these compounds into the aquatic environment can provoke severe consequences for non-target organisms such as microalgae. ...
Class III metallothioneins in response to cadmium toxicity in the marine microalga Tetraselmis suecica (Kylin) Butch
(Wiley, 2001-09)
Microalgae are one of the most important organisms in our ecosystems being seriously affected by metal pollution. However, the microalgae Tetraselmis suecica (Kylin) Butch is tolerant to cadmium; the concentration of this ...
Analysis and enhancement of astaxanthin accumulation in Haematococcus pluvialis
(Elsevier, 2005-02)
The green microalga Haematococcus pluvialis was cultured with different concentrations of NaNO3 to determine the effect on cell growth and astaxanthin accumulation. The optimum nitrate concentration to obtain astaxanthin ...
Isobolographic analysis of the interaction between cadmium (II) and sodium sulphate: toxicological consequences
(Springer, 2016)
Sulphate is an essential nutrient for autotrophic organisms and has been shown to have important implications in certain processes of tolerance to cadmium toxicity. Sodium sulphate is the main salt of sulphate in the natural ...
Composition and production of thiol constituents induced by cadmium in the marine microalga Tetraselmis suecica
(Wiley, 2006-01)
Time course of intracellular levels of different thiols (phytochelatins, desglycyl-phytochelatins, glutathione, γ-glutamylcysteine [γ-Glu-Cys], and cysteine) were studied in the microalga Tetraselmis suecica exposed to ...
Flow cytometric analysis of the encystment process induced by paraquat exposure in Haematococcus pluvialis (Chlorophyceae)
(Taylor & Francis, 2011)
The freshwater microalga Haematococcus pluvialis exhibits a unique morphological response to environmental stress, accumulating carotenoid pigment during encystment. The complexity of characterizing the different cell ...
Variations in planktonic bacterial biomass and production, and phytoplankton blooms off A Coruña (NW Spain)
(CSIC, 2003)
[Abstract] Bacterial abundance, biomass and heterotrophic activity, along with hydrographic and phytoplankton variables,
were measured from February 1998 to September 1999 at two coastal stations off A Coruña (Galicia, ...
